Answer:
w = - 15
Step-by-step explanation:
Assuming you mean
= - 4 ( multiply both sides by 3 to clear the fraction )
w + 3 = - 12 ( subtract 3 from both sides )
w = - 15

Answer:
The answer to your question is these lines are not perpendicular.
Step-by-step explanation:
Data
A (4, 2)
B (-1, 4)
slope = m = 4
Perpendicular lines mean that these lines cross and form an angle of 90°. Also, the slope of perpendicular lines is negative reciprocals.
Process
1.- Find the slope of the second line and compare it to the slope given.
slope =
Substitution
slope =
Simplification and result
slope =
-2/5 is not a negative reciprocal of 4, so these lines are not perpendicular.
Answer:
B) Multiply each side by 3
Step-by-step explanation:
This is how to solve for h
+ 7 = 5 (First Step --> Subtract 7 from both sides)
= - 2 (Second Step --> Multiply both sides by 3 to cancel out the denominator and to find just h)
h = -6
