Using linear functions, it is found that:
- Jose's equation is: .
- Gavin's equation is: .
- They will be on the same page on the 9th day.
<h3>Linear function:</h3>
A <em>linear function</em> is modeled by:
In which:
- m is the slope, which is the rate of change.
- b is the y-intercept, which is the value of y when x = 0.
Jose:
- Initially, he was on page 10, hence .
- He reads 17 pages per day, hence .
- Hence, Jose's equation is: .
Gavin:
- Initially, he was on page 37, hence .
- He reads 14 pages per day, hence .
- Hence, Gavin's equation is: .
The day they will both be on the same page is x for which:
Hence:
They will be on the same page on the 9th day.

Answer:
53 1/3 km/h
Step-by-step explanation:
average speed = (total distance)/(total time)
average speed = distance/time
time * average speed = distance
time = distance/(average speed)
250 km at 75 km/h
distance = 250 km
time = (250 km)/(75 km/h) = 3.33333... hours
350 km at 70 km/h
distance = 350 km
time = (350 km)/(70 km/h) = 5 hours
200 km at 30 km/h
distance = 200 km
time = (200 km)/(30 km/h) = 6.6666... hour
total distance = 250 km + 350 km + 200 km = 800 km
total time = 3.33333... hours + 5 hours + 6.66666... hours = 15 hours
average speed = (total distance)/(total time)
average speed = (800 km)/(15 hours)
average speed = 53 1/3 km/h
Answer:
x>−15
Step-by-step explanation:
−x+5<20
Step 1: Subtract 5 from both sides.
−x+5−5<20−5
−x<15
Step 2: Divide both sides by -1.
−x
−1
<
15
−1
x>−15
Answer:
x>−15
Step-by-step explanation:
Reduce = Deduct = Subtract
7y + 2y^2 - 7 - (3 - 4y)
distribute the negative sign outside 3-4y.
7y+2y^2-7 - 3 + 4y
collect like terms, meaning try to make similar components of the equation together at one place.
7y & 4y are like terms in this case.
7y + 4y + 2y^2 - 7 - 3
11y + 2y^2 - 10
rewrite 2y^2 infront of the equation because it has the highest degree which is 2.
2y^2 + 11y - 10
