Answer:
from what i can tell this seems to be a translation three units down and three units to the left, this is not a dilation
Step-by-step explanation:
It would be (x+2)(x+2) factored
and use the distribution property if u want to solve it
x^2+2x+2x+4
=x^2+4x+4
So your starting amount is 5. Your equation will start like this:
5+
Now 45 dollars a week. So no matter how many weeks you are going to multiply it by 45. So you add that in and you have an equation that looks like this:
5+45x
X stands for the weeks. Then finish it off with your equals:
5+45x=y
Y is the total amount of money.
The Equation will be.
5+45x=y
Part 2:
The equation is set up on weeks so you need to find out how many weeks 28 days is.
28/7=4
Now that you know that you can substitute 4 for x.
5+45*4=y
5+180=y
185=y
He will have 185 dollars in his bank. <span />
Answer:
80%
Step-by-step explanation:
1/8 is only 0.125 and 80% is 0.8
We know that 8/75 patients prefer bubblegum toothpaste. We want to make the ratio, “_:1500”. To do this, we divide 1500 by 75 to get 20. The ratio is now p : 1500. Now, we must do the same thing on both ends: since 75 times 20 got us 1500, 8 times 20 gets us 160. So, 160 out of the dentist’s 1,500 patients prefer bubblegum toothpaste.
