For functions, x’s can’t repeat, so looking at the first problem, C is the only one where the first number in each coordinate (x,y) doesn’t repeat.


For the second, x = -2 means that no x is always -2 matter which y you would look at. So x’s repeat and it forms a vertical line. So it is not a function

Find the value of x in the number (2x-15), (x-5), and 148 degrees
Mandarinka [93]

Answer:

Simplifying

2x + -15 + x + -5 = 148

Reorder the terms:

-15 + -5 + 2x + x = 148

Combine like terms: -15 + -5 = -20

-20 + 2x + x = 148

Combine like terms: 2x + x = 3x

-20 + 3x = 148

Solving

-20 + 3x = 148

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '20' to each side of the equation.

-20 + 20 + 3x = 148 + 20

Combine like terms: -20 + 20 = 0

0 + 3x = 148 + 20

3x = 148 + 20

Combine like terms: 148 + 20 = 168

3x = 168

Divide each side by '3'.

x = 56

Simplifying

x = 56
