Answer:

Step-by-step explanation:

because -3 is a zero, so x=-3

(k-1)(-3)²+k(-3)+1=0

9(k-1)-3k+1=0

9k-9-3k+1=0

6k=8

3k=4

k=4/3

(B)

∵ x=-1 is a zero of p(x)=kx²-4x+k

so k(-1)²-4(-1)+(-1)=0

k+4-1=0

k=-3

Whether the dilation is an enlargement or a reduction?

melomori [17]

The equation is a reduction

it’s scale factor is 1/ 2

an algebraic representation for the dilation is written as (x, y) -> (kx, ky), with k being the variable for the scale factor

(2, 6) -> (1/ 2 • 2, 1/ 2 • 6)

Answer:

$4(x^{2} -4)^{2} -76$

Step-by-step explanation:

Take out 4:

4(x^2-8x)-12

=4(x^2-8x+16-16)-12

=4(x^2-8x+16)-64-12

=4(x^2-4)^2 - 76

= $4(x^{2} -4)^{2} -76$

How do you answer this equation?<br> 5a - 12 = 48

IgorC [24]

Add 12 to both sides resulting in 5a = 60 and then divide both sides by 5 which results in a = 12 so your answer will be a = 12

Given: 8x-61=17, prove: 39/4

Degger [83]

Answer:

The solution is $x = \frac{39}{4}$

Step-by-step explanation:

We are given the following equation:

8x - 61 = 17

We want to find the solution, that is, the value of x. So

$8x - 61 = 17$

$8x = 78$

$x = \frac{78}{8}$

Simplifying by 2

$x = \frac{39}{4}$

The solution is $x = \frac{39}{4}$
