Answer:

X= -44

Step-by-step explanation:

Multiply parenthesis by 2. Distribute 2 through the parenthesis. Collect like terms. Calculate the difference. Move variable to the left side and change it's sign. Move constant to the right side and change it's sign. Collect like terms. Add the numbers. Change the signs on both sides of the equation. Then you'll get X= -44

Answer:

44/7

Step-by-step explanation:

First, carry out the indicated multiplication, using the Distributive Property of Multiplication:

-4x + 2(3x – 1) - 12 = 3x + 30 becomes:

-4x + 6x – 2 - 12 = 3x + 30

Next, combine all the x terms and all the constants.  We get:

10x - 14  = 3x + 30, or 7x = 44

Dividing both sides by 7 yields x = 44/7.

Answer:

Gym A

Step-by-step explanation:

A linear relationship is a relationship of the form y = mx + b, where y and x are the linear variables, m is the rate of change and b is the value of y when x = 0.

Gym A:

Let x represent the month and y represent the total cost for the gym. From the table, we can represent the values in the form (x, y) as (1,70), (2, 90) and (3, 110). We can find the relationship between x and y using the formula:

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\Let \ us\ use\ the\ points\  (1,70)\ and\ (3,110),hence:\\\\y-70=\frac{110-70}{3-1}(x-1)\\\\y-70=20(x-1)\\\\y=20x-20+70 \\\\y=20x+50\\\\For\ 10\ months(i.e.\ x=10):\\\\y=20x+50\\\\y=20(10)+50\\\\y=\$250

Gym B:

We can represent the values from the table as (1,55), (2, 80) and (3, 105). We can find the relationship between x and y using the formula:

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\Let \ us\ use\ the\ points\  (1,55)\ and\ (3,105),hence:\\\\y-55=\frac{105-55}{3-1}(x-1)\\\\y-55=25(x-1)\\\\y=25x-25+55 \\\\y=25x+30\\\\For\ 10\ months(i.e.\ x=10):\\\\y=25x+30\\\\y=25(10)+30\\\\y=\$28 0

Hence gym A would cost less ($250 < $280)
