Consider the equations below. y = 200 + 350x y = 3x When x = 7, which equation has the greater value? Drag the equations into the correct boxes so that the inequality statement is true: ______ > _____
Accepted Solution
A:
Let y1=200 + 350x y2=3x
for x=7 y1=200+350*7----------> y1=200+2450------> y1=2650 y2=3*7--------------------------> y2=21
then y1 > y2 (200 + 350x) > (3x)
the answer is (200 + 350x) > (3x)
the solution of this inequality is 350x-3x > -200-----------> 347x > -200 x > -0.5764 the solution is the interval (-0.5764, ∞)
