The answer are B, D and F.
If you solve for x for B, D and F, you'll get (1/2,5)
Answer:
See attached picture.
Step-by-step explanation:
To graph linear inequalities, use the y=mx + b form to graph using the slope and y-intercept.
y ≤ -4x + 40 has slope -4 and y-intercept (0,40).
Start at (0,40) and mark it. Then move down 4 units and to the right 1. Mark this point at (1,36). Connect the points with a solid line since the inequality has equal to. Substitute a point like (0,0) to test where the solution set is.
0 ≤ -4(0) + 40
0 ≤ 0 + 40
0 ≤ 40
This is true so shade to the left of the line.
To graph y ≤ 10 mark a point on the y-axis at (0,10). Draw a horizontal solid line through the point. Then shade below the line.
Answer: instead of X put 5 and instead of y put 2
5+6(2)
5+12= 17
The easiest way to solve this is to convert all of the values to a decimal value, and then order the numbers as you normally would.
1/5=0.2
-4.06
10/5=2
-4.30
Now that we know the decimal values, we can simply place them from least to greatest. -4.30, -4.06, 1/5, 10/5 is the correct order.
