Here is the answer to the problem.
Slope = (-5-1)/(7+1) = -6/8 = -3/4
Perpendicular slope = 4/3
Midpoint = ((-1+7)/2 , (1+(-5))/2) = (3, 3)
equation:
y = mx + c
y = 4/3 x + c
at point (3, 3)
3 = 4/3(3) + c
c = 3 - 4 = -1
y = 4/3 x - 1 or 3y = 4x - 3
Answer:
17
Step-by-step explanation:
These two angles add up to 180, so we can set up an equation. 5x-23+7x-1=180. Now we combine like variables, getting 12x-23-1=180. We add 23 to both sides, and get 12x-1=203. Then we add 1 to both sides, getting 12x=204. Finally we divide by 12 on both sides, with our result as x=17.
Answer:
y=-4/23
im not sure i didn't check (might be wrong)
Step-by-step explanation:
4x - 5y = -28
-3x - 2y = 10
then make x the same
So
12x-15y=-84
-12x-8y=80
then its left with
-23y=-4
y=-4/23
find x by entering y into -3x - 2y = 10 and solving
Example 2: x=10
Example 3: x=-1
Example 4: x=35
Example 5: a-b+c=9
Example 6: x=1, x=1/2
Further explanation:
