PLEASE HELP
Annie wrote the following steps to solve a pair of equations:

Step 1: y = −x − 5
y = 2x + 2

Step 2: 2y = −2x −10
y = 2x + 2

Which of the following shows the correct next step to solve the equations by eliminating x?
3y = –5
3y = –8
3y = –12
3y = –20

Option B: is the correct next step to solve the equations by eliminating x

Explanation:

Given that the steps to solve the pair of equations.

Step 1: and

Step 2: and

We need to determine the next step to solve the equations by eliminating x.

The solution can be determined by adding the two equations in step 2.

Thus, we have,

Simplifying the terms, we have,

Adding the like terms, we get,

Thus, is the correct next step to solve the equations by eliminating x.

Hence, Option B is the correct answer.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
