Answer:
a. y = 3x + 4.5 & y = 7x + 2
b. x = 0.625 (year)
c. 6.375 feet
Explanation:
Type A starts at 4.5 and Type B starts at 2 ,each year can be marked as x
type A grow 3 inches per year = 3x
type B grows 7 inches per year = 7x
y = the total height
Since they both equal to y, you can set them equal to each other
3x + 4.5 = 7x +2
After solve you get answer for b
Work: 3x + 4.5 = 7x + 2
4.5 = 4x + 2
2.5 = 4x
0.625 = x
Substitute the value of x you got from part b into each equation then you will get 6.375 as your y value which is also your height
Answer:
20
Step-by-step explanation:
Why? because 100$ in 5 days is he spent the same much each day then it's 20 because 20 x 5=100
