Given the system
Irina-Kira [14]

we have

y > -2 x + y < 4

using a graph tool

see the attached figure

The shaded area is the solution of the system

<u>Part 1) </u>Name an ordered pair that is a solution to this system and explain how you know that this is a solution point

Let

A ( -40,20)

The point A is solution of the system because the point lie on the shaded area

<u>Check</u>

If the point A is solution of the system must satisfy both system inequalities

point A

x=-40

y=20

substitute

y > -2-------> 20 > -2-------> is ok

x + y < 4----> -40+20 < 4-----> -20 < 4-----> is ok

therefore

<u>the answer Part 1) is</u>

The point A is a solution of the system

Part 2) Name an ordered pair that is not a solution to the system and explain how you know that it is not a solution

Let

B(20,20)

The point B is not solution of the system because the point not lie on the shaded area

<u>Check</u>

If the point B is not solution of the system must not satisfy both system inequalities

point B

x=20

y=20

substitute

y > -2 -------> 20 > -2-------> is ok

x + y < 4---->20+20 < 4-----> 40 < 4------> is not ok

therefore

<u>the answer part 2) is</u>

The point B is not a solution to the system

Find x in This equation.<br> 2x+2=-4(x-5)
san4es73 [151]

Hey there!

2x + 2 = -4(x - 5)

2x + 2 = -4(x) - 4(-5)

2x + 2 = -4x + 20

ADD 4x to BOTH SIDES

2x + 2 + 4x = -4x + 20 + 4x

SIMPLIFY IT!

6x + 2 = 20

SUBTRACT 18 to BOTH SIDES

6x + 2 - 2 = 20 - 2

CANCEL out: 2 - 2 because it give you 0

KEEP: 20 - 2 because it help solve for the x-value

NEW EQUATION: 6x = 20 - 2

SIMPLIFY IT!

6x = 18

DIVIDE 6 to BOTH SIDES

6x/6 = 18/6

CANCEL out: 6/6 because it give you 1

KEE: 18/6 because it help solve for the x-value

NEW EQUATION: x = 18/6

SIMPLIFY IT!

x = 3

Therefore, your answer is: x = 3

Good luck on your assignment and enjoy your day!

What are two consecutive integers whose sum is -97
zimovet [89]

Answer:

-48 and -49

Step-by-step explanation:

n + n + 1 = -97

2n + 1 = -97

2n + 1 - 1 = -97 - 1

2n = -98

2n/2 = -98/2

n = -49

 -49 + 1 = -48

 -49, -48

How to find the circumference of a circle that is 42m and has diameter
Nitella [24]

Answer:

Circumference of the circle is 131.88m

Step-by-step explanation:

we have to find the circumference of the given circle.

Given:

                     Diameter=42 m

          \\diameter=2*radius\\42 =2*radius\\radius=42/2\\radius=21 m

Circumference of a circle= 2\pi r

                          =2*\pi *21\\=2*3.14*21\\=42*3.14\\=131.88

So, the circumference of the circle is 131.88m
