Answer:
Yes it is.
Step-by-step explanation:
All whole numbers are integers.
The least time is 9.675 seconds
3.5d+2=7-1.5d
Subtract 2 from both sides
3.5d=5-1.5d
Add 1.5d to the other side
5d=1.5d
d=3.33
Answer: 6.67
Step-by-step explanation:
Using the similarity theory, we get the equation
5/30 = BM/40
BM = 5*40/30 = 20/3 = 6.67
Answer number 2
Answer:
y = 3x - 2
Step-by-step explanation:
The number beside the x is the slope. The number at the end of the equation is the y-intercept.
All the answers are in this form:
y = mx + b
m is the slope.
b is the y-intercept.
With a 3 filled in for slope and -2 filled in for the y-intercept, you get:
y = 3x + -2
is the same as,
y = 3x - 2
