Answer:
Step-by-step explanation:
3x + 2·10 + 1·15 = (3x + 35) dollars
The number of pizzas you must order for the price to be the same is 5
<h3>How many pizzas must you order for the price to be the same?</h3>
Bob's Pizza charges = $12 for each supreme pizza
This can be represented as
y = 12x
For Mike's Pizzeria, we have
y = 8x + 20
Substitute y = 12x in y = 8x + 20
12x = 8x + 20
Evaluate the like terms
4x = 20
Divide by 4
x = 5
Hence, the number of pizzas you must order for the price to be the same is 5

Answer:
27 by 27
Step-by-step explanation:
Let the sides be x and y. The problem is essentially asking:
Given 2(x+y)=108, maximize xy.
We know that x+y=54. By the Arithmetic Mean - Geometric Mean inequality, we can see that
. Substituting in x+y=54, we get
, meaning that
. Equality will only be obtained when x=y (in this case it will generate the maximum for xy), so setting x = y, we can see that x = y = 27. Hence, 27 is the answer you are looking for.
Answer:
A. The graph has two zeroes.
Step-by-step explanation:
A <em>zero of a polynomial</em> is a value of x that makes the polynomial equal to zero.
In other words, it is <em>an x-intercept</em>.
The graph crosses the x-axis twice, so there are two zeroes.
