Answer:

slope = 6

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2.5, - 24) and (x₂, y₂ ) = (4.75, 19.5)

m = \frac{19.5+24}{4.75+2.5} = \frac{43.5}{7.25} = 6

Answer:

C = 8

Step-by-step explanation:

Rearrange the equation to make C the subject.

C - 12 = -4

Add 12 to both sides.

C - 12 + 12 = -4 + 12

C = -4 + 12

C = 8

Check it:

C = 8

So substitute the new found value into the original equation:

C - 12 = -4

8 - 12 = -4

-4 = -4

All good.

anyanavicka [17]

Answer:

Option B. 5 hours

Step-by-step explanation:

The tennis club charges monthly fees = $50.00

and per hour charges of court time = $10.00

Lets assume you play number of hours in a month = x hr

So, per hour charges would be = $10x

Total payment = monthly charges + charges of played hours

$100.00 = $50.00 + 10x

10x = 100 - 50

10x = 50

x = 5

Option B. You used 5 hours court time.

A furniture store has a sale during which the sale price of a sofa is 1/3 off its original price. The original price
dmitriy555 [2]

Answer:

$694.06

Step-by-step explanation:

OG price= 1,029

discount=.05

sales tax =.065

1/3(og price)=1/3(1029)=343

one third of $1,029 is 343, hence we take off $343 from the orginial price

1029-343= $686--> sales price

.05*salesprice= .05*686=34.3

subtract 5% discount: 686-34.3= $651.71

=find 6.5% tax: .065*651.71= $42.36

add 6.5% tax:  651.81+42.36=694.06
