Solve for x: -6(x + 4) + 9 > -5(x + 6)
devlian [24]

Answer:

x < 15

Step-by-step explanation:

Let's first expand the parentheses on both sides. Remember that when expanding parentheses, the result will be the sum of the products of the "outside number" with each of the "inside number".

On the left, the parenthetical expression is: -6(x + 4). Here, the outside term is -6 and the inside terms are x and 4. So:

-6(x + 4) = -6 * x + (-6) * 4 = -6x - 24

On the right, the parenthetical expression is: -5(x + 6). Here, the outside term is -5 and the inside terms are x and 6. So:

-5(x + 6) = -5 * x + (-5) * 6 = -5x - 30

Now put these back in:

-6(x + 4) + 9 > -5(x + 6)

-6x - 24 + 9 > -5x - 30

-6x - 15 > -5x - 30

x < 15

Thus the answer is x < 15.

Hope this helps!

Okay i need help finding y x 6 for y = 2/3 please help
aleksandr82 [10.1K]
First, you need to substitute y for 2/3:

2/3 • 6

Next, change 6 into a fraction and multiply straight across:

2/3 • 6/1
12/3

Finally, simplify it to its simplest form:

4
Your answer should be 4.
Hopefully that helped!

If the Quadratic functions for the equations are graphed, which is the widest?
Amanda [17]

y = ax^2

If the absolute value of a is <1 the graph is wider than when a = 1

If the absolute value of a is >1 the graph is narrow than when a = 1

The only function that fits that description is  

y = 2x^2
