Perpendicular = opposite sign and reciprocal slope
Make equation into y = mx + b
Add 3y to both sides
3y + 54 = 3x
Subtract 54
3y = 3x - 54
Divide by 3
y = x - 18
The slope is 1
Make it negative and reciprocal
= -1/1 = -1
Solution: the slope will be -1
Answer:
1.5
Step-by-step explanation:
Answer:
56 square units
Step-by-step explanation:
The formula for the area of a triangle of base b and height h is:
A = (1/2)(b)(h)
Here, that area is A = (1/2)(8)(14) = 56 square units
Answer:
x = 14
Step-by-step explanation:
Given
-
(x - 4) = - 2
Multiply both sides by 5 to eliminate the fraction
- (x - 4) = - 10 ← distribute parenthesis by - 1
- x + 4 = - 10 ( subtract 4 from both sides )
- x = - 14 ( multiply both sides by - 1 )
x = 14
