Consider the function.
f(x)= -2/3x-24
Which conclusions can be drawn about f–1(x)? Select two options.
f–1(x) has a slope of .
f–1(x) has a restricted domain.
f–1(x) has a y-intercept of (0, –36).
f–1(x) has an x-intercept of (–36, 0).
f–1(x) has a range of all real numbers.
Answer:
c and e
Step-by-step explanation:
The conclusions about f⁻¹(x) are ; f⁻¹(x) has a y-intercept of (0, -36) and (e); f⁻¹(x) has a range of all real numbers.
How to determine the conclusions?The function is given f(x) = -2/3x - 24
Express f(x) as y;
y = -2/3x - 24
x = -2/3y - 24
Add 24 to both sides;
x + 24 = -2/3y
Make y the subject,
y = -3/2x - 36
Rewrite
f⁻¹(x) = -3/2x - 36
A linear equation is represented y = mx + b
Where, m represents the slope and b represents the y-intercept
This means :
Slope = -3/2
Y-intercept = -36 or (0,-36)

Diego bought some raisins and walnuts to make trail mix.
Raisins cost $4 a pound and walnuts cost $8 a pound. Diego spent $15 on both ingredients.
Decide if each pair of values could be a combination of raisins and walnuts that Diego bought.
4 pounds of raisins and 2 pounds of walnuts
Answer: You could only buy 1 pound of raisins and 1 pound of walnuts
Step-by-step explanation:
$8=1 pound of walnuts
$15-$8=$7
$4=1 pound of raisins
$7-$4=$3
$3 is not enough to buy a pound of raisins since it’s one dollar off but it is also not enough to buy a pound of walnuts because it’s off by $5
Answer:
4 pounds of raisins and 2 pounds of walnuts is not a solution to this equation.
Step-by-step explanation:
4y+8x=15
4(4)+8(2)=?
4(4)=16
8(2)=16
16+16=32
Therefore, 4 pounds of raisins and 2 pounds of walnuts is not a possible solution for the constraints of the eqution.
Julietta and Jackson are playing miniature golf. Julietta's ball rolls into a long. straight upward incline with a speed of 2.95 m/s and accelerates at -0.876 m/s/s for 1.54 seconds until it reaches the top of the incline and then continues along an elevated section. Determine the length of the incline.
Answer:
3.504 m
Step-by-step explanation:
Given that:
The speed (u)= 2.95 m/s
The acceleration = -0.876 m/s²
TIme t = 1.54 s
The length of the incline can be estimated by determining the distance traveled which can be achieved by using the second equation of motion.
[tex]S = ut + \dfrac{1}{2}at^2[/tex]
[tex]S = 2.95 (1.54) + \dfrac{1}{2}(-0.876) (1.54)^2[/tex]
S = 4.543 - 1.039
S = 3.504 m
Thus, the length of the incline = 3.504 m

A train covers 165 km in 1.5 hours. Find the constant variation.
Answer:
Step-by-step explanation:
110
The required value of constant variation would be 110.
What is the distance?Distance is defined as the product of speed and time.
Direct variation equation can be written as:
y = kx where "k" is a constant variation.
Here y represents the distance covered by the train, and x represents the time duration.
As per the given question,
Since the train covers 165 km in 1.5 hours.
Substitute the values of y = 165 and x = 1.5 in the direct variation equation and solve for k:
⇒ 165 = 1.5k
⇒ k = 165/1.5
Apply the division operation, and we get
⇒ k = 110
Therefore, the required value of constant variation would be 110.

If not, why not? Yes, he is correct. No, he needed to add the exponents when he simplified the powers of the same base. No, he needed to multiply 3 and –1 instead of creating a positive exponent in a fraction. No, his value of (negative 4) squared should be positive because an even exponent indicates a positive value.
Answer:
No, his value of (negative 4) squared should be positive because an even exponent indicates a positive value.
Step-by-step explanation:
The expression is not well written. The expression is written as;
(xy^-2)/(3x²y^-4)
According to indices;
a^m ÷ a^n = a^{m-n}
Applying this to solve the question
1/3(x^{1-2})/(y^-2÷y^-4)
= 1/3(x^{-1})(y^{-2+4})
= 1/3(1/x)y²
= 1/(3x) × y²
Substituting x = 3 and y = -4
= 1/3(1/3)×(-4)²
= 1/9(16)
= 16/9
Imothy solution is incorrect.
According to Imothy solution, his value of (negative 4) squared should be positive because an even exponent indicates a positive value.

Is the point (-2,5) a solution for the equation y = 10 + 4x. Explain why and ensure that math
evidence is in your response.
Answer:
No, the point (-2, 5) is not a solution.
Step-by-step explanation:
To see if the point is a solution, plug the given values for x and y into the equation:
y = 10 + 4x
5 = 10 + 4(-2)
5 = 10 - 8
5 [tex]\neq[/tex] 2
Because the two sides aren't equal to each, the point (-2, 5) can't be a solution.

In golf, shooting par is scored as a 0. A score of 2 below par on a hole in golf is called an eagle. Jacob’s friend Michelle scored an eagle on each of her first five holes. Explain how you would use addition to find the product of –2 and 5 using the integer tiles and the number line. Please help I need this done quick or I get 0 on my test.
If you want to use integer tiles to find the product of 2(-5), think of it as you having 2 groups of 5 negative tiles, that is
-1 -1
-1 -1
-1 -1
-1 -1
-1 -1
Think of it as you having each of the -1 inside it's distinct tile. Now adding up these tiles you have -10.
Therefore 2(-5) is -10 using integer tiles.
If we are to use the number line, first draw your number line, then think of it as jumping twice while each jump is -5 big.
So the first jump from 0 will land on -5 and the second jump will land on -10 and that is the required answer using the number line.
Answer:
sup i know im late but still
Step-by-step explanation:
With integer tiles, you would add 5 groups of negative 2 tiles or remove 2 groups of 5 positive tiles. On the number line, you would bounce by 5 to the left 2 times. - this was the sample response on edge.

What is graph of a function?A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner. The graph of a function f is the set of all points in the plane of the form (x, f(x)).
For the given situation,
A local business can be modeled as function q(x) = [tex]x^2 - 4x + 4[/tex]
x is the price of the item in dollars and
q(x) is the number of items produced at that price.
The graph below shows the function q(x).
From the graph, there are zero items produced at a price of $2, because the x-intercept is at (2, 0).
The number of items produced decreases when the price increases from 0 to 2 dollars.
Hence we can conclude that the answers that complete the statements are a) zero, b) x - intercept, c) 0 to 2 are the correct statements.

find the equation of the line with the slope m= -6 that passes through the point (-3, -5). Write the equation in the form Ax+ By=C
Answer:
y=mx+b
-5= -3(-6)+b
-5=18+b
-23=b
3x-5y=-23
The equation of the line with slope m = -6 that passes through the point (-3, -5) in the form Ax + By = C is 6x + y = -23.
We have,
To find the equation of a line given its slope and a point on the line, we can use the point-slope form of the equation, which is:
y - y1 = m(x - x1)
Where (x1, y1) represents the coordinates of the given point and m is the slope.
Given the slope m = -6 and the point (-3, -5), we can substitute these values into the point-slope form:
y - (-5) = -6(x - (-3))
Simplifying:
y + 5 = -6(x + 3)
Expanding the equation:
y + 5 = -6x - 18
To write the equation in the form Ax + By = C, we need to rearrange it:
6x + y = -18 - 5
6x + y = -23
The coefficients of x and y are 6 and 1 respectively, so the equation can be written as:
6x + y = -23
Therefore,
The equation of the line with slope m = -6 that passes through the point (-3, -5) in the form Ax + By = C is 6x + y = -23.
