Write the equation of the line in standard form:
4y=2x+9
Answers
2x - 4y + 9 is the equation of the line in standard form.
What is standard form?Ax + By=C is the typical form for linear equations involving two variables. A linear equation in standard form is, for instance, 2x + 3y=5.
Finding both intercepts of an equation in this format is fairly simple (x and y). When resolving systems of two linear equations, this form is also really helpful.
Lets write the equation of the line in standard form:
4y=2x+9
We know that standard form = Ax + By=C
⇒ 4y = 2x + 9
⇒ 2x - 4y + 9
Here,
Ax = 2x
By = -4x
C = 9
Thus, 2x - 4y + 9 is the equation of the line in standard form.

Taub is a high school basketball player. In a particular game, she made some three point shots and some two point shots. Taub made a total of 11 shots altogether and scored a total of 30 points. Graphically solve a system of equations in order to determine the number of three point shots made, x, and the number of two point shots made, y.
Answers
x + y = 11
3x + 2y = 30
x + y = 11 because x and y show the number of 2 and 3 point shots and 11 is the total number of shots
3x + 2y = 30 since each ‘x’ shot represents 3 points, and each ‘y’ shot represents 2 points, and 30 is the total number of points.
All you have to do now is plot your equations on a graph, and see where the lines intersect!
Or, we can solve the equations like this:
x + y = 11 and 3x + 2y can’t be cancelled out since there are no matching variables. We can multiply one equation to make them match:
2 ( x + y = 11) = 2x + 2y = 22
We can cancel out 2y in the first and second equations through subtraction, leaving x = 8.
Through substitution, we can find out y’s value:
x + y = 11
x = 8
y = 11 - 8 = 3
y = 3
Check if your answer is correct: 3x + 2y = 30
3 x 8 + 2 x 3
= 24 + 6
= 30

The area of circle with circumference 5πm is 6.25π square meters.
What is circumference and area of a circle?
The measurement of the circle's perimeter, also known as the circle's boundary, is called its circumference.
Circumference of circle(C)= 2πr
The area of a circle is the space encircled or encompassed by its circumference. It has a square unit of measurement.
Area of circle(A)= πr^2
We are given the circumference of circle(C)= 5π
This implies that 2πr= 5π because C= 2πr
On solving the equation,
2πr= 5π
r=5/2
=2.5
Now, area of circle(A)= πr^2
So, A= π (2.5)^2
A= 6.25π square meters
Hence, The area of circle with circumference 5πm is 6.25π square meters.

Answers
Brianna will use 0.17 liters of the liquid
We know that an equation in which two ratios are set equal to each other is called as proportion.
Here, Brianna has a container which has 0.85 L of liquid in it.
Brianna needs to use 0.2 of this liquid.
Assume that 0.85 L represents the 100% of the liquid.
Then 0.2 represents 0.2 × 100 = 20% of the liquid .
Let Brianna will use x liters of liquid.
Consider a proportion.
[tex]\frac{0.85}{100} =\frac{x}{20}[/tex]

2): x - $31 = $69
Step-by-step explanation:
See attached worksheet. The derivation of the answer, x - $69 = $31 (then x = $100) is shown. Convert the written question into an equation: If x is the amount given the cashier, then once $69 is subracted, Lemon receives $31:
x - $69 = $31
This can be rearranged to: x - $31 = $69, the second answer option. Other options have errors, noted by the red circles. There are no reasons that inequalities are involved, and seemingly random values of $61 and $30 have no relationship to the problem.
Answer:
B) Let x = amount paid to cashier
x - $31 = $69
x = $100
Step-by-step explanation:
We want to determine the amount Lemon paid the cashier. Therefore, the unknown variable is:
Let x = the amount he paid the cashier.If Lemon received $31 in change, then the amount he paid the cashier less the change is equal to the cost of the walnuts:
x - $31 = $69To solve the equation, add $31 to both sides:
x - $31 + $31 = $69 + $31x = $100Therefore, the amount Lemon paid the cashier was $100.

Answers
On a negatively skewed curve The mean is lower than the median which is lower than the mode. The correct answer is E.
Why is a curve negatively skewed?In statistics, a distribution is said to be negatively skewed if more values are concentrated on the right side (tail) of the distribution graph and the left tail is longer.
Positive skew is characterized by a longer or fatter tail on the right side of the distribution, and negative skew is characterized by a longer or fatter tail on the left. These two skews represent the direction or weight of the distribution.
The central tendency of a distribution is defined as its mean, median, and mode. The fact that the mean, median, and mode of the typically skewed data are all equal demonstrates the equality of wealth and income distribution as well as the significance of governmental policies and economic progress.
The distributions have a wide gap because the negative side is so heavily weighted. For instance, the data shows that the distribution of income is unequal and negatively skewed, and the central tendency is as follows:
Mode > Median > Mean.

We want to find the equation for g(x).
First, the function is stretched vertically by a factor of 4. This means that the function changes as follows:
f(x)→4f(x)
Therefore, the function becomes:
4(8x)
=32x
Then, it is translated 7 units down. This means that the function changes as follows:
f(x)→f(x)-7
Therefore, the equation for g(x) is:
g(x)=32x-7

Nathan bought a wallet for 5% off its full price. What was the full price of the wallet if nathan paid $17. 67 before sales tax?.
Answers
The full price of the wallet that Nathan bought before the discount is $18.60
In this case, we are given that:
The total price after the discount = $17.67
Let’s assume that the full price of the wallet is X
The discount = 5% off = 0.05 X
We can find the full price by using this following formula:
Full price – discount price = total price after discount
X – 0.05X = 17.67
0.95X = 17.67
X = 17.67 : 0.95
X = 18.6

Penelope’s pool holds 1,350 gallons and she is draining the water at a rate of 1.6 gallons per minute. How long will it take to have the same amount of water in both pools?
how many minutes?
Answers
At the time t, we know that the amount of water that Isabella has drained is equal to the amount of water Penelope has drained.
1,700 gallons - 2.4 gallons/min * t = 1,350 gallons - 1.6 gallons/min * t
Now we will get rid of the gallons, by multiplying both sides by 1 min/gallons
t = (1,700 - 1,350)/(2.4 - 1.6) = 350 / 0.8 = 437.5 min.
So it would take Isabella and Penelope 437.5 minutes (about 7.29 hours) to have the same amount of water in both pools.

How do you find the end behavior of a graph with Asymptotes?
Answers
To find the equation of an asymptote from a graph, look for the line that the graph approaches but never touches. Then calculate the slope of the line and the y-intercept. This will give you the equation of the asymptote.
How to find an asymptote?To find the equation of an asymptote from a graph, look for the line that the graph approaches but never touches. Asymptotes usually run parallel to the x-axis or the y-axis, so look for a straight line that is horizontal or vertical.
Once you have identified the line, calculate the slope of the line and the y-intercept. The slope of the line is the ratio of the change in the y-values to the change in the x-values.
Once you have found the slope and the y-intercept, you can use the slope-intercept form of a line to find the equation of the asymptote: y = mx + b, where m is the slope and b is the y-intercept. This will give you the equation of the asymptote.
