Explanation: Algebraic expression is a mathematical expression that consists of variables, numbers, and operations.
8: ← Variable
(x): ← Operation
5: ← Constant
Example: x+12
The variable in the expression is x.
The operation in the expression is +.
The constant in the expression is 12.
Hope this helps!
Thanks!
Have a great day!
It seems to me c could be any number besides 2,12,-1 or 0
why?
a function is defined by each x value having a single y value
if an x value has two numbers such as (0,1) (0,2) than it is not a function.
the vertical line test is great for seeing if something is a function becasue it determines if each x value has one y value.
Answer and Step-by-step explanation:
A system of equations is a group of equations that need to be manipulated in some way that will figure out the values of the variables.
The most common system of equations seen is a system of linear equations, which means that the degree of the variables is no more than 1. These can be solved using elimination, substitution, or even graphing, if applicable.
Hope this helps!
Answer:
A system of equations is 2 or more equations that need to be solved. When you solve a system of equations, the answer is where the equations intersect on a graph. Sometimes there is 2 solutions (equations intersect twice), 1 solution (equations intersect once), no solution (equations don't intersect), or infinite solutions ( equations are the same).
They are usually solved using substitution, elimination, or simply looking at a graph to see where the lines intersect.
Some examples:
2x+3y=15
x-3y=3
y=x^2+1
2x-y= -4
