Answer:
Vertex of the parabola is (2,3)
Step-by-step explanation:
The parabola is a negative, it opens down and the maximum place it can reach is 3 (y).
Answer:
d.
Step-by-step explanation:
you would put 4 in the x places and 2 in the yplaces and then you would distribute 4^2 +3(2)/4(2)
16+6/2=22/8=2 3/4
Answer:
Think of y = mx + b,
With y = x + 3, m = 1 so the slope is one, and b = 3 which is the y-intercept, so plot the point (0,3) on the y-axis.
To find the next point to plot go up 1 and over to the right 1 because slope is rise over run.
With y = x, the slope is still 1, but there is no y-intercept, so you plot the point (0,0), and to find the next point on that line, go up 1 and over the right 1 because m=1
Answer:
30 and 40
Step-by-step explanation:
30 and 40
Answer:
All except from point E's y-coordinate (which is -1.5 (found it through the equation y=-1.5 and trying to see if these coordinates are solutions to the above equation) All the others are integers, which you can find through aligning the point on the axis of the chosen (y or x) coordinate.
Step-by-step explanation:
Point C has -2 x-coordinate since it is on the x=-2 line
Similarly, point D has -2 y coordinate,
point E has 2 x-coordinate and -1,5 y-coordinate
and point F , since it's the two axis' common point has coordinates of (0,0).
