$\huge{x = - \frac{5}{4} + \frac{7}{4} y}$
$\huge{x = - \frac{7}{3} + \frac{2}{3} y}$

Step-by-step explanation:

1. $4x - 7y = - 5$

$4x = - 5 + 7y$

$\boxed{\green{x = - \frac{5}{4} + \frac{7}{4} y}}$

$y E R$

○○•○○

2. $3x - 2y = - 7$

$3x = - 7 + 2y$

$\boxed{\green{x = - \frac{7}{3} + \frac{2}{3} y}}$

FinnZ [79.3K]

Answer:

B. Slightly more than $5

Step-by-step explanation:

y = 2x + 3

Firstly we check variables to make sure we understand.

y = dollars

x = pounds

On the scale, it says 1.126 lb. Which means 1.126 pounds.

And so, x = 1.126

y = 2x + 3

y = 2(1.126) + 3

y = 2.252 + 3

y = 2.252

The graph for part a and park b. It is underneath. I wrote 1.1, because it is rounded down from 1.126 lb, which is part b. The one with one line and no dots is part a.
