Answer:
D. 80 mph
Step-by-step explanation:
d- distance
- d/50= 0.6d/40+0.4d/x
- 1/50= 0.3/20+0.4/x
- 0.4/x= 0.02- 0.015
- x= 0.4/0.005
- x= 80 mph
Answer:
The value of p is not measure through brain but through the fire
Factor to find x intercepts
x intercepts occur where f(x)=0
so
0=f(x)=x^2-5x+4
what2 numbers multiply to get 4 and add to get -5?
-4 and -1
0=(x-4)(x-1)
set to zero
x-4=0
x=4
x-1=0
x=1
x intercepts at 1 and 4
so therefor it is the 3rd option
The answer for this question is -3
