Answer:

x > -6

Step-by-step explanation:

Solve the following inequality:

x + 7 < 4x + 25

-Take 4x and subtract it from x :

x - 4x  + 7 < 4x - 4x + 25

-3x + 7 < 25

-Subtract 7 on both sides:

-3x + 7 - 7< 25 - 7

-3x < 18

-When you are dividing an integer by a negative integer, then the inequality sign changes. So, Take -3x and divide it on both sides:

\frac{-3x}{-3} < \frac{18}{-3}

x > -6

Therefore, the answer is x > -6.

Can you explain how to do this math problem?

Since the problem is 2x^2-5xy-y^3 we first have to plug in what the x and y stands for, once you do that your problem should look like this:

2(-3)^2- 5(-3)(-2)- (-2)^3

Now take the parentheses away and when you do that your signs change.

2x3^2-5x(-3)x(-2)-(-2)^3    

do it again with -5x(-3)x(-2)

2x3^2-30-(-2)^3

now do this with (-2)^3

2x3^2-30-(-8)

Now evaluate the power

3^2 becomes 9

2x9-30-(-8)

then change -(-8) to a positive since two negatives make a positive

2x9-30+8

Now multiply the numbers 2x9

18-30+8

Then do 18-30 which equals -12 then add 8

Now you are left with your answer:

<u>-4</u>


Hope this helps! :3
