<u>Answer:</u>
r = 
<u>Step-by-step explanation:</u>
Multiply both sides by r + 120.
<em>t </em>(<em>r </em>+ 120) = 120<em>r</em>
Expand.
<em>tr </em>+ 120<em>t </em>= 120<em>r</em>
Subtract <em>tr</em> from both sides.
120<em>t </em>= 120<em>r </em>- <em>tr</em>
Factor out the common term <em>r</em>.
120<em>t </em>= <em>r </em>(120-<em>t</em>)
Divide both sides by 120 -<em> t</em>.
= r
Finally, switch <em>r</em> to the left side and you get your answer.

Answer:
Step-by-step explanation:
From x = -2 to x = 0, the average rate of change for both functions is negative
The quadratic function, y = x2, has an x-intercept at the origin
For the quadratic function, y = x2 + 3, the coordinate (2, 7) is a solution to the equation of the function.
those 3 are good
Answer:
Step-by-step explanation:So if he or she answered 12 right and got 80% then if you count to 100% at should be 14 questions I think if i am wrong sorry

Answer:
10
Step-by-step explanation:
How many times greater is the value of 4 in 547 than the value of the 4 and 84?
547: 500 + 40 + 7
5 is in the hundreds place
4 is in the tens place
7 is in the ones place
84: 80 + 4
8 is in the tens place
4 is in the ones place
The value of 4 in 547 is 10 times greater than the value of 4 in 84.
Since the 4 in 547 is in the tens place, while the 4 in 84 is in the ones place.
Also, 4 * 10 = 40
Hope this helps!
