Answer:
C. (35, 3.5)
Step-by-step explanation:
its the only pair that is on the line
35 is the x-axis and 3.5 is the y-axis so you go to 35 then up to 3.5 and the pair is on the line
Answer:
Step-by-step explanation:
First off, we are given a parabola by definition:
Since , our parabola has an upward opening.
Should we think about it graphically, it will be no wonder that we should pay our attention to the points of the parabola intersecting the abscissa axis. In other words, we need our vertex to intersect the x axis only once per se.
The vertex:
As a result, our is parametric. suits us because . If , we do not have any roots at all. We have two roots if .
Answer:
if we are solving for x then it would be
x ≤ −

Multiple (5x+y= 28) by 6 giving you 30x +6y =168 and then you would add the two equations together, giving you 38x = 152, divide both sides by 38, giving you 4. after this, you would sub x=4 into one of the equations (i’m using the 5x+ y =28) which would give me 20 + y = 28, subtract 20 by both sides, giving you y= 8. so your answer is (4,8)
