sorry, i have to keep looking back at the photo
for the last question i will be solving ok
Answer:
I need to see the equation
Answer:
definantly 3/2
Step-by-step explanation:
perpendicular means same slope
Answer:
x = -9
x = 2
Step-by-step explanation:
Given:

First, note that

Since
and
stay in the denominator, then

Now add two fractions which stay in the left part. The common denominator is
so multiply the numerator of the first fraction by
and the numerator of the second fraction by
and subtract them in the numerator:

With 10 spots between each 1/10th, the equation for each space would be
(1/10)/10
(Simplify)
1/10*10
1/100
FRACTION: 13/100
DECIMAL: 0.013
