Answer:

2 times 2 times 2 times 5

Step-by-step explanation:

You can work this out using elimination. 2 X 2 X 4 X 5 = 80. So you immediately know it isn't that one

2 X 20 is a possible answer because it equals to 40 however the 20 is still there meaning that wouldn't work.

2 X 5 = 10 So that would work either

PLEASE HELP NEED THIS TO PASS

The solutions to f(x) = 64 is x = 7 and x = –7.

Solution:

Given data:

$$f(x)=x^{2}+15$ – – – – (1)

$f(x)=64$ – – – – (2)

To find the solutions to f(x) = 64.

Equate equation (1) and (2), we get

$x^2+15=64$

Subtract 15 from both sides of the equation.

$x^2+15-15=64-15$

$x^2=49$

$x^2=7^2$

Taking square root on both sides of the equation, we get

x = ±7

The solutions to f(x) = 64 is x = 7 and x = –7.

Graph the line with slope 7 and y-intercept -7

poizon [28]

Given :-

To graph the line with slope 7 and y intercept -7.

To Find :-

The graph of the line .

Solution :-

Here since the slope of the line is 7 and y intercept is -7 , we can use the slope intercept form of the line to find the equation of the line . The slope intercept form of the line is ,

$\longrightarrow$ y = mx + c

On putting the respective values ,

$\longrightarrow$ y = 7(x) + (-7)

$\longrightarrow$ y = 7x - 7

For the graph see attachment .
