Answer: f(x) = 4x + 3
g(x) = -2x + 5
(f · g)(5) = (4(5) + 3)(-2(5) + 5)
(f · g)(5) = (20 + 3)(-10 + 5)
(f · g)(5) = (23)(-5)
(f · g)(5) = -115
Answer:
about 154.3
Step-by-step explanation:
Answer:
<h2>
X = 4.5</h2>
Step-by-step explanation:
So we have two equations.
y=35x+40
y=40x+17.5
We want to find the coordinates in which they intersect.
BUT They never intersect, They are parallel to each other leaving us with a
NO SOLUTION
When you are trying to solve for x you want to get rid of the y's and simply put on your paper: 35x+40 = 40x+17.5
Then you distribute, in which I am not going to show because that too many steps lol. But you'll get:
x=4.5
Answer:
The maximum width of the pool must be 38 ft
Step-by-step explanation:
Let
y -----> the length of the swimming pool
x ----> the width of the swimming pool
The perimeter of the swimming pool is
we have
substitute
Remember that
The perimeter of the pool must be no more than 120 feet
so
The inequality that represent this scenario is
Solve for x
therefore
The maximum width of the pool must be 38 ft
Answer:
18 gallons
Step-by-step explanation:
divide 300 by 15 you 150 or 15 again then add 1 gallon per every twenty miles
thus your answer is 18 gallons of gas
