(Please show work so I can be able to understand it how this works)

Answers

Answer:

x = -1

Step-by-step explanation:

20x - 5(6x + 4) = 4x - 6

20x - 30x - 20 = 4x - 6

-10x - 20 = 4x - 6

-10x - 4x = -6 + 20

4(3+(−3)(−2))−((2)(4))2

Answer:

4

Step-by-step explanation:

First substitute all numbers into the equation:

= 4 ( 3 + ( -3 )( -2 ) ) - 2 ( 4 )^2

Then simply answer the question and evaluate:

= 4 ( 3 + ( 6 ) ) - 2 ( 16 )

= 4 ( 9 ) - 2 ( 16 )

= 36 - 2 ( 16 )

= 36 - 32

= 4

The answer is 4.

Which of the following rules could represent the function shown in the table?
f(x) = -2x
f(x) = 2x-1
f(x) = 2x+1

Answers

Answer: f(x) = 2x+1

Step-by-step explanation: Substitute the variable with the “x” values in the chart to check your answers.

1. f(x) = 2x+1

Add in the “x” value

f(x) = 2x(-1) or 2 multiplied by -1

f(x) = -2 + 1

If the answer is equal to your “y” value , it can represent the function.
