Part A: The shading is in between the lines. The line for y<4x-2 is dotted, while the line for y<span>≥(-5/2)x-2 is solid</span>. The solution area is below the line y=4x-2 and above the line y=(-5/2)x-2.

Part B: (-2,-2) is not in the solution area. We can plug (-2,-2) into the inequalities: -2<4(-2)-2, and -2<(-5/2)(-2)-2. However neither of these are true so it is not a solution.

If 5 ibs apples cost $2.99, how much would 3 ibs cost?
AnnZ [28]

We know that 5 lbs of apples cost $2.99

To know how much do 3 lbs of apple cost, you can use cross multiplication

If 5 lbs cost $2.99

Then 3 lbs cost $x

The proportion between the price and the number of apples is the same, you have to calculate it as:

\begin{gathered} \frac{2.99}{5}=\frac{x}{3} \\ (\frac{2.99}{5})\cdot3=x \\ x=1.794 \end{gathered}

3 lbs of apples cost $1.79

Solve for x:<br> 18x + 3x + 4 - 5 = 5(4x – 9
Luden [163]
Answer:
X= - 44
18x+3x+4-5=5(4x9
Collect like terms
21x+4-5=5(4x-9
More variable to the left hand side and change its sign
21x-20x-1=-45
Correct like terms
X=-45+1
Which is x=-44
