The answer is 3)
Just sub any number you want into the equation and calculate it.
For example of 3）

Answer:

see below

Step-by-step explanation:

It is easiest to compare the equations when they are written in the same form.

The first set can be written in slope-intercept form.

y = 2x +7

y = 2x +7 . . . . add 2x

These equations are identical, so have infinitely many solutions.

The second set can be written in standard form.

y +4x = -5

y +4x = -10

These equations differ only in their constant, so have no solutions.

The third set is already written in slope-intercept form. The equations have different slopes, so have exactly one solution.

What is the area of the square? Help me pls

Allushta [10]

Answer and Step-by-step explanation:

First, we need to find out the circumference of the circle.

We know that the circle has a radius of 1, and that we are finding the circumference. We'll use the circumference equation of a circle.

2 $\pi$ r

Plug in 1 for r.

$2\pi (1)$ = $2\pi$ = circumference of circle

Now, multiply the answer (the circumference) by 4 to get the perimeter of the square.

$2\pi$ x 4 = $8\pi$ = perimeter of square

Now, divide the perimeter by 4 to get what the side of the square is.

$8\pi$ ÷ 4 = $2\pi$

Now, multiply $2\pi$ by $2\pi$ (side times side) to get the area.

$2\pi$ x $2\pi$ = $4\pi$

The answer is A. $4\pi$
