because you replace n with 7
Answer:
-x + 4
Step-by-step explanation:
(4x+5)+(−5x−1)
4x+5−5x−1 [Remove the parentheses]
-x + 4 [Combine Like Terms]
Answer:
C) 14
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.
Multiply -2 to both sides of the equation. Note that, when multiplying two negative numbers, your outcome will be positive:
(-2)((-1/2)x) = (-7)(-2)
x = -7 * -2
x = 14
C) 14 is your answer.
~
y = mx + b
m= 1/2 Then y = 1/2(x) + b
Calculate b
3 = 1/2.(4) + b
3 = 2+b and b = 1
Final equation y = 1/2(x) + 1
Answer:
Should be B
Step-by-step explanation:
5 + 2 ( x-4[3x+7(2-x)]
5+2 (x-4[ 4x + 14])
5+2 (17x - 56)
5 + 34x - 112
34x - 107
