Answer:
<h2>-6x + 7y = 11</h2>
Step-by-step explanation:
The point-slope form of an equation of a line:
m - slope
The formula of a slope:
We have the points (-3, -1) and (1/2, 2). Substitute:
Convert to the standard form Ax + By = C:
<em>multiply both sides by 7</em>
<em>use the distributive property</em>
<em>subtract 7 from both sides</em>
<em>subtract 6x from both sides</em>
Answer:
Step-by-step explanation:
The centroid is 1/3 the distance from the side to the opposite vertex. Hence ...
... PR = (1/3)(MP + PR)
... 3PR = MP + PR . . . . . . multiply by 3
.. 2PR = MP . . . . . . . . . . . subtract PR
... PR = MP/2 = (14x +8y)/2 . . . . . divide by 2, substitute for MP
... PR = 7x +4y
Of course, MR = MP + PR, so ...
... MR = (14x +8y) + (7x +4y)
... MR = 21x +12y
Answer:
sec(x)-1/sin power 2(x)=<u><em>sec power 2(x)</em></u>
Answer:
Then one possible solution could be n = 31 If 14 + n ≥ 43
Step-by-step explanation:
Substitute: 14 + 31 ≥ 43
Simplify: 45 ≥ 43
n = 31 makes that statement true.

Answer:
A. Count by hand.
B. Divide 20 by 2.
Step-by-step explanation:
The midpoint between two points is found by the mean of their coordinates.
Endpoints at (0,0) and (20,0)
So we have x coordinates of 0 and 20. Their mean is:
So we can find both counting by hand, or dividing 20 by 2.
