- Zero Product Property: if a × b = 0, then either a or b = 0 or both a and b = 0.
(Make sure to set f(x) to zero)
So for this equation, I will be factoring by grouping. Firstly, what two terms have a product of -5x^2 and a sum of 4x? That would be 5x and -x. Replace 4x with 5x - x: 
Next, factor 5x^2 + 5x and -x - 1 separately. Make sure that they have the same quantity on the inside: 
Now you can rewrite the equation as: 
Now apply zero product property to the factors to solve for x:
<u>The x-intercepts are (1/5 ,0) and (-1,0).</u>

Step-by-step explanation:
Answer: D
Step-by-step explanation: We first need to solve the inequality.
First subtract 10 from both sides to get -x < -8.
Now divide both sides by -1, but watch out.
If you multiply or divide both sides of an inequality by
a negative number, you must switch the direction of the inequality sign.
So we have x > 8.
Start with an open dot at 8 and draw and arrow to the right.
We use an option dot since x is greater than but not equal to 8.
So option D is your answer.
Answer:
24 cups
Step-by-step explanation:
To find the amount of peaches in a fruit salad, you would multiply the cups of salad by 2/5 because 2 cups of peaches are dedicated to the fruit salad for every 3 cups of cherries, having the peaches make up 2 out of every 5 cups or 2/5. So the equation would be 60=0.4x, with x being the cups of peaches.
