Which expression represents “add 7 and a number n, then multiply 8 cubed! ? ”

A. Would be your answer

Step-by-step explanation:

7 plus a number n is 7+n, so B and D are already incorrect.

The phrase “and then multiply” suggests parenthesis be around the numbers/variables you would need to do first, so that excludes C.

Making A. your only answer left

Hope I helped!

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
