Kylie is wrong about the result since <span>(–4x + 9)2 will result to a perfect square trinomal. Any binomial squared will always result to a perfect square trinomial.
</span>And the expansion of the expression should be
<span>(–4x + 9)2 = </span>(-4x)2 + 2(-4x)(9) + 9^2
(–4x + 9)2 = <span>16x2 - 72x + 18
She missed doing the middle term in doing the multiplication

Step-by-step explanation:
The given expresion is
We want to use synthetic division to find the remainder when the function is divided by x-4.
We write out the coefficient of the function and perform the synthetic division as shown in the attachment.
The remainder is the last number in the last row which is -6.
Answer:
y= 1/3 x +5
Step-by-step explanation:
To find the slope, we take two points
(0,5) and (15,10)
The slope is found by the formula
m = (y2-y1)/ (x2-x1)
= (10-5)/(15-0)
= 5/15
= 1/3
The slope is 1/3
The y intercept is found when x=0
When x=0 y=5
The slope intercept form of the line is
y=mx+b where m is the slope and b is the y intercept
y= 1/3 x +5
