Answer:
5.98
Step-by-step explanation:
2.99 * 1= 2.99
2.99+2.99= 5.98
First you had to multiply 2.99 by 1 because 100% in decimal is 1.
You get 2.99 and you add it to the original price.
And that is how you get 5.98
Answer:
Your answer: 87
Step-by-step explanation:
Since you are given what both variables are in the equation, this problem requires you to plug it in.
12(6)+3(5)= ?
You can either do this in a calculator, or do this one step at a time.
12(6)=72
3(5)=15
72+15=87
Answer:
Step-by-step explanation:
A quadratic in factored form is usually expressed as: 
where the sign of a and b depends on the sign of the zero. And I said "usually" since sometimes the x will have a coefficient. Anyways in the quadratic there are two zeroes at x=-1 and x=3. This can be written as: 
. Notice how the signs are different? This is because when you plug in -1 as x you get a factor of (-1+1) which becomes 0 and it makes the entire thing zero since when you multiply by 0, you get 0. Same thing for the x-3 if you plug in x=3. Now a is in front and it can influence the stretch/compression. To find the value of a, you can take any point (except for the zeroes, because it will make the entire thing zero, and you can technically input anything in as a)
I'll use the point (1, -4) the vertex
-4 = a(1+1)(1-3)
-4 = a(2)(-2)
-4 = -4a
1 = a. So yeah the value of a is 1
So the equation is just:
<h3>your answer is 20: 1 2 </h3>
