Answer:
Step-by-step explanation:
Well.. First of all, the question says that we are working with a rectangle..
So, the rectangle has a length and width. I'll call them L and w.
Look at this phrase: " length that is one foot less than twice its width"
it means, in a algebraic language: L = 2w - 1
Let's analysis the next phrase: "it the area of the rectangle is 91 square feet"
So, A = 91 ft²
But you have to remember that the rectangle area is a product of L and w.
L x w = 91
They are the following equations that you could be used to solve the system of equations.
Now, you have a system of equations and I suggest you to solve it using the substituition method.
L = 2w - 1
L x w = 91
Answer:
x= -1
-1 =4

Answer:
30
Step-by-step explanation:
The ring operator signifies a composition of functions. The composition is evaluated right-to-left. That means the composition ...
should be interpreted to mean ...
___
To evaluate f(g(6)), we first evaluate g(6):
g(6) = 6² -5 = 31
Then we evaluate the function f using that as its argument:
f(31) = 31 -1 = 30
f(g(x)) = 30
Based on the advertisement seen by Dazuri, the cost of each soccer ball is $22.50
<h3>How to find the cost?</h3>
The advertisement says that the original cost of the ball is $30 but there is a 25% discount.
The price of each soccer ball is therefore reduced by the 25% discount on the ball.
The amount that each soccer ball costs is therefore:
= 30 - ( 30 x 25%)
= 30 - 7.5
= $22.50
Rest of the question is:
Soccer balls on sale at a 25% discount. Prices go back to $30 in a week. Don't miss out.
