i am working on this atm.
to solve you find the horizontal (x) intercepts.
so example graph A int is +3
then you find the equation where instead of f(x) etc, 0= the equation with the X value plugged in.
IE: 0=x^3-3x^2+x-3
would fit because when you simplify 0=0
0=3^3- 3(3^2)+3-3
0=27-27+3-3
0=0+0
0=0
it matches. so A would be the equation with f(x)
and continue in the same way
63 miles in 270 minutes will mean that nolan rides his bike at a distance of 63/270 miles in one minute.
there are 60 minutes in an hour. So to find out the distance he covers in 1 hour, 63/270 × 60 will give you 14 miles.
Since the question is asking for the average speed, nolan rides his bike at 14 miles per hour i think.
Answer:
a) 20 years
Step-by-step explanation:
Hina: x
Nora: x + 4
x + x + 4 ≤ 45
2x + 4 ≤ 45
2x ≤ 41
x ≤ 20.5
20 years old and 15 years old would be ≤ 20.5 but the question asked for maximum possible age so 20 years old it is.
Answer:
Colin is 8 and Bill is 29
Step-by-step explanation:
29-8=21
8+13=21
29+13=42
21 is half of 42
