Answer:
f(2h) = -4h + 9
Step-by-step explanation:
Jacob: Start with the given function f(x) = -2x + 9 and replace 'x' with 2h:
f(x) = -2x + 9 becomes:
f(2h) = -2(2h) + 9, or
f(2h) = -4h + 9
Answer:
-4h + 9
Step-by-step explanation:
f(x) = -2x + 9
f(2h) = -2(2h) + 9
f(2h) = -4h + 9

write the equation (y=kx)
= kx. where k is the constant of variation. Since k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3.
Simply so, which graph represents an equation in the form y KX?
Slope of y = kx Theorem The graph of the direct-variation function with equation y = kx has constant slope k. Now solve this system of equations for k. So by the definition of slope, k is the slope of the line through these points. Thus, k is the slope of the line with equation y = kx.
Also, which statement is always true about the graph of an equation in the form y KX Y KX? The equation y = kx is a proportional graph. It means that you multiply x by a number and you have k. The point (0, 0) will always be on the graph, because no matter what K is, if you are multiplying by 0 for x, you will get 0 for y.
Secondly, what is Y KX called?
In the equation y = mx + b, if m is a nonzero constant and b = 0, then you have the function y = mx (often written y = kx), which is called a direct variation. In this function, m (or k) is called the constant of proportionality or the constant of variation.
What is direct variation?
Direct Variation. Directly Proportional. A relationship between two variables in which one is a constant multiple of the other. In particular, when one variable changes the other changes in proportion to the first. If b is directly proportional to a, the equation is of the form b = ka (where k is a constant).

Answer:
Actually it seems like there is an error (in my opinion)
Step-by-step explanation:
The first option shows Distributive property which cannot be categorised as associative property.
The third option seems right as associative property however on the R.H.S there is a 9, which is unneeded. So, the answer is a and c.

a line has a slope =6 and passes through the point (3,7). write the equation from point slope form to standard form.
Answer:
[tex]y = mx + c [/tex]
[tex]7 = 6 \times 3 + c[/tex]
[tex]7 = 18 + c[/tex]
[tex]7 - 18 = 18 - 18 + c[/tex]
[tex] - 11 = c[/tex]
[tex]y = 6x + - 11[/tex]
[tex]y = 6x - 11[/tex]
A rectangle has a perimeter of 36 cm. Its width is 4 cm less than its length. Find
the length and width of the rectangle.
Answer:
14
Step-by-step explanation:
Perimeter = 2 x length + 2 x width = 2L + 2w
Width is 4 cm less than the length, so w = L-4
36 = 2L + 2(L-4)
36 = 2L + 2L - 8
36 = 4L - 8
44 = 4L
L = 11
w = 7
2(11) + 2(7) = 22 + 14 = 36
Length is 11, width is 7

Sandra drove 117 miles in an hour and 30 minutes to visit her son at college, without stopping. If the speed limit is 60 mph, explain why she should or should not get a speeding ticket. Make sure to include mathematical computations in your answer.
Answer:
She should get a speeding ticket. The speed limit is 60mph and her speed was 78 mph, 18 miles over the speed limit.
Step-by-step explanation:
She drove 117 miles in 90 minutes.
117/90 = 1.3 miles per minute
1.3 miles x 60 minutes = 78 mph

Examine the following table of points, which are all on a certain line.
x y
−2 4
0 2
1 1
3 −1
Answer: I don't see a question, but the equation of the line that these points form is y = -x + 2
Step-by-step explanation:
y=-x+2
The points have a negative 1 as their slope. The y-intercept (the value of y when x=0) is 2
y = -x+2

A recipe for 10 bran muffins calls for 1 cup of flour. The number of muffins that can be made varies directly with the amount of flour used. There are 3 1/2 cups of flour available. How many muffins can be made?
Answer:
35
Step-by-step explanation:
3 1/2 x 10 =35
make 3 1/2 into an improper fraction: 3 x 2 + 1 = 7/2
make 10 into a fraction: 10/1
find the LCD (least common denominator) for each number:
10/1 = 20/2
7/2 = 7/2
20/2 x 7/2 = 70/2 = 35
:)
Answer:
35
Step-by-step explanation:
For 1 cup of flour, you make 10 muffins. Just by reading the problem, you see that the number of muffins, 10, is 10 times the number of cups of flour, 1.
For 3 1/2 cups of flour, you make 10 times that number muffins.
3 1/2 × 10 = 3.5 × 10 = 35
Answer: 35 muffins
You can also use a proportion.
1 cup flour is to 10 muffins as 3.5 cups flour is to x muffins.
1/10 = 3.5/x
Cross multiply:
1 × x = 10 × 3.5
x = 35
Answer: 35 muffins
Which statement best explains whether △JKL is congruent to △MNP?
Answer:
D.
Step-by-step explanation:
The triangles are congruent, and the correct answer is D.
D. △JKL is congruent to △MNP because △JKL can be mapped to △MNP by a rotation of 180° about the origin followed by a translation 2 units up.
Rotation of triangle JKL by [tex]180^{o}[/tex] will result in the triangle with corresponding vertices of (2, 4), (3, 2) and (-1, 2).
so translating the resulting triangle two units up will result in the triangle with corresponding vertices (4, -2), (2, -3) and (2, 1) which is the same triangle like the given triangle MNP.
Which best explains why the figures are congruent?The figures is congruent because the 270° rotation about the origin or then the reflection over the x-axis would mapped ΔABC into ΔLMN.

PROBLEM SOLVING A water sample must be taken from water at least 20 feet deep. Find the depth of the water 50 feet
from shore.
50 ft
5 ft
21.5t
d
Not drawn to scale
The depth is
feet.
Is this an appropriate location for a water sample?
Using the principle of similar triangles, the appropriate depth to take the water sample should be 15 feets
Setting up the equation thus :
1.5 / d = 5 / 50
Cross multiply
1.5 × 50 = d × 5
75 = 5d
Divide both sides by 5
5d / 5 = 75/5
d = 15
Therefore, the appropriate depth to take the water sample is 15 feets.
