2x+12=4x
Make two equations, and solve for x.
1. 2x+12= 4x 2. 2x+12= -4x subtract 2x from both sides
12=2x 12= -6x
6=x -2=x
plug in the x values to know if they are the solution for the eqaution.
2(6) +12= 4(6) 2(-2) +12= -4(-2)
12+12= 24 -4+12=8
24=24 8=8
The equation is true, it's all real numbers or infinite solutions.
Answer:
x 2-2 3-3
y 5 5 7 7
Step-by-step explanation:
Each domain, or x value, can only be matched with one y value, so given this, the third one is the answer since every domain is only matched with one range, or in other words, there are no repeating domains in on the x row of the table.
Answer:
y=8/5x + 18/5
Step-by-step explanation:
subtract 8x on both sides which ends up looking like:
-5y = 18 -8x
divide -5 on both sides which ends up like:
y= 8/5x - 18/5
then u simplify, but there's not need for that because it's already simplified.
Answer:
22.32
Step-by-step explanation:
First you subtract what in the parenthesis 10.75 minus 3.55 equals 7.2
Then you multiply 7.2 by 3.1 which equals 22.31
remember PEMDAS!
