Answer:
y = 30
Step-by-step explanation:
Use the direct variation equation, y = kx
Plug in 20 as y and 8 as x, then solve for k:
y = kx
20 = k(8)
2.5 = k
So, the equation is y = 2.5x
Plug in 12 as x, and solve for y:
y = 2.5x
y = 2.5(12)
y = 30
So, when x = 12, y = 30
Answer:
-8
Step-by-step explanation:
Hope this helps, have a great day:)
Because tan theta > 0 and cos theta is negative this angle is in the third quadrant.
angle whose cos is 2/5 is 66.42 degrees
The required angle is 180 + 66.42 = 246.42 degrees answer.
Y = 3/2x -6
1) canceled out the 3x by using the subtraction property of equality.
2) dividing all terms by -2 on both sides.
3) resulting in getting Y = 3/2x - 6
