What math properties are these equations?

1 answer:

7 0

Hmm. This is a bit difficult, but they all have to do with multiplication. The first and third equations have to belong to commutative property of multiplication, because you can switch the order of them and still get the same answers. The second question would be associative property of multiplication, because there are parenthesis around two numbers and you can move the parenthesis without switching the order of the numbers, while still getting the same answer.

Pablo graphs a system of equations. One equation is quadratic and the other equation is linear. What is the greatest number of p

Nady [450]

For this case we have the following type of equations:
Quadratic equation:
$y = ax ^ 2 + bx + c
$
Linear equation:
$y = mx + b
$
We observe that when equating the equations we have:
$ax ^ 2 + bx + c = mx + b
$
Rewriting we have:
$ax ^ 2 + (b-m) x + (c-b) = 0
$
We obtain a polynomial of second degree, therefore, the maximum number of solutions that we can obtain is 2.
Answer:
The greatest number of possible solutions to this system is:
c.2

Answer:

20x+50

Step-by-step explanation:

Let x represent the number of days he has the car

20x+50

It is 20x, because it costs 20 dollars for each day he has the car, and +50, because there is a fee, regardless of how many days he has the car.
