Answer:
Step-by-step explanation:
f(x) = (x + 3)(x - 2) has two zeros: One stems from (x + 3) = 0 and is (-3, 0); the other stems from (x - 2) = 0 and is (2, 0).
The axis of symmetry is a vertical line located halfway between -3 and 2:
x = -1/2.
The graph opens up because the given (x + 3)(x - 2) has a positive leading coefficient (+1).
With this information we can eliminate the last two possible answers. Note that the x-intercepts of the first graph are -3 and 2, Thus, the first graph is the correct one.
Answer:

2. 13x/10
Step-by-step explanation:
explanation: find the common denominator and then go from there. i suck at in depth explanations but as long as you get the gist of it youre good
.10 I hope that that helps you :)
Answer:
x=1.167 y=8
Step-by-step explanation:
The y-intercept is where the graph crosses the y-axis. To find the y-intercept, we set x2=0 and then solve for y.
7x - 6y = 48
7(0) - 6y = 48
y2 = -8 x2 = 0
(x1,y1) and (x2,y2)
(6.857,0) and (0,-8)
6.857,0) and (0,-8)
The slope of the line (m) is the steepness of the line. It is the change in the y coordinate divided by the corresponding change in the x coordinate. Simply plug in the coordinates from above and solve for m to get the slope for 7x - 6y = 48
m = (y2 - y1)/(x2 - x1)
m = (-8 - 0)/(0 - 6.857)
m = 1.167
Answer:
215
Step-by-step explanation:
you add all three together and then divide by three to get the average.
