Answer:
Step-by-step explanation:
8x+5y = 20
y = (-8/5)x + 4
slope of the line is -8/5.
slope of any perpendicular to the line is ⅝.
line of slope ⅝ that passes through P(4,5):
y-5 = ⅝(x-4)
y = ⅝x + 2.5
find intersection of lines
⅝x + 2.5 = (-8/5)x + 4
25x + 100 = -64x + 160
89x = 60
x = 60/89, y = 260/89
distance between (60/89, 260/89) and (4,5) = 3.92
Answer:
5/6 = 20/24
5/8 = 15/24
Step-by-step explanation:
These are the answers because:
1) First, the least common denominator is 24 because 8 x 3 is 24 and 6 x 4 is 24
2) Next, multiply the numerators with the same number you multiplied with the denominator
5 x 3 = 15
5 x 4 = 20
3) Therefore, the answers are:
5/6 = 20/24
5/8 = 15/24
Hope this helps!
Y=1/2x-4
Perpendicular means it is opposite and the reciprocal. 1/2(4) = 2-4 equals -2.
