Answer:
x=4.875
y=-0.25
Step-by-step explanation:
4x – 2y = 10
2x-y=10
y=2x-10
4x + 6y = 18
2x+3(2x-10)=9
8x=39
x=4.875
y=2(4.875)-10
y=-0.25
Yes it is the right answer .-.
Answer:
I'll give you the answers for 1 - 5: 1). 24, 2).19, 3)10, 4)13, 5)-17
Step-by-step explanation:
You simply substitute the corresponding values for the corresponding function:
f(6) if f(x) = 4x so, f(6) = 4(6) = 24
Another example:
f(5) if f(x) = 3x - 2 so, f(5) = 3(5) - 2 = 15 - 2 = 13
