a. -x, y b. x, y c. x, -y
Step-by-step explanation:
hope this helps:)
You factor the numerator and denominator and cancel the common factors. So maybe that should help you
Concave up is U-shaped.
There will be a inflection/critical point f'(x) =0 then a negative slope f'(x) = neg then another inflection/critical point f'(x) =0 at the bottom of the U-shape then a positive slope to last inflection/critical point. The interval for the Concave Up shape is the first and last inflection points.
Answer:
9:15
Step-by-step explanation:
The solution to the system of linear equations is where the two lines intersect.
Look for the point where the two lines intersect. The x-value is 2 1/2, and the y-value is -4.
The answer is C.
