Z=2.65
x=10.39
thats your two answers
[75 x 15 + 25 x 16] / (75+25) = 1525/100
=$15.25
Y=3\4+2
Slope=rise/run. 3\4
Y-intercept = 2
Answer:
Look at the explanation.
I'll be online so let me know if you still need help.
Step-by-step explanation.
A system of equations is basically two or more equations that rely on each other. If a solution for a variable is 2, it has to work for the other equation.
The substitution is basically plugging in the y value to y = 8x + 10
If y = 2
and also y = 8x + 10
What do you think the substitution is?
