The first one, ten times as small and then the answer in parenthesis
Answer:
x = 75 degree
Step-by-step explanation:
Angle between C and B must equal 90 degree.
90- 15 equal 75 degree.
Knowing this angel C and E is equal to angel F and D
5x - 3y = 10
x + y = 7......multiply by -5
------------------
5x - 3y = 10
-5x - 5y = -35 (result of multiplying by -5)
------------------add
-8y = -25
y = 25/8
x + y = 7
x + 25/8 = 7
x = 7 - 25/8
x = 56/8 - 25/8
x = 31/8
solution is (31/8 , 25/8)
Answer:
Step-by-step explanation:Given:
Two points (-10,-7),(-5,-9).
To Find:
Equation of line through these points?
Step-by-step explanation:
We know equation of line through is given by
Put the value in equation we get
Hence, equation of line is 5y+2x=-55.
The answer is -1/3
The slope m is:
m = (y2 - y1) / (x2 - x1)
(x1, y1) = (-2, 2)
(x2, y2) = (4, 0)
m = (0 - 2) / (4 - (-2)) = -2 / 6 = -1/3
