Answer:
Step-by-step explanation:
Assuming she runs at the same pace, this will be a simple problem to solve. First we have to find that rate. She ran 5 miles in 38 minutes. This means she ran about 0.131 miles per minute. Then we just have to multiple that rate by 57 minutes to find out that at the same pace she would have run about 7.5 miles.
Hope I Helped :)
This should help you here are the steps of your problem :)
2*(1/2)*r+2*r+1 = 9*(1/10) // - 9*(1/10)
2*(1/2)*r+2*r-(9*(1/10))+1 = 0
2*(1/2)*r+2*r-9/10+1 = 0
3*r+1/10 = 0 // - 1/10
3*r = -1/10 // : 3
r = -1/10/3
r = -1/30
r = -1/30
So your answer would be 1/30
Reflection over the x-axis is (x,y) goes to (x,-y)
So g(x) goes to -3x
Y=mx+b
Mx is the rate of change
B is your starting point
Started with 1000, A
-200 is the rate of change, D

PLEASE MARK AS BRAINLIEST
Step-by-step explanation:
5 x 4.5 = 22.5 (km)
150 – 22.5 = 127.5 (km)
35 – 5 = 30 (km/h)
127.5/30 = 4.25 (h)
4.25 x 35 = 148.75 (km)
Alternatively,
Let x be the distance that he cycles.
x/35 + (150 – x)/5 = 4.5
x + 1050 – 7x = 157.5
6x = 892.5
x = 148.75
Ans : 148.75km.
