FOIL: first term, outer term inner term, last term
First, find the function that represents x and y.
x is the number of 8 oz jars
y is the number of 16 oz jars
function: 8x + 16y = 240
x-intercept: y = 0 => 8x = 240 => x = 30 => (30,0)
y-intercept: x = 0 => 16y = 240 => y = 15 => (0, 15)
Answer: (0,15) and (30,0)
Answer:
The solution to the system of equation would be the two order pairs (2,10) and (-1,16)
Explanation:
The solution means the value of x that satisfies both equations.
Therefore, we will equate the two equations given and solve for x.
The first is: y = x^2 - 3x + 12
The second is : y = -2x + 14
Equate both and solve for x as follows:
x^2 - 3x + 12 = -2x + 14
x^2 - 3x + 2x + 12 - 14 = 0
x^2 - x - 2 = 0
(x-2)(x+1) = 0
either x = 2 and y = (2)^2 - 3(2) + 12 = -2(2) + 14 = 10
or x = -1 and y = (-1)^2 - 3(-1) + 12 = -2(-1) + 14 = 16
Therefore, the solution to the system of equation would be the two order pairs (2,10) and (-1,16)
Hope this helps :)
Methods of describing a set involve using a roster or set-builder notation to outline it.
<h3>What are the methods of describing a set</h3>
The two methods of describing a set are:
- roster method
- set- builder notation method
Roster method describes a set by listing all its elements, separated them by commas and enclosed within brackets.
Set- builder notation method describes a set by describing its elements using mathematical statements
Therefore, methods of describing a set involve using a roster or set-builder notation to outline it.
