Answer:
x = [tex]\frac{J-Hy}{G}[/tex]
Step-by-step explanation:
This question is from the topic subject of formula. It implies expressing x in terms of G, H y and J.
Given that: Gx + Hy = J
Subtract Hy from both sides to have;
Gx + Hy - Hy = J - Hy
⇒ Gx = J - Hy
Then divide both sides by G, so that we have;
x = [tex]\frac{J-Hy}{G}[/tex]
Therefore,
x = [tex]\frac{J-Hy}{G}[/tex]

factor(s), 2
72
Answer:
2^7 ≠ 7^2
Step-by-step explanation:
2^7 = 2 * 2 * 2 * 2 * 2 * 2 * 2
The only factor is 2
7^2 = 7 * 7
The only factor is 7
Comparing the factors when written as a repeated multiplication,
2^7 and 7^2 have no common factor :
2^7 = 2 * 2 * 2 * 2 * 2 * 2 * 2 = 128
7^2 = 7 * 7 = 49

Answer:
[tex]\sqrt{21}[/tex]
Step-by-step explanation:
Use the pythagorean theoreom, a^2+b^2=c^2.
We know the hypontenuse and one of the sdes
a^2+2^2=5^2
a^2+4=25
subract four from both sides to isolate variable
a^2=21
square root both sides and you have the answer of sq root 21!

Here is a diagram of a person standing next to a tree.
The diagram shows two centimeter rulers.
The tree and the person are drawn to the same scale.
The person is approximately 1.65 m tall.
Using the scale diagram, estimate the height of the tree in meters
Answer:
9.9 m
Step-by-step explanation:
According to the scale the person is 2 cm tall, and the tree is 12 cm tall.
So we know that the tree is 6 times taller than the person because,
12 cm = 6 x 2 cm
The actual height of the person is 1.65 m.
Since we know that the tree is 6 times taller than the person, we can find the height of the tree to be
6 x 1.65 m = 9.9 m
On average, Haley is able to read 4 5/6 Chapters in the her book each week . How many weeks will it take Haley to read 9 2/3 Chapters
Answer:
2 weeks
Step-by-step explanation:
y = mx + b
y = total number of chapters read = [tex]9\frac{2}{3}[/tex]
m = number of chapters read per week = [tex]4\frac{5}{6}[/tex]
x = number of weeks = what we're solving for
b is not needed to find this solution
[tex]9\frac{2}{3}[/tex] = [tex]4\frac{5}{6}[/tex] x divide [tex]4\frac{5}{6}[/tex] from both sides
x = 2 weeks

f(x) = -2x + 2
g(x) = 3x^2– 3x
Find f (4) and g(-3)
helpp please i would appreciate it
Answer:
f(4) = -6, g(-3) = 36
Step-by-step explanation:
To find f(#) or g(#), plug the number into each x of the equation.
f(x) = -2x + 2
f(4) = -2(4) + 2
Simplify the parentheses by multiplying.
f(4) = -8 + 2
Add.
f(4) = -6
g(x) = 3x² - 3x
g(-3) = 3(-3)² - 3(-3)
Simplify the exponent first.
g(-3) = 3(9) - 3(-3)
Simplify the parentheses by multiplying.
g(-3) = 27 + 9
Add.
g(-3) = 36

Maliki is building a ramp with a base of 4 feet and a vertical height of 2 feet. What is the length of the ramp?
Answer:
2√5
Step-by-step explanation:
By applying Pythagoras (hypotenuse)^2=(Base)^2 +(Height)^2
The length of the ramp is approximately 4.47 feet.
What is the Pythagorean theorem?Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.
If the base of the ramp is 4 feet and the vertical height is 2 feet, we can use the Pythagorean theorem to find the length of the ramp:
ramp length² = base² + height²
ramp length² = 4² + 2²
ramp length² = 16 + 4
ramp length² = 20
Taking the square root of both sides, we get:
ramp length = √20
Simplifying the square root of 20, we get:
ramp length ≈ 4.47 feet
Therefore, the length of the ramp is approximately 4.47 feet.

Which factor could be multiplied by the given function so that their product causes the graph of f(x) to decrease as x approaches negative infinity?
[tex]f(x)=(2x^2 + 5)(x - 7)[/tex]
Select all that apply.
• -3
• 0.2x
• 5x²
• [tex]-\frac{1}{2}(x + 8)[/tex]
• 4(2x - 7)
Answer:
5x²
-1/2( x+8)
Step-by-step explanation:
The dominant term is 2x^2 *x or 2x^3
We want to know what happens when x goes to negative ∞
2 ( -∞) ^3 → 2 * (-∞) → -∞
As long as we multiply by a positive number, we will still be approaching negative infinity ( or decreasing)
-3 is negative
.2x is negative when x approaches negative infinity
.5 x^2 = .5( -∞)^2 = 5 ( ∞) = ∞ which is positive
-1/2 x is the dominant term = -1/2(- ∞) = ∞ which is positive
4(2x) is the dominant term = 8(- ∞) = - ∞ which is negative
Answer:
3rd and 4th Choices.
[tex]\displaystyle 5x^2\text{ and } -\frac{1}{2}(x+8)[/tex]
Step-by-step explanation:
We are given the function:
[tex]f(x)=(2x^2+5)(x-7)[/tex]
And we want to determine the factor(s) that we can multiply to the above function that will cause the graph of f to decrease as x approaches negative infinity.
We can see that the dominant term will be:
[tex]2x^2(x)=2x^3[/tex]
Thus:
[tex]2(-\infty)^3\Rightarrow -\infty[/tex]
It is already decreasing (shifting towards negative infinity) as x approaches negative infinity.
In order to preserve this, then, the factors must be positive as x approaches negative infinity.
The first factor is -3.
-3 is always negative, so it will make f increase.
The second factor is [tex]0.2x[/tex].
[tex]0.2(-\infty)\Rightarrow -\infty[/tex]
This will also make f increase.
The third factor is:
[tex]5(\infty)^2\Rightarrow \infty[/tex]
This is positive, so it will allow f to remain decreasing as x approaches negative infinity.
The fourth factor is:
[tex]\displaystyle -\frac{1}{2}(-\infty+8)\Rightarrow -\frac{1}{2}(-\infty)\Rightarrow \infty[/tex]
This is also positive, so it will also allow f to remain decreasing.
Lastly, the fifth factor is:
[tex]4(2(-\infty)-7)\Rightarrow 4(-\infty)\Rightarrow -\infty[/tex]
This is negative, so it will make f increasing.
Therefore, our answers are the third and fourth choices.

can someone give me the slope and y-intercept for this ?
The slope is equal to the change in y / change in x.
The change in y is always 5 and the change in x is always 1.
So the change in y / change in x is 5/1 or 5.
The y-intercept is the value of y when x = 0.
So the value of y when x = 0 is 2.

A taxi driver had 31 fares to and from the airport last Monday. The price for a ride to the airport is $4.50, and the price for a ride from the airport is $11. The driver collected a total of $289 for the day.
Answer:
(8,23)
Step-by-step explanation:
x+y=31
4.5x + 11y = 289
x = 31 -y
4.5(31 - y) + 11y = 289
139.5 - 4.5y + 11y = 289
6.5y = 149.5
y = 23
x = 31 - 23 = 8
The ordered pair, (x, y) = (8, 23).
What is an ordered pair?
An ordered pair exists as a composition of the x coordinate (abscissa) and the y coordinate (ordinate), containing two values noted in a fixed order within parentheses.
Given: A taxi driver had 31 fares to and from the airport last Monday. The price for a ride to the airport exists $4.50, and the price for a ride from the airport exists $11. The driver collected a total of $289 for the day.
x + y = 31........(1)
4.5x + 11y = 289 ........(2)
From (1), we get
x + y = 31
x = 31 - y
Substitute the value of x in (2), and we get
4.5x + 11y = 289
4.5(31 - y) + 11y = 289
Simplifying the above equation, we get
139.5 - 4.5y + 11y = 289
6.5y = 149.5
y = 23
substitute the value of y, in (1) then we get
x = 31 - y
x = 31 - 23 = 8
The value of x = 8 and y = 23.
Therefore, the ordered pair, (x, y) = (8, 23).
