Answer:
4/1 or 4
Step-by-step explanation:
when graphing perpendicular lines, the slopes are reciprocals of eachother
If you were supposed to find 40% of $24,850 then the answer would be $9940.
When you multiply a same number but with different powers, you can simply add the powers together. So, in your question, add the powers -1 and -7 together.
7^(-1) x 7^(-7) = 7^(-8)
When you divide a same number but with different powers, you subtract the power at the top with the power from the denominator. So, -8 - (-7) = -1.
7^(-8) / 7^(-7) = 7^(-1)
So your answer would be 7^(-1).
Hopefully my explanation was clear?
A(b-c)=d solution is number 2. Attachment added
They're the same like integers.
First you should interpret it.
For example:
a. -3x + 8x is the same like -3 + 8. You just add x.
Which is 5x.
