m = (11 - 8)/(4 - 2.5) = 3/1.5 = 2What is the value FG?
FG is not a defined term, so there is no way to determine its value.
FG is not a defined term, so there is no way to determine its value. This means that we cannot assign a numerical or other value to it. In order to determine the value of FG, we would first need to identify the context in which it is being used, as different contexts may assign different meanings to the same term. Once the context has been established, we can then look up the definition of FG in order to understand what it means in that particular context, and then assign a value to it accordingly. For example, if FG stands for "Frequency Generator" in a physics context, then it would likely have a numerical value associated with it.

The three steps which Patel could use to solve the quadratic equation include the following:
A. 8(x² + 2x + (2/2)²) = -3 + 8.
B. x = -1 ±√5/8
E. 8(x² + 2x) = -3.
How to solve the quadratic equation?In order to solve the given quadratic equation, we would use the completing the square method as follows;
Separating the variables in the quadratic equation from constant, we have the following;
8x² + 16x + 3 = 0
8x² + 16x = -3
By factorizing the common variables in the quadratic equation from constant, we have the following;
8(x² + 2x) = -3 (step 1).
By completing the squares in the brackets and then balancing the expression on the right-hand side, we have the following;
8(x² + 2x + (2/2)²) = -3 + 8 (step 2).
8(x² + 2x + 1) = -3 + 8
8(x + 1)² = 5
Dividing both sides of the quadratic equation by 8, we have the following;

What number would you need to multiply the first equation by to eliminate the y variable when solving the system of equations by elimination?
We would need to multiply the first equation by -4 to eliminate the y variable when solving the system of equations by elimination.
The first equation is: 3x + 4y = 5
To eliminate the y variable when solving the system of equations by elimination, we need to multiply the first equation by -4. This is because when two equations are multiplied by the same number, any terms that have the same variable will be eliminated when the equations are added together.
Formula:
3x + 4y = 5
-4(3x + 4y = 5)
3x + 4y = 5
-12x - 16y = -20
Thus, we would need to multiply the first equation by -4 to eliminate the y variable when solving the system of equations by elimination.

i’m not sure how to find the slope of the lines
Answer:
Step-by-step explanation:Select any two random points on the graph of the line (preferably with integer coordinates).
Label them as A and B (in any order).
Calculate the "rise" from A to B. While going vertically from A to B, if we have to go
"up", then the rise is positive;
"down", then the rise is negative.
Calculate the "run" from A to B. While going horizontally from A to B, if we have to go
"right", then the run is positive;
"left", then the run is negative.
Now, use the formula: slope = rise/run.

What is 2 point midpoint?
The 2-point midpoint formula is a method for finding the equation of a line that passes through the midpoint of two given points.
The formula for the 2-point midpoint is:
y - y1 = m(x - x1)Where (x1, y1) and (x2, y2) are the two given points, and m is the slope of the line.
The slope of line is calculated by (y2-y1)/(x2-x1)
By using the midpoint of two given points, the 2-point midpoint formula eliminates the need for calculating the y-intercept of the line, which can save time and effort. It is particularly useful when working with geometric figures or real-world applications that involve moving objects or changing data. It also helps in predicting the values of future point when we know the past point.

I have x N50 note and y N100 note. There are eight note altogether and their total value i N550. How many of each note do I have?
So I have 5 and 3 notes each
You need to use simultaneous equations to solve this problem since there are 2 variables.
50x + 100y = 550 (value of the notes x the number of each note)
x + y = 8 (the number of each note added).
Multiply the second equation by 50 so that it the x variables are the same in both equations. Thus, 50x + 50y = 400.
Subtract 50x + 50y = 400 from 50x + 100y = 550.
The subtraction results in 50y = 150.
Divide by 50. y = 3, so x must equal 5.
So I have 5 and 3 notes each

What are exponents?The exponent of a number shows how many times the number is multiplied by itself.
Example: 2×2×2×2 can be written as 24, as 2 is multiplied by itself 4 times. Here, 2 is called the "base" and 4 is called the "exponent" or "power."
In general, xⁿ means that x is multiplied by itself for n times.
Properties of exponents:
Law of Product: a ^m × a ^n = a ^(m + n)
Law of Quotient: a ^m/a ^n = a ^(m - n)
Law of Negative Exponent: a^-m = 1/a ^m
Law of Power of a Product: (ab)^m = a ^m . b ^m
Law of Power of a Quotient: (a/b) ^m = a ^m/b ^m
Given expression
2a³b⁻⁴/3a⁵b⁻²

Kate has $400. She wants to have $430 to buy a couch. How much interest would she have to earn in order to get the additional $30?
Select the best answer from the choices provided.
A. 3%
B. 4.5%
C. 6%
D. 7.5%
Answer:
D) 7.5%
Step-by-step explanation:
We can solve this through guessing and checking, or we can do this mathematically. We will try both approaches.
Mathematically:
We know that to get the extra $30 if we have $100, is a 30% interest. Now, since we have 4x 100, and these numbers are inversely proportional, we will need to divide 30 by 4. Doing this gives us 30/4 = 7.5, so the answer is 7.5%.
Guess and Check:
This way is a bit slower, but we will go through each answer and find how much money we would get from them. So, we would take our percent, change it to a number of that percent, considering we are taking it from 100, and multiply it by 4 since we have $400. We will get each of these respectively:
A) 3% = 3 * 4 = $12
B) 4.5% = 4.5 * 4 = $18
C) 6% = 6 * 4 = $24
D) 7.5% = 7.5 * 4 = $30
As you can see, D) gives us that extra $30, so the answer is D) 7.5%.

A farmer sells eggs at a market. She offers three different sizes.
For any size, the weight of each egg can vary up to 8%.
Calculate the missing values in the table.
Is it possible for an egg to be both large and extra large?
Yes
The missing values in the table can be calculated by multiplying the given weights by 0.92 and 0.88 to get the maximum and minimum weights for each size.
Small egg:
Minimum weight = 1.2 * 0.92 = 1.104 ounces;
Maximum weight = 1.2 * 1.08 = 1.296 ounces
Medium egg:
Minimum weight = 1.6 * 0.92 = 1.472 ounces;
Maximum weight = 1.6 * 1.08 = 1.728 ounces
Large egg: Minimum weight = 2 * 0.92 = 1.84 ounces; Maximum weight = 2 * 1.08 = 2.16 ounces
Extra Large egg: Minimum weight = 2.4 * 0.92 = 2.208 ounces; Maximum weight = 2.4 * 1.08 = 2.592 ounces
Yes, it is possible for an egg to be both large and extra large, as long as the weight of the egg is between 1.84 and 2.592 ounces.

After a long morning of sledding, Mrs. Fieldhouse made a batch of hot cocoa for her daughter and nighborhood friends. She divided it among 8 mugs. Each mug had more than 9 fluid ounces of hot cocoa. Write an inequality to describe the situation.
x>9 perfectly describes the situation.
In mathematics, inequalities characterise the connection between two non-equal numbers. Inequality implies being unequal. If two values are not equal, we use the "not equal symbol ()". However, various inequalities are employed to compare the numbers, whether they are less than or higher than.
Let x be the amount of hot cocoa in fluid ounces that each mug contains.
Since each mug has more than 9 fluid ounces of hot cocoa, we can write the inequality as:
x > 9
We also know that the total amount of hot cocoa made is 8 mugs * the amount of hot cocoa in each mug = 8x.
So the inequality can be written as:
8x > 9*8 = 72

What is the probability that it is green or yellow?
Pls pls help!

Thx!
The probability to draw a green bead is 1/3 and the probability to draw a green or yellow bead is 2/3
It is given that the bag contains 1 red bead, 2 yellow beads, 2 green beads, and 1 blue bead.
Hence the total no. of beads in the bag = no. of red + yellow + green + blue beads
= 1 + 2 + 2 + 1 beads
= 6 beads.
Let the event to draw a green bead be A
Let the event to draw a yellow bead be B
Probability of any event = no. of outcomes favorable to that event/ total number of outcomes
Hence P(A) = no. of green beads/ total no. of beads
= 2/6
= 1/3
Hence the probability that a green bead is drawn is 1/3
P(B) = no. of yellow beads/ total no. of beads
2/6 = 1/3
We need to find P(A or B)
= P(A U B) = P(A) + P(B) - P(A ∩ B)
P(A ∩ B) = P(A and B)
Since no bead is of 2 colors, P(A ∩ B) = 0
Hence we get
P(A U B) = 1/3 + 1/3
= 2/3
Hence the probability to draw a green or yellow bead is 2/3

After diving the polynomials, the quotient and remainder is q(x)=-x^2+1 and r(x)=-1 respectively.
What are polynomials?
The word "polynomial" is derived from the Greek words "poly" and "nominal," which combined translate to "many phrases." There is no limit to the number of terms that can exist in a polynomial.
The polynomials are -
a(x)=-x^4
b(x)=x^2+1
Divide a(x) by b(x).
-x^4/x^2+1 = -x^2+1 with remainder as -1.
The quotient is obtained as q(x)=-x^2+1 and the remainder is r(x)=-1.
The given equation is -
a(x)/b(x)=q(x)+[r(x)/b(x)]
Plugging in all the values -
-x^4/x^2+1=-x^2+1+[-1/x^2+1]
[-x^4/x^2+1]-[-1/x^2+1]=-x^2-1
-x^4+1/x^2+1=-x^2-1
-x^4+1=[-x^2+1][x^2+1]
-x^4+1=(-x)^2[x^2+1]+(1)[x^2+1]
-x^4+1=-x^4-x^2+x^2+1
-x^4+1=-x^4-1
So, LHS=RHS is proved using the equation.
Therefore, the quotient is q(x)=-x^2+1 and the remainder is r(x)=-1.
