<h3>
Answer: y = -x-2</h3>
==================================================
Explanation:
First we need the slope

Then we can find the y intercept using the coordinates of (x,y) = (-4,2)
y = mx+b
2 = -1(-4)+b
2 = 4+b
2-4 = b
-2 = b
b = -2
Alternatively, you can use the other point (x,y) = (3,-5) and m = -1.
Because m = -1 and b = -2, we go from y = mx+b to y = -1x+(-2) which simplifies to y = -x-2
Answer:
D
Step-by-step explanation:
If you rotate, translate, or reflect a figure, the afterimage will be congruent to the original.
But if you dilate the figure, you are changing the dimensions and the length of its sides. However, angle measures are preserved and therefore that makes the figure and its afterimage similar.
Therefore C.) produces a similar but not congruent figure because there is the dilation in it.

Step-by-step explanation:
f*g= f(x) and g(x)
i.e, f*g= (x^2+3x-4)(x+4)
i.e, f*g= x^3+3x^2-4x+4x^2+12x-16
i.e, f*g=x^3+7x^2+8x-16
it's domain is R, i.e, all real number!
f/g=(x^2+3x-4)/(x+4)
i.e, f/g={(x+4)(x-1)}/4
i.e,f/g=x-1
it's domain is all real number,except the number at which (x+4) becomes 0, i.e, x= (-4), -4 is not in domain!
