Q1

Q2

Answer:

B). (-4, 5)

Step-by-step explanation:

-2x – 3y = -7 | ×2 |

-4x + y = 21 | ×1 |

-4x – 6y = -14

-4x + y = 21

____________ --

-7y = -35

y = -35/-7

y = 5

-4x + y = 21

-4x + 5 = 21

-4x = 21 - 5

-4x = 16

x = 16/-4

x = -4

The equation that is equivalent to x + 8 = 21 is (x + 8) × 4 = 21 × 4

Given the equation

To get a similar expression we will either subtract, multiply, divide or add the same constant to both sides of the equation

Multiplying both sides by 4 will give:

Hnce the equation that is equivalent to x + 8 = 21 is (x + 8) × 4 = 21 × 4

Answer:

to graph an inequality you need a variable. please rewrite your question.

Answer:

A) -4

Step-by-step explanation:

There are two ways of solving this:

1.) Plugging in the answer choices

Since the equation needs to be equal to or less than 1 (this is due to the less than or equal to sign:  ≤)

You will then set the equation: -2x-6 ≤ 1

You will then take each answer choice and plug it into the original equation.

Plug in -4:  -2(-4)-6 ≤ 1   this will result in 2 ≤ 1

Plug in -3:   -2(-3)-6 ≤ 1 this will result in 0 ≤ 1

Plug in -2:   -2(-2)-6 ≤ 1 this will result in -2 ≤ 1

Plug in -1:     -2(-1)-6 ≤ 1 this will result in -4≤ 1

The only one that is not true is when you plug in x=-4 into the equation -2x-6.  This results in the equation being equal to 2.  2 is not less than 1, making the equation false.

Method 2: Solving the inequality

You can essentially solve for x like a normal inequality.

Instead of solving for -2x-6 = 1, we are doing -2x-6 ≤ 1.

First: Add 6 to the right side

-2x ≤ 1+6 --->>>>  2x ≤ 7

Second:  Divid both sides by -2

***Note: When you divivde by a negative when solving an inequality, you must switch the sign. ***

x ≥ -3.5   (hence the sign swtiches from ≤ to ≥ since we divided by a negative value in the equation)

x ≥ -3.5 states that any number greater or equal to -3.5 will work.  -4 is less than -3.5, thus it will not satisfy the inequality.

Answer:

Step-by-step explanation:

you can think is a big rectangle with area

A= 5*6= 30

then subtract the area of the 2 triangles

30- 2(b*h/2) = 30- 6*2 = 30 -12 = 18 units ²

(b-7)m=r

Use the distributive property to multiply b-7 by m.

bm-7m=r

Add 7m to both sides.

bm=r+7m

The equation is in standard form.

mb=7m+r

Divide both sides by m.

mb/m = 7m+r/m

Dividing by m undoes the multiplication by m.

b= 7m+r/m

Divide r+7m by m.

b= r/m+7

Answer:

37/400

Step-by-step explanation:

Sorry if I'm wrong UwU

The 9.25% as a fraction in simplest form is 37/400 after simplifying the 9.25%.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

We have:

9.25%

We have to write the 9.25% as fraction in the simplest form.

= 9.25%

= 9.25/100

= 0.0925

= 925/10000

= 37/400

Thus, the 9.25% as a fraction in simplest form is 37/400 after simplifying the 9.25%.
