Answer:
I would just guess, but if i were to actually think about it, i would think C. I hope it helps, and blame it on me if you fail.
Step-by-step explanation:
Answer:
x < -16/3 or x > 4
Step-by-step explanation:
This is split into two inequalities: 3x + 2 > 14 and -(3x + 2) > 14.
3x + 2 > 14
3x > 12
x > 4
-(3x + 2) > 14
3x + 2 < -14
3x < -16
x < -16/3
You have the ratio set up correctly:
2x+2/12 = x+3/21
Now cross multiply:
2x+2 * 12 = x+3 * 21
Simplify:
24x + 24 = 21x + 63
Subtract 24 from each side:
24x = 21x + 39
Subtract 21x from each side:
3x = 39
Divide both sides by 3:
x = 39/3
x = 13
We want to study the function represented with the given graph.
We will find that the constant of proportionality is r = $12.5
And the equation is:
c = $12.5*p
First, let's define a general proportional relationship.
It is written as:
c = r*p
Where r is the constant of proportionality.
a) Here we just want to get the value of the constant of proportionality, to do this, we just need to find a point on the graph.
By looking at the graph, we can see that 6 pizzas cost $75, then we can replace that in the proportional relationship to get:
$75 = r*6
$75/6 = r = $12.5
Then the proportional relationship is:
c = $12.5*p
