1) Solve: 8x ¨C (6x + 4) = 8

x = -2

2) -7x > 1/15

the solution set is: {x | x > -105}

3) Solve 5> -4x + 4 or 10 ¡Ü -4x +3

the solution to the inequality is:

[-¡Þ, -7/4] U [-1/4,¡Þ]

4) Use < or > to make the statement true: -9 < 3

5) Graph the inequality on a plane: 5x + 6y ¡Ü 30 not even sure where to start with this one

6)Solve using the multiplication principle.

-5/6x = -7/8

The solution is? 21/20

7) Soybean meal is 14% protein; cornmeal is 7% protein. How many pounds of each should be mixed together in order to get 280-lb mixture that is 11% protein?

How many pounds of the cornmeal should be in the mixture?

How many pounds of the soybean meal should be in the mixture?

how do i solve this?

8) Solve the following system of equations.

X + 9y = 2 (1)

X = 6 ¨C 9y (2)

What is the solution of the system?

9) Solve: 5/2x + 1/4x = 7/4 + x

The solution is x = ?

10) Find the slope, if it exists, of the line containing the pair of points
