Answer:
(B) There are 12 glasses for every 1 table
Step-by-step explanation:
Since the graph is a perfectly straight line, we can assume that there is a proportional relationship. Looking at the axes confirms this. For the 1st table, there are 12 glasses, for the 2nd, there are 24, and so on.
So, we can see that the proportion between tables and glasses is 12:1. For every 1 table, 12 glasses must be placed on it.
So, if they gave this to you as a table or a formula, you'd simply need to multiply 12 by the number of tables to see how many glasses are required.
f(5) means that x=5
Now, we solve 5x-3 because we know what x is.
5(5)-3
25-3
22
F(5)=22

Answer:

Step-by-step explanation:
step 1
<em>Find the equation of the solid line with positive slope</em>
we have the points
(0,4) and (-2,0)
<em>Find the slope</em>

The equation of the line in slope intercept form is equal to

we have

substitute

step 2
<em>Find the equation of the inequality with positive slope</em>
we know that
The solution of the inequality, is the shaded area below the solid line
so
The equation of the inequality is
----> inequality A
step 3
Find the equation of the line with negative slope
we have the points
(-6,0) and (-4,-2)
<em>Find the slope</em>

The equation of the line in slope intercept form is equal to

we have

substitute

solve for b


so
The linear equation is

step 4
<em>Find the equation of the inequality with negative slope</em>
we know that
The solution of the inequality, is the shaded area above the solid line
so
The equation of the inequality is
----> inequality B
therefore
The system of inequalities is
----> inequality A
----> inequality B
