Item 8 factor −5 out of −10a−25.

egoroff_w [7]

To factor a number out of an expression means to divide each term of the expression by that number.

So, if you want to factor $a$ from the expression $x+y+z$ , you'll write it as

$a\left(\dfrac{x}{a}+\dfrac{y}{a}+\dfrac{z}{a}\right)$

So, in your case, when you divide both terms by -5 you get

$-10a \div (-5) = 2a,\quad -25\div (-5) = 5$

So, the expression becomes

$-10a-25 = -5(2a+5)$

The amount of money, y, pizzeria J makes by

Degger [83]

Answer:

Pizzeria J

Step-by-step explanation:

Pizzeria J makes

y = 14x

Let x = 1, for 1 pizza. Then,

y = 14 × 1

y = 14

At pizzeria J, 1 pizza costs $14.

In the equation y = 14x, the slope, 14, is the cost per pizza.

Now we find the slope of the graph for pizzeria W.

The x-axis is the number of pizzas.

For x = 1, y = 11.

The slope is 11, so the price per pizza is $11.

Answer: Pizzeria J
