13.) A=9cm^2
If the area is l•h, and there are 9 cubic squares, that means that the length of each side on the square is 3cm, each square on it equals 1cm.
14.) V=27cm^3
If the volume is l•w•h, then we find the third power square root of 27, so 3•3=9•3=27, the answer is 3cm for the length, width, and height.
15.) V=4,913cm^3
If volume is l•w•h, then what number when raised to the third power equals 4913? The answer is 17, since 17•17=289•17=4913. So the length is 17cm
16.)V=216cm^3
If volume is l•w•h, then what number when raised to the third power equals 216? The answer is 6, since 6•6=36•6=216.
17.)A=121
Is area is l•w, then what number raised to the second power equals 121? The answer is 11, since 11•11=121. Therefore it WILL NOT fit a car with a length of 13ft.
18.)A=141
If area is l•w, then what number raised to the second power equals 141? The answer is 12, since 11.87•11.87=141 (answer was rounded to nearest whole number) meaning that she will need 12ft of fence to enclose her garden.

Cant remember how to do this :( Please help !!​
Juli2301 [7.4K]

Answer:

B

Step-by-step explanation:

1) Look at the y-intercepts.

The y-intercepts on both equations are the same: 5. That means both equations touch the y-axis at (0,5).

That means we can rule out both A & C.

2) Calculate the rate of change (a.k.a. slope) of f(x).

To do this, we must use two points to find the change of y over the change of x. From the graph, we can use the points (1,2) and (2,-1).

Δy / Δx = \frac{-1 - (2)}{2-1} = \frac{-3}{1} = -3

<em>*The little triangles are the Greek symbol delta. They mean change in...*</em>

That means that the slope of f(x) is -3.

3) Figure out the rate of change (a.k.a. slope) of g(x).

To do this, all we have to do is look at the equation. It is written in y = mx + b format where m = slope and b = y-intercept. That means the slope is 5 as in place of "m" there is a 5.

4) The Answer

The answer is B because 5 [the rate of change for g(x)] is greater than -3 [the rate of change for f(x)].
