First convert the feet to inches:

3 feet= 36 in.; 4 feet=48 in.

Make an equation for each one:

Type A: h=36+15x

Type B: h=48+10x

Since the questions wants the heights to be equal, h=h so you can substitute so you have:

36+15x=48+10x

5x=12

x=2 2/5 years or 2.4 years

Please help I will give brainliest IF IT IS CORRECT

Andreyy89

Answer:

third graph and (3, -1)

Step-by-step explanation:

y = 2/3x - 3

y = -2x + 5

2/3x - 3 = -2x + 5

2 2/3x = 8

8/3x = 8

8x = 24

x = 3

find 'y'

y = -2(3) + 5

y = -1

The third graph is correct because it shows both a line intersecting the y-axis at -3 and the negative slope line is crossing at +5
