Answer:
r = -39
Step-by-step explanation:
So we are trying to solve the equation for r.
-6(2r + 8) = -10(r - 3)
Divide both sides by -2. (This will make distributing much easier.)
3(2r + 8) = 5(r - 3)
Distribute the 3 on the left side and the 5 on the right side,
6r + 24 = 5r - 15
Subtract 24 from both sides.
6r = 5r - 39
Subtract 5r from both sides.
r = -39
So now we have solve the equation.

Answer:
The discriminant of function is 0. There one distinct real number zero of 
(repeated roots).
Step-by-step explanation:
We are given the following function in the question:
We have to calculate the discriminant of the function.
Comparing to
We get,
Discriminant is given by:
Putting values, we get,
Thus, the discriminant of function is 0.
Since, the discriminant is zero, the function have repeated real roots. Thus, one distinct real number zero of .
- Mr. Anderson drove 168 miles in 3.5 hours. Distance here is 168 miles.
- He drove for 2.25 at a rate of 5miles/hour. The speed here is 5miles/hour.
Since we are looking for distance, we have to convert the 2nd part (which is the speed) to dostance.
Distance = speed x time
Distance = 5 x 2.25 = 11.25
In the first part, he drove for 3.5 hours. And in the 2nd part, he drove for 2.25 hours which sum up together to be 5.75 hours.
Since we have the distances for both parts now, we just sum it up
which it 168 + 11.25 = 179.25 miles
I hope this is good
