Answer:
4 (20) + 6(6) = 120
4(20) + 4 (6) = 100
Step-by-step explanation:
Hi, to answer this question we have to write a system of equations with the information given:
Build time (hours) = 4c + 6a = 120
Test time (hours) = 4c + 4 a = 100
Where c represents the number of child bikes and a represents adult bikes.
So, for 20 child bikes and 6 adult bikes:
4 (20) + 6(6) = 120
4(20) + 4 (6) = 100
Feel free to ask for more if needed or if you did not understand something.
Answer:

Explanation:
The slope-intercept form of a line is:
y
=
m
x
+
b
where:
m
is the slope of the line
b
is the y-intercept
We are given that
m
=
4
and the line passes through
(
7
,
2
)
.
∴
2
=
