Q:
# 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, ∞)

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, ∞)
