Step-by-step explanation:

y =  \frac{4}{5} x - 3 \\ y =  - 7 \\  - 7 =  \frac{4}{5} x  - 3

- 7 + 3 =  \frac{4}{5} x \\  - 4 =  \frac{4}{5} x \\  - 20 = 4x \\ x =  - 5

4. A video club costs $20 to join. Each video that is rented costs $2.25. Let v represent the number of videos.
shepuryov [24]

Answer:

B.

Step-by-step explanation:

$2.25 is the cost of each video that is rented, so $2.25 times v (or 2.25v) represents the cost of 'v' videos.

$20 is the constant, as it costs $20 to join the club. Since this doesn't change, it is the constant.

So, we would have the equation:

f(v) = 2.25v + 20

f(v) is the total cost.

B is your answer because it is the only one with the correct equation.

Hope this helps!

4(2x-3)+8(x-4)=2(2x+6) help plzzz
TEA [102]

Answer:

x = 14/3

Step-by-step explanation:

4(2x-3)+8(x-4)=2(2x+6)

Distribute

8x -12 +8x - 32 = 4x +12

Combine like terms

16x -44 = 4x+12

Subtract 4x

16x-4x -44 = 4x+12-4x

12x -44 =12

Add 44 to each side

12x-44+44 = 12+44

12x = 56

Divide each side by 12

12x/12 = 56/12

x = 14/3
