Answer:
The solution is (2,6)
Step-by-step explanation:
Let
x-----> the number of hours to change a fuel injection unit
y-----> the number of hours to change a transmission
we know that
5x+10y=70 -----> equation A
8x+8y=64 -----> equation B
Solve the system of equations by graphing
Remember that the solution of the system of equations is the intersection point both graphs
The solution is the point (2,6)
see the attached figure
Answer: 9
Step-by-step explanation:
4x²-7x+7 f(2)=4*(2)^2-7(2)+7=16-14+7=9
Answer:
y = 12
Step-by-step explanation:
A line parallel to y = 6 is, like y = 6, horizontal. Such a line passing through (10,12) is y = 12.
Answer:B
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
2/3 want to go

2/3 = 20/30
So 20 people would like to go :O
Hope this helps, have a nice day :))
