Answer:
Your answer is x = 1
Step-by-step explanation:
First start by distributing 5 to everything in the parenthesis.
5 * 2x = 10x
5 * -8 = -40
What you're left with is 10x - 40 + 15 = -15
Next subtract 15 from both sides.
10x - 40 + 15 - 15
The 15's will cancel each other out on the left side.
-15 - 15 = -30
What you're left with is 10x - 40 = -30
Next add 40 to both sides.
10x - 40 + 40
The 40's will cancel each other out on the left side
-30 + 40 = 10
What you're left with is 10x = 10
Divide both sides by 10 to get x by itself.
10x / 10 = x
10 / 10 = 1
What you're left with is x = 1

Answer:
- 3
Step-by-step explanation:
Differentiate f(x) using the power rule
(a
) = na
Given f(x) = 
= 3
, then
f'(x) = - 3
= - 
f'(1) = - 
= - 3
Answer:
C) Subtraction property of equality.
Step-by-step explanation:
Given that, two lines 
and 
intersect to make pairs of vertical angles:
and 
.
Kindly refer to the attached image for details of the given angles and lines.
Proof that 
:
Here, subtraction property of equality is used in the last step shown in the above.
As per the <em>Subtraction property </em>of equality, when some value is subtracted from both the sides of the equality, equality remains the same.
