Answer:

Option A

Step-by-step explanation:

we have

y=2x+1 ------> equation A

y=-x+4 ------> equation B

we know that

The solution of the system of equations is the intersection point both graphs

using a graphing tool

The intersection point is (1,3)

therefore

The solution of the system of equations is the point  (1,3)

The graph in the attached figure

How do I do pre-Algebra???
Lana71 [14]

Hey there!

The main concept of pre-algebra is solving equations for variables in them.

For example, let's say you have the algebraic equation below.

x+1=3

With algebra, you need to figure what x is equal to. To do so, you will use inverse operations on both sides of the equation to isolate x one side, showing what it is equal to.

We would subtract 1 to both sides to isolate x on one side.

x+1-1=3-1

As you can see, +1-1=0, therefore, this would give us x+0, or just x. Now it is isolated and will show us what it is equal to.

x=3-1

x=2

Therefore, in our equation x+1=3, x would be equal to 2.

I hope this explanation helps! Have a great time here at Brainly!

Estimate the difference of the decimals below by rounding to the nearest whole number. 23.827
iragen [17]

Step-by-step explanation:

The key rule is: to round up the number one digit to the left has to be the number 5 or more, else it rounds down.

23.827 rounds up because the 8 is more than 5.

1.218 rounds down because 2 is less than 5.

24-1= 23
