Question 1: x+2 = 8 doesn't belong in the given equations.

Question 2: The possible values for y are 0,1 and 2

Step-by-step explanation:

Question: Which one doesn't belong?

We will solve each equation one by one to get which equation doesn't belong with others

So,

x+4 = -2\\x+4-4 = -2-4\\x = -6

x+5 = -1\\x+5-5 = -1-5\\x = -6

x+2 = 8\\x+2-2 = 8-2\\x = 6

3-x=9\\3-x-3 = 9-3\\-x = 6\\x = -6

Hence,

x+2 = 8 doesn't belong in the given equations.

Question 2:

Given equation is:

x+y = 5

It is given that the values of x will be greater than 2 and less than 6 so values of x can be 3,4 and 5

So,

3+y = 5\\y = 5-3\\y = 2\\\\4+y = 5\\y = 5-4\\y = 1\\\\5+y = 5\\y = 5-5\\y = 0

Hence,

The possible values for y are 0,1 and 2

So,

x+2 = 8 doesn't belong in the given equations.

The possible values for y are 0,1 and 2

Answer:

Muliple choice A.

Step-by-step explanation:

Here, we have two sets that need to be subtracted from eachother. So, first we start off like we're reading a book. From top to bottom, from left to right. And we need to match up the numbers together to subtract. (i.e. the top left from both set A and B will be 5 and 1, so we subtract these. And we do that for all the numebrs.

What is 3x-4y=4 in linear equations
KengaRu [80]
Your equation is a linear equation because it has a constant, and it has variables. And it does not have something like x^2.

However, if your question wants it in slope-intercept format, which is y=mx+b

Then:

3x-4y = 4

We can add 4y to both sides
3x = 4+4y

Subtract 4 from both sides
3x-4 = 4y

Then we divide by 4
\frac{3}{4} x -1=y

So 3x-4y=4 in slope-intercept format would be y =\frac{3}{4} x -1
