Answer:

Step-by-step explanation:
To make this a bit easier to see, we'll expand that expression.
R to the 9th is just r times itself 9 times. R to the third is r times itself 3 times.
(excuse my bad formatting)
<u>The expression:</u>
<u>r • r • r • r • r • r • r • r • r • 1</u>
r • r • r • 1
Remember, anything and everything has a coefficient or denominator of 1.
So, we can cancel 3 r's from the numerator and denominator.
<u>r • r • r • r • r • r • 1</u>
1
Simplify....

That just equals
.
your answer is 30
1^2 (raised to the power of 2) +2 is 3
5^2 +2 is 27
5^2=25
1^2=1
add 27+3=30
Y=2x-3 rise over run and then the y intercept
Answer: 45
Step-by-step explanation: j/9=5. Multiply both sides by 9: j=9×5=45. So j is 45.
Answer:
x≥−3
Step-by-step explanation:
−4x−10≤2
Step 1: Add 10 to both sides.
−4x−10+10≤2+10
−4x≤12
Step 2: Divide both sides by -4.
−4x−4≤12
−4
x≥−3
