Answer:
(-3, -4)
Step-by-step explanation:
we have
----> equation A
----> equation B
equate equation A and equation B




The solutions of the quadratic equation are x=0 and x=-3
Find the values of y
For x=0

For x=-3

therefore
The solutions of the system are the points (0,2) and (-3,-4)
Average rate of change = y2-y1/ x2-x1. so pick the y intercept and 3 second points and plug in to calculate.
Answer:
I think the answer is 1280
Answer:
Distance = rate x time or d = rt...that means time t = d/r...and we have
t = 21 km / .5 km/hr = 42 hr

Answer:
-3y+39x-4
Step-by-step explanation:
3y minus 7y plus y is -3y. 18x plus 21x is 39x. 9 minus 13 is -4
