8 0

Answer:

-8

Step-by-step explanation:

Multiplying two negatives (or squaring them) cancels the negative, therefore, (-8)^2=64

Best explained and correct answer gets brainliest!!

Semmy [17]

The answer is D, here’s why:

You know the slope-intercept form is y=mx+b
mx being the slope and b being the y-intercept.

y=-4/7x + 9 is already in that form.

A is not the answer because the y is supposed to be by itself.
B is not the answer because again, the y is not by itself.
C is not the answer because the y is also not by itself.

In the slope-intercept form, the y must be by itself and the slope (mx) and the y-intercept must be on the other side.

Hope this helps.

Can someone please please help me on this algebra problem I’m stuck on answering the question?

Rudik [331]

Explanation:

Midline: it is a horizontal line where half of the function above it and half of the function is below it.

Amplitude: It means how far the function varies from the midline to the above and below.

Period: the distance between two consecutive maximum points (minimum points).

3) From the graph,

$\begin{gathered} \text{Midline}=\frac{Maximum\text{ point+ minimum point}}{2} \\ =\frac{3+(-1)}{2} \\ =\frac{3-1}{2} \\ =\frac{2}{2} \\ =1 \end{gathered}$

Answer: Midline=1

1) Amplitude

$\text{Amplitude =}2$

2) Periods

$\begin{gathered} \text{Period}=6 \\ \Rightarrow b=\frac{2\pi}{6} \end{gathered}$

4) The trigonometric equation is,

$\begin{gathered} y=a\cos (b(x-c))+d \\ a=\text{ amplitude} \\ b=\text{period} \\ c=\text{ phase shift} \\ d=\text{ vertical shift} \\ y=2\cos (\frac{2\pi}{6}x)+1 \end{gathered}$

Answer:

$y=2\cos (\frac{2\pi}{6}x)+1$

Step-by-step explanation:

I will assume that the scale factor is 2.5

A'(-5,2.5) True

AB || A'B' True
