2x+3(underlined inequality)<17
1. Subtract 3 from both sides.
2. Divide by 2
3. Your answer should be.....7!

For this measurement, tell whether it could be the length of the sides of a triangle?
4 in, 4 in, 6 in
Yes!
Because the sum of the two sides is greater than the third side.

Graph each pair of equations and estimate the break-even point.
E = 220 + 4.3x
I = 5x
(Calculator Answer)
Break-even point: 333.3

3x + 2y = 1
x + y = 1
(-1, 2)

23>12-x/9
1. Subtract 12 from both sides.
2. 11>-x/9
3. Multiply both sides by 9.
4. Your answer should be.....99>x!

Use algebra to find each break-even point. Round decimal numbers to the nearest tenth.
E = 725 + x
I = 6.5x
131.8
(The break-even point is the point on the graph where the two lines intersect!)
(It can also be solved using algebra)

3/4x + 1/2y = -1
5/8x + 2/5y = 2
(112, -170)

x/(6)-2(underlined inequality)>10
1. Add two to both sides.
2. x/(6)(underlined inequality)>12
3. Your answer should be.....x>72
