Answer:
Step-by-step explanation:
Perimeter = 2*(length + width)
=2*(-3x +4 + 5x - 2)
=2*(2x + 2)
=2*2x + 2*2
=4x + 4
Answer: B
Step-by-step explanation:
Domain is x values
Range is y values
Domain you look from left to right. You can see it starts at -3, and it goes all the way to 2. NOT 4 BUT 2!! Since we are looking at the X.
Range.. WE ARE LOOKING AT THE LOWEST POINT!! LOWEST POINT FIRST!1 I cannot stress enough. The lowest y-value is -2, and it's maximum point is 4!
REMEMBER:
DOMAIN = X LEFT TO RIGHT
RANGE= Y LOWEST POINT TO HIGHEST
First, you need to know how much they’re dilated.
To find that out you do:
15/10 = 1.5
So they’re dilated by 1.5cm
To find the value for y you do:
6•1.5 = 9
y = 9
