Answer: x = - 1 and y = 0
Step-by-step explanation:
I've attached the answer
The reactangle has an area of x.
So that means two numbers multiplied to each other equal to x. We can just think of itwo numbers that when multiplied equal to x as a and b.
So that means the side lengths are <u />a and b. And ab = x (will be using this right next).
And it was multiplied by some scale factor that made the new area 9x. So if the scale factor is y, then:




y can not equal to -3, because the length of a side of any polygon can never be negative.
So the dilation is 3.And so if the dimension is 5 by 8.
Then the area is

And so then

And then after the dilation, it would be

We could check it another way too. Since we said the scale factor is 3, then:

So
basically
15 by 24 is the new dimensions :)
Answer:

Step-by-step explanation:
We want an exponential function that goes through the two points (0, 8) and (2, 200).
Since a point is (0, 8), this means that y = 8 when x = 0. Therefore:

Simplify:

So we now have:

Likewise, the point (2, 200) tells us that y = 200 when x = 2. Therefore:

Solve for b. Dividing both sides by 8 yields:

Thus:

Hence, our exponential function is:

Answer:
2 with the sqaure root of 12 is = 6.9 simp = 6.9
4 with the sqaure root of 10 is = 12.6 simp= 12.6
sum = 19.5
I hoped this helped! :)
