Answer:
F=2/9
Step-by-step explanation:
mult. both sides by -2/3
this will get rid of -2/3 on the left side
whatever is on the right side is the answer
(pls choose this as the brainiest)
Answer:
Domain: All real numbers or (-∞, ∞)
Range: [-9, ∞)
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
Range is the set of y-values that can be outputted by the domain.
We can see that you can plug in any x-value into the graph. Therefore, any number would work (All real numbers).
We can also see that are absolute minimum y-value is -9. Therefore, our range is from -9 (included) to infinity.
Answer:
7 x - 8 y = 5
x - 8 y = -13
6 x = 18 subtract equations
x = 3
7 (3) - 8 y = 5
8 y = 16 solve for y
y = 2
Solution : (3, 2)
Check:
3 - 8 * 2 = -13 agrees with second equation
