Write an inequality for the situation. Use x as your variable. Mrs. Treble charges her music students $25 per lesson plus a recital fee of $30. How many lessons can Melinda take if she wants to pay less than $155?

Inequality: 25x + 30 < 155

Step-by-step explanation:

25x is the cost per lesson. 30 is the recital fee. 155 is the total cost. We used the < sign because she has to pay LESS than $155.

Solve...

25x + 30 < 155

Subtract 30 on both sides...

25x < 125

Divide 25 on both sides...

x < 5

THATS NOT YOUR ANSWER YET Always make sure to plug in the answer you got BEFORE inputting it.

Plug in 5 for x...

25 ( 5 ) + 30 < 155

125 + 30 < 155

155 < 155

You know that she wants to spend LESS than $155, when she takes 5 lessons, as shown above, she spends exactly $155, your answer would be 4 because she spends less than $155 when taking 4 classes, but exactly $155 when taking five.

Really hope this helps! :)

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
