Answer:
Total time of the concert = 59.5 min = 59 minute 30 seconds
Explanation:
At a school concert the orchestra plays 8 songs that are 4.25 min and 3 songs that are twice as long as each of the others.
Total length of 8 songs = 4.25*8 = 34 min
Length of 3 songs = 2*4.25 = 8.5 min
Total length of 3 songs = 3* 8.5 = 25.5 min
Total time of the concert = 34 + 25.5 = 59.5 min = 59 minute 30 seconds
Translating something horizontally is just like scooting a glass across a table. It doesn't flip or turn, it just slides. Same would apply for this. You just scoot the image over. Therefore, it would be 'C'
Answer:
A 6f + 12 = 6(f +7)

6f + 12 = 18f
6(f+7)= 42
bc u have to multiply so that means this is the correct option
Answer:
x = 0, -3, 3
Step-by-step explanation:
When f(x) = 0, this means the y-coordinate is 0. Look at the graph to see where f(x) intersects at y = 0.
It intersects at (-3, 0), (0, 0), and (3, 0).

Explanation:
The problem statement tells you the meaning of t. It is minutes after Riko leaves. 0 ≤ t < 52.5 is the answer to the question regarding the interval Riko is behind Yuto. It means Riko is behind Yuto for 52.5 minutes after she leaves their house.
t will not be negative because time moves forward. Here, we're only counting time <em>after Riko leaves the house</em>. A negative value for t would refer to a time before Riko leaves the house, which is irrelevant in this problem.*
_____
* One might argue that Riko is behind Yuto for all values of time <em>after Yuto leaves the house</em>, which would be for -21 < t < 52.5. The concept of "behind Yuto" has no meaning except in that interval.
