How do you graph:<br><br> y≤−4x+40 <br><br> and <br><br> y≤10
Arturiano [62]

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.

What is the x <br> 0.02+0.7=0.8-0.3x
pav-90 [236]
X = 4/15 or 0.26

First add the numbers on the left side of the equation.

0.72 = 0.8 - 0.3x

Then move the variable to the left as well.

0.3x + 0.72 = 0.8

Move the constant to the right by subtracting.

0.3x = 0.8 - 0.72

Subtract the numbers

0.3x = 0.08

Divide both sides by 0.3.

And that should yield your answer.

Hope this helps. ^^
