Answer:
Step-by-step explanation:
Perpendicular lines are lines whose slopes are negative reciprocals of each other
To find the slope of the line we are given, we can rearrange the equation

The slope of this line is
, so the slope of the other line is 
next, we can use the given point to find the equation 
we know m, we can solve for b



Answer:
A
Step-by-step explanation:
The ratio is
1 inch : 100 miles
0.5 inch : X miles
1/100 = 0.5/X
X = 0.5 ÷ 1/100
X = 0.5 × 100/1
X = 50
9 = 3^2
Since 3 squared equals 9, that is how 9 as a power of the base 3 should be written.
Answer:

Step-by-step explanation:
Given
x² - 3x
To make the expression a perfect square
add ( half the coefficient of the x- term )²
x² + 2( -
)x +
, thus
x² - 3x + 
= (x -
)² ← a perfect square
The answer is C.
