we know that
if two lines are perpendicular, then the product of their slopes is equal to minus one
so
Step 1
<u>Find the slope of the given line</u>
we have
Solve for y
Divide by 
both sides
the slope of the given line is 
Step 2
<u>Find the slope of a line that is perpendicular to the given line</u>
we have
substitute the value of m1
therefore
<u>the answer is</u>
the slope is 
2 3/8 - 1/4 = 2 1/8 x 1/8 = 17/64.
To do this, you first need to do the problem in the (). You have to turn 1/4 with a denominator of eight, so the fraction becomes 2/8. 2 3/8 - 2/8 = 2 1/8. Now we have to turn 2 1/8 into an improper fraction by doing whole number x denominator + numerator. 17/8 x 1/8 = 17/64.
She spent $75
The best news of this problem is that the books all cost the same.
So 8 + 3 + 4 = 15 books total
15 x $5 = $75
The answer is B(1,-2). This is the only point where the two lines intercept. & if you plug the numbers into the equations they fit.
Answer:
B. Square root
Step-by-step explanation:
using distance formula:
x = √z^2 - y^2
y = √z^2 - x^2
=> z = √x^2 + y^2
