Question Write an equation of the line passing through the point A(0, 3) that is perpendicular to the line y = −1/2x−6

Mathematics

White raven [17]2 years ago

Answer:

The equation would be y=2x+3 I am pretty sure

Step-by-step explanation:

This is because you take the slope which is 2 from the line y=-1/2x-6. To find the slope perpendicular to the line, you need to find the exact opposite of the slope: -1/2, and in this case, it would be 2.

(Ex: if it was -3/4, you would need to use a slope of 4/3 since it is the opposite)

Then you take that slope (2) and the point (0, 3) and put it into "y-y1=m(x-x1)"

y-y1=m(x-x1)

y-3=2(x-0)

-distribute the 2-

y-3=2x-0

-add 3 on both sides-

so equation would be y=2x+3

Not sure if this is all correct, but I hope it helps! :)

The ratio of rock music to total CDs that Ella owns is 25/40. Paolo has 50 rock music CDs. The ratio of rock music to total CDs
eimsori [14]
They own a total of 120 CDs. Ella's CD is 40 while Paolo's CD is 80.

Given:
Ella's ratio of rock music to total CDs = 25/40
Paolo's ratio of rock music to total CDs = 50/x

25/40 = 50/x
25x = 40*50
25x = 2000
25x/25 = 2000/25
x = 80 

Total CDs
Ella           =   40
Paolo        =   80
Total CDs = 120
