Well A.Given Information B. Postulates D.A Theorem That has already been proven Are all Right Except C.
It is best to make a table for this one
Hour | Cells
0 | 1
1 | 2
2 | 4
3 | 8
4 | 16
5 | 32
6 | 64
7 | 128
After 7 hours, there are 128 cells. To find this, you multiply the starting amount by two each hour.
Answer:

Step-by-step explanation:
If the slope of a line is 4/3,
and we wanna find the equation of a line that is parallel to it and crosses through (5,5).
So we already have the slope because the slope of 2 parallel lines are the same.
y = 4/3x
Look at the image below↓
So now we just need to find the y-intercept.
After some numbers we got,

Look at the other image below↓
<em>Thus,</em>
<em>the equation of the parallel line is </em>
.

Answer:
a = 49 - the height of the tallest water slide
b = 49 + 5 - the height, in meters, of the slide Phineas and Ferb want to build
c = (49 + 5) / 6 - number of sections needed to meet their goal
hope this helps! <3
