castortr0y [4]

Answer:

90$ I'm pretty sure

Step-by-step explanation:

25% of 120=30$, 120-30=90$

To find the answer, you must first convert the sales percentage to a decimal by moving the decimal left two places.

20%=0.20

Then, multiply the total cost by the decimal.

$15.98(0.20)=$3.19

This gives us the amount of the discount. To find the remaining cost, we subtract that number from the original cost to get the answer.

$15.98−$3.19=$12.79

Step-by-step explanation:

an equation is :  y = 10x+b

calculate b : this line passes by : (7;1) when x =7  y = 1

b= -69

What is the slope of 1.5x+4.5y=18
melomori [17]

Answer:

The x intercept is (12,0)

Step-by-step explanation:

1.5x+4.5y=18  Subtract 1.5 x from both sides of the equation

4.5y=-1.5x+18  Divide both sides of the equation by 4.5

4.5y/4.5=-1.5x/4.5+18/4.5

y=-1/3x+4

The slope is -1/3

The y intercept is (0,4)

To find the x intercept, yet y=0 and solve.

1.5x+4.5y=18

1.5x+4.5(0)=18

1.5x=18  Divide both sides of the equation by 1.5

1.5x/1.5=18/1.5

x=12
