Answer:

One solution

Step-by-step explanation:

They have isolated y for you in both equations so you can plug either one into the other.

y = 3x - 1

2x + 7 = 3x - 1

isolate the x

7 = x - 1

x = 8

Go back to the original and plug 8 into x to get y.

y = 2 (8) + 7

y = 16 + 7

y = 23

This means at (8, 23) y = 2x+7 is equal to y = 3x-1. In other words they share a point at (8, 23). This is the only solution because for any other x and y they'd not be equal.

Della by tree seedling that was 2 1/4 feet tall during the first year it grew 1 1/6 ft after two years it was 5 ft tall how much
jasenka [17]
<h2>Greetings!</h2>

Answer:

\frac{19}{12} feet

Step-by-step explanation:

First, we need to find the height after one year:

2.25 + 1 1/6 = \frac{41}{12}

Now to find the amount in the second year, we can subtract the above amount from 5:

5 - \frac{41}{12} = \frac{19}{12}

So in the second year it grew \frac{19}{12} feet
