Answer:
(1) 9n = 56
<u>n = 6</u>
(2) 10 + 4y = 38
<u>y = 7</u>
(3) 3x + 8x = 55
<u>x = 5</u>
(4) 6m + 20 = 8
<u>m= -2</u>
(5) 17 - 3a = 23
<u>a = -2</u>
(6) 10x + 4 = 6x + 16
<u>x = 3</u>
(7) 4(x - 2) + x = 17
<u>x = 5</u>
(8) 2(x + 3) + 3x = x + 22
<u>x = 4</u>
(9) <u>D. 10</u>
(10) -2(3x - 2.4) = 3(3x - 2.4)
im not sure about this equation
<em>Hope this helps</em>

Answer:
f'(x) = -f(x) = 9xy² - 6x²y + 5x³
Step-by-step explanation:
f(x) = –9xy² + 6x²y – 5x³
additive inverse: f'(x) = -f(x) = 9xy² - 6x²y + 5x³
f(x) + f'(x) = f(x) -f(x) = (–9xy² + 6x²y – 5x³) + (9xy² - 6x²y + 5x³) = 0
4x(-2) + 4 x 7 4x5 + 2x(-1) =[-8 20]
[28 -2 ]
Answer:
The simplified form would ve -19 - 4x
Step-by-step explanation:
Before we combine anything, we first must expand the expression by distributing the -3 to the terms in the parenthesis.
-7 - 3(4 - 2x) - 10x
-7 - 12 + 6x - 10x
Now we can combine the terms with and without variables.
-19 - 4x
