Please help me please

42

Step-by-step explanation:

4x + 2 = 1/2 (4x + 44)                Be careful how you do this. I have multiplied both sides by 2

2(4x + 2) = 4x + 44                    Remove the brackets (distributive)

8x + 4 = 4x + 44                        Subtract 4x from both sides

8x-4x + 4 = 44                          

4x + 4 = 44                                Subtract 4 from both sides

4x + 4-4 = 44-4

4x = 40                                       Divide by 4

4x/4 = 40/4

x = 10

The mid line is 4x + 2

The mid line is 4*10 + 2

The mid line is 40 + 2

The mid line is 42

The base is 4x + 44

The base is 4*10 + 44

The base is 40 + 44 = 84 which is twice the midline. I did this just to show it is twice as big as the midline.

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
