Answer:

Step-by-step explanation:
There are 2 factors of 5, so you have 5^2
There are 3 factors of x, so you have x^3
There is a single y, so you have y
Answer: 
Use distributive property
3(x + 2) = 2(2x + 7)
(3)(x) + (3)(2) = (2)(2x) + (2)(7)
3x + 6 = 4x + 14 |subtract 6 from both sides
3x = 4x + 8 |subtract 4x from both sides
-x = 8 |change the signs
<h3>x = -8</h3>
Answer:
The graph is as attached.
Step-by-step explanation:
Simply draw a line of x = 2 on your graph paper.
That line should be a complete line not dotted line.
Since x is greater than 2, shade the left side of the line because we are interested in the right side (where x is greater and equal to 2)
