Answer:

x1

Step-by-step explanation:

We have:

(x+5)(x-1)

And we want to find the value of x such that the expression is positive. So, we can write this as the following inequality:

(x+5)(x-1)>0

Solve for the inequality. First, we can solve for the zeros like a normal quadratic. So, pretend the inequality is with an equal sign:

(x+5)(x-1)=0

Zero Product Property:

x+5=0\text{ or } x-1=0

On the left, subtract 5.

On the right, add 1.

So, our zeros are:

x=-5, 1

Since our inequality is a <em>greater than</em>, our answer is an "or" inequality with our answer being all the values to the <em>left</em> of our lesser zero and all the values to the <em>right </em>of our greater zero.

So, our solution is:

x1

And we're done!

I need more help thank

Answer:

B. 24

Step-by-step explanation:

Since both triangles are similar, therefore,

GM/XD = AG/KX

(x - 2)/6 = (x + 9)/9

Cross multiply

9(x - 2) = 6(x + 9)

9x - 18 = 6x + 54

Collect like terms

9x - 6x = 18 + 54

3x = 72

Divide both sides by 3

x = 72/3

x = 24

8t-9 is less than or equal to 79
sattari [20]

Answer:

t ≤ 11 (or all values 11 or less)

Step-by-step explanation:

8t - 9 ≤ 79

<em>So, I am assuming you are trying to find the value(s) of "t".</em>

Add 9 to both sides.

8t ≤ 88

Divide 8 by both sides.

t ≤ 11

ANSWER

t ≤ 11
