one step Equations
a - (-163) = -392
Which is -555
what is a system of equations
a system of equations is a group of two or more equations that contain the same set of variables.
12(x + 3) - 3x = 117
x = 9
Is it a function?
Which is no because x repeats
4a - 10 = 42
= 13
c/-0.29 = 5.5
which is -1.595
More than one equation to be solved at the same time is know as this
System of Equations
3 + 5(a + 4)
3 + 5(a + 4)
A relation that assigns exactly one value in the range to each value in the domain
which is a function
2x + 9 > 25
is x > 8
x + 36 = -100
-136
what are the solutions of system of equations
A solutions to a system of equations are the point where the lines intersect. There are four methods to solving systems of equations: graphing, substitution, elimination and matrices.
-2(x - 6) + 7 = 35.
x = - 8
What is the name of the method used to determine whether a graph is a function or not
Vertical Line Test
When solving 2-Step equations, which operations should you do first
addition and subtraction
-21y = -756
which is 36
The solution to the system of equations:
y - 3x = 3
y = 3x - 2
There is no solution
10 + 3(x + 2) = 31
x=5
Is it a function? {(2, 3), (4, 5), ( -2, 6)}
What is yes because x does not repeat
4x + 17 > 37
which is x > 5
-80 = x/15
which is -1200
The solution to the system
t + u = 12
t = (1/3)u
(3, 9)
3 = x/25 + 6.
x = -75
Linear Function, Nonlinear Function, or NOT a function?
2x - 3y = 18
linear function
85 = 4d + 5
= 20
