Answer:
Xmin:
-10
Xmax:
10
Ymin:
-10
Ymax
10
Step-by-step explanation:
Dy/dx=-2x+15
d2y/dx2=-2
Since the acceleration is a constant negative it has an absolute maximum value for y(x), thus it opens downward, as x decreases without bound as x approaches ±∞
Answer:
yes
Step-by-step explanation:
y < 2x +4
6 < 2·5 +4
6 < 14
Answer:
It is not accurate because only information from teenagers was used to make the claim.
Step-by-step explanation:
This is the correct answer because they only used the data that pertained to their teen readers. The magazine does not only have teen readers, but has many ages. The statement regarding internet use generalizes it to all readers, not just teens, therefore making its claim inaccurate because the scope of inference is not appropriate for the claim that was made.
Answer:
A. (1, -2)
B. the lines intersect at the solution point: (1, -2).
Step-by-step explanation:
A. The equations can be solve by substitution by using the y-expression provided by one of them to substitute for y in the other.
This gives ...
3x -5 = 6x -8
Adding 8-3x to both sides, we get ...
3 = 3x
Dividing both sides by 3 gives ...
1 = x
Substituting this value into the first equation, we can find y:
y = 3(1) -5 = -2
The solution is (x, y) = (1, -2).
__
B. The lines intersect at the solution point, the point that satisfies both equations simultaneously. That point is (1, -2).
