Answer: -18=v
Step-by-step explanation: You subtract 8 from both sides. -10-8=-18 which will equal to v.
Answer:
1. x = -7
2. y = -1
Step-by-step explanation:
1.
-3x - 5 = 16 add 5 to both sides
-3x = 21 divide -3 to both sides
x = -7
2.
-4(y-2) = 12 distribute -4
-4y + 8 = 12 subtract 8 from both sides
-4y = 4 divide -4 to both sides
y = -1

1. x = 9
2. y = -3
Answer:
the zero of a function is the value of x which makes the final value zero
First Equation:
So let 25 - 2x equal to 0
<em>25 - 2x = 0</em>
x = 12.5
Second Equation:
Let 2x² - 11x - 6 equal to zero
<em>2x² - 11x - 6 = 0 </em>
<em>2x² - 12x + x - 6 = 0 </em><em>(Splitting the middle term)</em>
<em>2x(x - 6) + 1(x - 6) = 0</em>
<em>(2x + 1) (x - 6) = 0</em>
So we can transpose either one of the brackets below the zero
(2x + 1) = 0 or (x-6) = 0
x = -1/2 or x = 6
Answer:
Step-by-step explanation:
The number of miles that he ran last week is m.
His goal this week was to run one mile more than twice the miles he ran last week. This means that his goal this week is
m + 2m = 3m
If he tripled his goal, it means that the number of miles that he ran this week would be
3 × 3m = 9m
An expression in simplest form to show how many more miles he ran this week compared to last week would be
9m - m = 8m
