Use the form y=mx+b where m is the slope and b is the y-intercept: y=4/5x-6
X - 2 = - 2x + 7
3x = 9
x = 3
f(x) = g(x) when x = 3.
The proportion that models the problem would be x/850 = 11/17. :)
Barry = 92
heidi = h
92 = h + 18
92 - 18 = h + 18 - 18
74 = h
heidi has 74 marbles
<span>The trapezoid have vertices at (2,0), (2,2), (4,0), and (4,4)
and the rotation </span><span>about the x-axis.
the points (2,0), (4,0) are located on the x-axis
calculate the function y = m x + c using the other </span>vertices <span>(2,2), (4,4)
by substituting in the function y
m = 1 , and c =0
∴ y = x
</span>The volume can be calculated using
