Step-by-step explanation: To understand the commutative, let's look at the following problem.

2 + 3 = 3 + 2

The problem shown above demonstrates the commutative property of addition. In other words, the commutative property of addition says that changing the order of the addends does not change the sum.

For example here, we can easily see that the sum of 2 + 3 gives us 5 is equal to the sum of 3 + 2 which is also 5.

In more general terms, the commutative property of addition can be written as a + b = b + a where a and b are each variables that can represent any number.

What is the value of x in the equation 8x – 2y = 48, when y = 4?

morpeh [17]

Answer:

x = 7

Step-by-step explanation:

since we know y = 4, we can plug this into the equation to find x

8x - 2y = 48

8x - 2(4) = 48

8x - 8 = 48

8x = 56

x = 7

Which equation represents the function shown on the graph?<br> y=1/4x<br> y=1/2x<br> y=2x<br> y=4x

Alexus [3.1K]

Y=4x. y=mx+b m=slope b=y intercept m=4 because it goes up 4 over 1 and 4/1=4 b=0 because it started at 0, making the equation y=4x+0 or just y=4x
