The equation of a line with slope m passing through a point P(a, b) is given by
(y-b)=m(x-a).
We can consider any of the points (-1, 7), or (2, 10). Let's choose (2, 10):
y-10=1(x-2)
y-10=x-2
y-x=-2+10
y-x=8

Answer: x = 23 and y = 13
Explanation:
let x and y be the two number.
Where:
(x + y)/2 = 18 => x + y = 18 x 2 = 36
and:
x - y = 10
Thus we get:
x + y = 36 (1)
x - y = 10 (2)
Add (1) and (2):
x + y + x - y = 36 + 10
2x = 46
x = 23
If x = 23
then x - y = 10
23 - y = 10
-y = -13
y = 13
Answer:
Step-by-step explanation:
Given
(A)
We know that Sin(A + B) = SinA cosB + cosAsinB
Substituting in the above formula we get:
(B) Cos(A + B) = CosAcosB - SinASinB
(C) Tan(A + B) =
From the above obtained values this can be calculated and the value is .
