Elle ordered some large pizzas and some medium pizzas for a party. In all, she ordered 18 pizzas. Large pizzas cost $14, and med

ium pizzas cost $10. In all, she spent $204. Determine if each equation is a part of the system of equations that can be used to find the number of each type of pizza that was ordered. The variable x represents the number of large pizzas, and y represents the number of medium pizzas.

L+m=18, l=18-m

14l+10m=204 using l found above in this we get:

14(18-m)+10m=204

252-14m+10m=204

252-4m=204

-4m=-48

m=12, since l=18-m

l=6

So Elle ordered 6 large and 12 medium pizzas.

In the graph, the area below f(x) is shaded and labeled A, the area below g(x) is shaded and labeled B, and the area where f(x)
mamaluj [8]

Answer:

First option:  \left \{ {{y\leq -2x + 3} \atop {y \leq x + 3}} \right.

Step-by-step explanation:

The missing graph is attached.

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope and  "b" is the y-intercept.

We can observe that:

1. Both lines have the same y-intercept:

b=3

2. The lines are solid, then the symbol of the inequality must be \leq or \geq.

3. Since both shaded regions are below the solid lines, the symbol is:

\leq

Based on this and looking at the options given, we can conclude that the graph represents the following system of inequalities:

\left \{ {{y\leq -2x + 3} \atop {y \leq x + 3}} \right.

Enter an equation in point-slope form for the line.<br> Slope is 9 and (−3, −1) is on the line.
Korolek [52]

Answer:

y+1=9(x+3)

Step-by-step explanation:

Since the equation for point slope form is y-y₁=m(x-x₁)

enter the given points (-3,-1)

y-(-1)=9(x-(-3))

y+1=9(x+3)           <-- point slope form
