Given ΔABC with A(-6, -1), B(3, 7), and C(4, -6)
Since it is an altitude and pass thru B, t
hen it is perpendicular to AC.
so slope(AC) = (-1 +6)/(-6 - 4) = -5/10 = -1/2
perpendicular lines, slope is opposite and reciprocal so slope = 2
passes through B(3, 7)
y - 7 = 2(x - 3)
y - 7 = 2x - 6
y = 2x + 1
equation in slope intercept form:
y = 2x + 1
Answer:
Formula to the area of a parallelogram is A = base x height
A = 14.3 x 11.4
A = 163.02in^2
(you got it right!)
The answer is 21.5 or in a fraction its 43/2
Answer:C
Step-by-step explanation:
Answer:
1/10
Step-by-step explanation:
Percent spent on cable TV = 10%
Percent means "per hundred".
So, we can write 10% as,
10/100
= 1/10
So the family spent 1/10 of their total budget on cable TV.
