Y would be 42. if you multiple 1.5 by 3 it will be 9. so if divide 21 by 1.5 it equals 14 so multiple 14 by 3 it gives you 42

If y varies directly with x then we have the following function:
y=x + (21 - 1.5) or simply y = x + 19.5.
So, when x=9:
y = 9 + 19.5 = 28.5

find the area of a circle that has a diameter of 11inches approximate as 13.4 round your answer to the hundreth
Vinil7 [7]

To find the area of a circle you do pi (3.14) multiplied by the radius squared.

The radius is half of the diameter: 11 / 2 = 5.5in

The radius squared is 5.5^2 = 30.25

Then take the squared radius and multiply that by pi 30.25 * 3.14 = 94.985

So the area of the circle is about 94. 99 in.

3x=-2y+4 (add 2y)

3x+2y=4 (subtract 3x)

2y=-3x+4 (divide by 2)

y= -2/3x+2
