How do you check? -5r+-3=51

Mathematics
1 answer:
Varvara68 [4.7K]3 years ago
5 0

-5r + (-3) = 51

Add 3 to both sides:

-5r = 54

Divide both sides by -5 to get r alone:

r = -10.8

To check this, plug in -10.8 into the equation: -5(-10.8) + (-3) = 51

54 + (-3) = 51

54 - 3 = 51

51 = 51

This statement is true, so the answer is correct.

What is the y-intercept of the graph of 4y = 2x + 8?<br> 4<br> 2<br> 6<br> 00<br> N
Jet001 [13]

Answer:

2

Step-by-step explanation:

4y = 2x + 8

First get the equation in slope intercept form  y= mx+b where m is the slope and b is the y intercept

Divide each side by 4

4y/4 = 2x/4 +8/4

y = 1/2x +2

The slope is 1/2 and the y intercept is 2
