Answer:
D
Step-by-step explanation:
We observe that the values of m are 10 less than the corresponding values of n, that is
n = 10 → m = 10 - 10 = 0
n = 12 → m = 12 - 10 = 2
n = 15 → m = 15 - 10 = 5
n = 19 → m = 19 - 10 = 9
In general
m = n - 10 → D
Hope this helps:)
(2x+5)(6x-1) I wanted to make sure you could understand it
Hey there! Remember that perpendicular lines are the negative reciprocal to the original slope. With that in mind, the best way to find the slope is by using equation m=y2-y1/x2-x1, so then if we plug this in we get:
-4-3/2-(-1)
As -4 is our y2, -3 is our y1, 2 is our x2, and -1 is our y1.
You should get -7/3, that’s the original slope. Since this is a perpendicular line we MUST FLIP it and CHANGE THE SIGN.
So our FINAL answer would be: 3/7
Hope that helps!!!
Answer:
Step-by-step explanation:
It is hard to guess the coordinates of any points, because the graph doesn't go through any intersections of the grid.
Fortunately, I can tell that the axis of symmetry is x=2.
Put the equation into vertex form by completing the square.
axis of symmetry = b/2
b/2 = 2
b = 4
Answer:
y+2 = (-1/2)(x-3)
Step-by-step explanation:
Note that as we move from (-17,8) to (3,-2), x increases by 20 and y decreases by 10. Thus, the slope of this line is m = -10/20, or m = -1/2.
The standard equation in point-slope form is y - k = m(x - h), where (h, k) is a point on the line and m is the slope of the line. Then, taking data from the point (3, -2), we have
y+2 = (-1/2)(x-3).
Check: Does the point (-17,8) satisfy this equation? Is 8+2 = (-1/2)(-17-3) true?
Is 10 = 10 true? Yes.
