Answer:
y =1/2x+6
y = -2x+2
Step-by-step explanation:
Perpendicular line have slopes that multiply to -1
The slopes are negative reciprocals
-4*4 = 16 not perpendicular
1/2 * -2 = -1 perpendicular
1/5 *5 = 1 not perpendicular
2/3 * 2/3 = 4/9 not perpendicular
Answer:
Getting through ratio method
100-20=80 percent have to pay
18:80
<em>x</em>:100
cross multiply
80 x <em>x=1</em>8 x 100
80x=1800
x=1800/80
x=22.5
So the original price was $22.50
Step-by-step explanation:
So, to find the constant we do this:
1.2n = 93,000,000
so n = 77500000So, with this constant, we multiply n with 0.86
0.86n = <span>66650000
So Venus is about </span><span>66,650,000 million miles away from the sun</span>
