The slope of the line is going to be 0.25m, since the 0.25 is the cost per mile and will change as more miles are added.
the delivery fee is always going to stay the same, so that will act as the “y intercept”
t = 0.25m + 3
Answer:
8/5
Step-by-step explanation:
First find h(-3)
h(-3)= 4-(-3) = 4+3 = 7
Then take this result and find g(h(-3)) = g(7)
g(7) = (7+1)/( 7-2) = 8/5
h(x) = 3x + 5
h(a) = 27
We can write this as 3a + 5 = 27
Now, we just need to solve for a.
<em><u>Subtract 5 from both sides</u></em>
3a = 22
<em><u>Divide 3 from both sides.</u></em>
a = 7.33
Now, let's plug 7.33 back into the original equation.
3 * 7.33 + 5 = 27
22 + 5 = 27
27 = 27 √ this is correct
To find the cross product, you can set this up as a proportion. Please see the attached paper for one of the proportions you could use.
You would then multiply the numbers that are diagonal from each other.
You would have 21(8) = 12x or
168=12x.
The answer is 525
2/3 of residential = 350 customers. so you divide 350 by 2. Which is 175. 175•3= 525
