Answer:
B ;))))))
Step-by-step explanation:
Answer:
I think its wrong. For g(5)=(5/5)^2=1 and in your graph is something close to 3. The correct graph for 
is
In this item, we equate the functions as stated.
f(x) = g(x)
3x - 23 = -4.5x + 7
Transpose all the terms with variables to one side of the equation and all the constants to the other side. This is shown below.
3x + 4.5x = 7 + 23
Combine like terms,
7.5x = 30
Divide both sides of the equation by 7.5.
(7.5x)/7.5 = 30/(7.5)
<em> x = 4</em>
Therefore, the solution to this item is that x = 4.
The answer is Net A with a surface area of 390 square inches
Answer: The function that models the distance they drive is
f(x) = 50x + 20 where x is the time in hours
reasonable domain: 0 ≤ x ≤ 3
Step-by-step explanation:
examples:
95 = 50(1.5) + 20 After driving another hour and a half, they will have driven a total of 95 miles.
120 = 50(2) + 20 This means that after 2 more hours they will reach their destination.
There is a little ambiguity in the question. The function could be written as if they are starting out. f(x) = 50t
20 = 50(.4) At 50 mph it took .4 hours to go 20 miles.
120 = 5(2.4) The whole trip took 2.4 hours.
