Answer:
4
Step-by-step explanation:
Input -4 into the equation which comes out to
-3 * (-4) - 8
Which equals 4
Answer:
x = 4 and the expression when evaluated at x = 4, is 16.
Step-by-step explanation:
For this problem, we will simply look at the wording of the question and the given expression. The question ask, "What would x be equal to if x equaled 4 in this: 4x?"
In the problem, we are already given that x = 4 in the following expression, so the answer to the question is x = 4. If we were to evaluate the expression when x = 4, we would say the following:
If x = 4, then:
4x
= 4(4)
= 16
Hence, the expression would be 16 if evaluated when x = 4.
Cheers.
The equation is 4x+8=-12 so you subtract 8 from both sides to give you 4x=-20, then you divide by 4 to get x=-5
Answer:
2
Step-by-step explanation:
A coefficient is the number placed before the variable. The variable gets multiplied by the coefficient.
The format is not exactly clear with the expression in the question.
Assuming the expression is '8 * 2n', the coefficient would be 2.
'n' is getting multiplied by '2'.
'8' does not have a variable next to it, so it is just a term in the expression.
The product of 8 and 2 is 16. 16 is not in the expression.
If the expression was '8.2n', 8.2 would be the coefficient.

Plug in the numbers
2 = 3(2) - 4, true
-4 = 3(0) - 4, true
8 = 3(4) - 4, true
-1 = 3(-1) - 4, false
Solution: D
