Answer:
x=2
Step-by-step explanation:
x=2 in the equation 3x+5=19-4x
A bicyclist travels at a constant speed of 12 miles per hour for a total of 45 minutes.
We know the formula , Distance = speed * time
Speed is constant and it is 12. So it is linear
The function becomes d = 12t, x is the t is the time and d is the distance
At the starting point, t=0 and distance d=0
End point , t=45 min = 0.75 hours and distance = 12 * 0.75 = 9
So domain (t) is {
}
Range (d) is {
}
C. 452.16
use formula pir^2
12^2 = 144
144 x 3.14 = 452.16
I used pi as 3.14
Answer:
10
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
Substitute by x = 2 and y = - 1
You will get 2*2 + (-1) = 3 not 5
Then it doesn't lie
