Answer:
Step-by-step explanation:
The equation of a straight line can be represented in the slope intercept form as
y = mx + c
Where
m = slope = (change in the value of y in the y axis) / (change in the value of x in the x axis)
The equation of the given line is
x + 2y = 4
2y = - x + 4
y = -x/2 + 4/2
y = - x/2 + 2
Comparing with the slope intercept form, slope = - 1/2
If two lines are perpendicular, it means that the slope of one line is the negative reciprocal of the slope of the given line.
Therefore, the slope of the line passing through (- 2, 1) is 2
To determine the intercept, we would substitute m = 2, x = - 2 and y = 1 into y = mx + c. It becomes
1 = 2 × - 2 + c = - 4 + c
c = 1 + 4 = 5
The equation becomes
y = 2x + 5
Answer:
5
Step-by-step explanation:
=2+(3)(16)-(2)(21)-3
=2+48-(2)(21)-3
=50-(2)(21)-3
=50-42-3
=8-3
=5
Hope this helped! :)
N, N+2, and N + 4 are the ages
(N + 4) - (2N) = (N + 2) -24
4 - N = N - 22
2N = 26
N = 13
The brothers are 13, 15, and 17 years old.
