Answer:
This is a function because each x value has a different y value. If one of x values would of had two different y values then it would of not have been a function
Step-by-step explanation:
Answer:
The correct options are 1, 2, 4 and 6.
Step-by-step explanation:
The given expression is

To subtract like term subtract like terms, subtract the coefficients, not the variables.
Therefore option 1 is correct.
Like terms are terms that contain the same variable, raised to the same power. For example: 3xy and 5xy, 4x² and 3x².
Therefore, option 2 is correct.
Using distributive property we get


Only combine terms which contain the same variable.
Therefore option 4 is correct.


The simplified expression is -4x-3y+3z. Therefore option 6 is correct.
Answer:
C x=55
Step-by-step explanation:
the angles of a trianlge add up to 180
the unmarked angle is also 35 because of the same side length
35+35=70
180-70=110
BUT 2x=110 so x=55
P.S Can I get brainlist?
I think it is 1.3 and how u figure it out is tenths and haves charts like me
199.53 is correct. Brainliest?
