Answer:

x= $\frac{\sqrt{42} }{3}$

y= -9

Step-by-step explanation:

To solve this problem you need to use substitution. You substitute $y=3x^{2} +5$ into y in $-2x^{2} +y=-5$ and solve for x. Then once you have found the value of x you plug that number into $y=3x^{2} +5$ to find the value of y.

1. Use the given translation rule to find the image coordinates. Rule: (x, y) –(x - 4, y + 3) A(4,6) →A') and B(-2,3) -→B'().O A

artcher [175]

We have to translate the coordinates using the given rule.

The given rule is (x-4,y+3)

Now we have to translate the point A(4,6) using the given rule.

Then,

A' is (4-4,6+3)=(0,9)

Now the point B(-2,3) is to be transformed.

Then,

B' is (-2-4,3+3)=(-6,6)

Hence the answer is A'(0,9) and B'(-6,6)
