Answer:

Step-by-step explanation:

Dividing both sides by -7.


There is only one solution that satisfies the equation.
Answer:
What the equation is telling us is that after opening for 1 hour 15 minutes, there were 28 visitors
Step-by-step explanation:
The function we are given is ;
V(1.25) = 28
what this mean is that the number of visitors in the museum after 1.25 hours of opening is 28
1.25 hours is same as 1 hour (0.25 * 60) minutes
What is in the bracket is trying to convert the 0.25 hours to minutes
Since 1 hour is 60 minutes, 0.25 will be (0.25 * 70)
Which is 1 hour 15 minutes
So after opening for 1 hour 15 minutes, the museum had 28 visitors
Total age of pupils
= 12.7 x 10
= 127 years
127 - 11 - 10 - 12 - 11 - 14 - 13 - 14 - 16 = 26 ( total age of the other 2 pupils added together )
however, since the ninth pupil is two years younger,
26-2=24
24/2=12 ( age of ninth pupil )
12+2=14 ( age of tenth pupil )
thus, (a) 12 years old,
(b) 14 years old.
Answer:
A
Step-by-step explanation:
notice that the graph has a vertical asymptote.
to find a VA, you set the denominator = 0.
since the VA is at x = 5, choice A is the only one with a denominator that = 0 when 5 is plugged in
Answer: 7y-1
Step-by-step explanation:
Product of number y and 7 is 7y
One less is 7y-1
