11. the slope of a linear function h(x) is 2. suppose the function is translated 8 units up to get d(x). how can h(x) be translated to the left or right to represent the same function d(x)? explain your answer.

See below.

Step-by-step explanation:

If we translate h(x) to the left it will override  line d(x) because  the slope of both lines is the same. H(x) will need to move 4 units to the left to do this (because the slope =  2 = 8/4).

answer: c

(2, -4)

goes 7 to the

(9, 4)

easy

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
