Answer:
A(2/3, 6)
B(15, 33)
Slope=81/43
Step-by-step explanation:
If for the first point A Y=6, you can just plug it into the spot for the Y in the equation.
So that get's you the equation 6-2x=3
Solving the equation you get:
2x=3
x=2/3
So that means that for point A your coordinate pair is (2/3, 6)
You do the same for B.
B has point X=15, so plug it in:
y-2(15)=3
y-30=3
y=33
So your coordinate pair for B is (15, 33)
Then to find the slope you follow the equation y2-y1/x2-x1
Plugging in the numbers you get:
33-6/15-2/3
27/43/3
81/43
So your slope=81/43
It saves room when writing or calculating an equation.<span />
Hello from MrBillDoesMath!
Answer:
x = 10
Discussion:
A plane triangle contains 180 degrees. Adding the angles in the triangle shown in #8 gives
(4x + 7) + (3x + 13) + 90 = 180
Note the "right angle" shown in the triangle has been replaced by its 90 degree equivalent in the above equation.
Combining like terms gives
( 4x + 3x) + (7 + 13) + 90 = 180
7x + 20 + 90 = 180 => (subtract 90 from each side)
7x + 20 + 90 - 90 = 180 - 90 = 90 =>
7x +20 = 90 => (subtract 20 from each side)
7x + 20 -20 = 90 -20 =>
7x = 70 =>
x 70/7 =10.
Thank you,
MrB
