The correct answer is 3.

A linear relationship is when a set of numbers increases by a specific amount.

In these columns, the first, second, and third columns are each increasing by the same amount, whereas in the fourth column, the numbers increase by varying amounts.

She worked 9 hours at baby-sitting and 6 hours at her parents store.

Step-by-step explanation:

Let,

Baby-sitting hours = x

Hours at parents store = y

Total hours = 15

Amount earned = $93

According to given statement;

x+y=15 Eqn 1

5x+8y=93 Eqn 2

Multiplying Eqn 1 by 5;

$5(x+y=15)\\5x+5y=75\ \ \ Eqn 3\\$

Subtracting Eqn 3 from Eqn 2;

$(5x+8y)-(5x+5y)=93-75\\5x+8y-5x-5y=18\\3y=18$

Dividing both sides by 3;

$\frac{3y}{3}=\frac{18}{3}\\y=6$

Putting y=6 in Eqn 1

$x+6=15\\x=15-6\\x=9$

She worked 9 hours at baby-sitting and 6 hours at her parents store.

Solve the following equation for y<br> 1/2x+y=24<br> what is y?

Basile [38]

Answer:

y=-1/2x+24

Step-by-step explanation:

you solve for y by isolating the y on one side of the equation and the rest of the equation on the opposite side of the equal sign.

1/2x-1/2x+y=24-1/2x

y=24-1/2x

rewritten: y=-1/2x+24
