**Answer:**

linear

**Step-by-step explanation:**

Answer: (x-2)(x-1)(x+1)

Step-by-step explanation: Roots are where the graph hits the x-axis. So just like if you had the equation (example) x^2 + 4x + 4 and you were to factor it out to get (x+2)(x+2) you could then set x+2=0 to get the root x=-2. Think of your problem like as if someone has already done the factoring for you. Now all you have to remember is that the answer will have the opposite sign with in the parentheses because its like you’re adding or subtracting it to the x to get zero on other side of the equal sign... x=3 ——> x-3 = 0

**Answer:**

from what diagram

**Step-by-step explanation:**

**Answer:**

x= 1 , y=4

**Step-by-step explanation:**

x-y= -3 => Equation 1

x+5y= 21 => Equation 2

**<u>Substitut</u>****<u>ion</u>****<u> </u>****<u>Method</u>****<u>:</u>**

<u>Substitu</u><u>te</u><u> </u><u>Equation</u><u> </u><u>1</u>=>

x=y-3 <= Equation 3

Put x=y-3 in Equation 2:

x+5y=21

( y-3)+5y=21

y-3+5y=21

6y-3=21

6y=21+3

6y=24

y=24÷6

y=4

Put y=4 in Equation 1:

x-y= -3

x-4=-3

x=4-3

x=1

Hope this helps :)

**Answer:**

117 grams

**Step-by-step explanation:**

So this is a oddly phrased question but I believe I understand it. You need to find 10 percent of 1170 grams and that it 117. And for you information I did use calculator to prevent error so don't worry about that.
