Solve the inequality
2x<3+5x
x>-1
What is the graph of x>,=1 (greater than or equal to)
Closed circle on 1, pointing right
2(x+3)+2x>4
Distribute 2 into (x+3)
x-b=a
x=a+b
3x/y
-2(3x+4)>4
x<-2
What is the graph of 2x>16
open circle on 8, pointing right
What step do we take to eliminate something we are adding. (Ex: x+2>4)
Subtract (the inverse operation to addition)
solve for y
z=xy
y=z/x
using a=4 and b=-1 evaluate the equation
a2+3b
13
6x-4+3x+10>8x+10-2x-5
-1/3<x
what is the graph of
2(x-5)>3(x+2)
What is the first step we take to solve this inequality?
(x+2)/3>10
multiply both sides by 3
Solve the equation:
2(4x-2)+10x=32
x=2
the quotient of a number squared and 4
x2/4
(x+2)/3>6
x>16
What is the graph of
2x-10<,=4
(less than or equal)
closed circle on 7 pointing left
When do we flip/ reverse the inequality symbol?
When multiplying or dividing by a negative number
What is the solution (if any) to the following equation:
2(x+3)=2x+6
6=6 which means there are infinite solutions
Given x=2 and y=-2 evaluate the following equation
(-y+3x+10)/4
4
4(-x+3)<12(2x+4)
x>-5/4
What is the graph of x=0
a closed circle on 0. NO arrows. This is just a point.
What is the inverse operation for multiplication?
Dividing both sides of the inequality/ equation.
What is the solution (if any) to the following equation:
3(2x−4)+5=2(3x−1)+3
-7=1 which means there are no real solutions to this equation
If Bob (b) is 5 inches taller than Alice (a). Write an expression to describe Alice's height.
a=b+5
(Alice=Bob+5 inches)
