I believe it is -20.
Hope that helped you out.
We want a in terms of b and c: <span>3a+4b=c
Isolate 3a on the left side: 3a = c - 4b
Divide all terms by 3:
a = c/3 - 4b/3 (answer)</span>
Your answer would be option 2. Use the slope formula to see if any sides are perpendicular. This is because a right triangle must have 2 perpendicular sides that form a 90° angle for it to be a right triangle, so finding these would prove it.
I hope this helps!
Answer:
Domain (-3,-2,-1,0,1,2)
Range (-2,0,1,2,3)
This is not a function
Step-by-step explanation:
Domain (-3,-2,-1,0,1,2)
Range (-2,0,1,2,3)
one x-value with two y-values, (-1, 2) and (-1, -2)
not a function
Plotting the graph should be easy
left side are x-values
right side are y-values
If you use Y=x+ whatever number you will get your answer
