2x + 4 = 0
find the value of x

Answers

Answer 1

Answer:

[tex]x=-2[/tex]

Step-by-step explanation:

[tex]2x + 4 = 0[/tex]

Subtract 4 from both sides:-

[tex]2x+4-4=0-4[/tex]

[tex]2x=-4[/tex]

Divide both sides by 2:-

[tex]\frac{2x}{2}=\frac{-4}{2}[/tex]

[tex]x=-2[/tex]

[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]

[tex] \sf2x+4=0[/tex]

Subtract 4 from both sides. Anything subtracted from zero results in its negation.

[tex] \sf2x=-4 [/tex]

Divide both sides by 2.

[tex] \sf \: x=\frac{-4}{2} \\ [/tex]

Divide -4 by 2 to get -2.

Find the value of 9w + 1 given that -5w -5 = 5

Answers

Answer:

-17

Step-by-step explanation:

First, let's see what the value of w is, by solving -5w - 5 = 5.

-5w - 5 = 5            Add 5 on both sides.

-5w = 10                Divide -5 on both sides.

w = -2

Now, we know that w is equal to -2, let's plug it in to find the value.

9(-2) + 1                 Distribute.

-18 + 1                    Add.

AC = 8, AB = 2x + 20, and BC = 2x + 24. Find x.

Answers

Answer:

Answer: x is -9

Step-by-step explanation:

If it's a line AC with a point B between;

AC = AB + BC

substitute in terms of x :

[tex]8 = (2x + 20) + (2x + 24)[/tex]

group x terms in a same bracket, and constants in their bracket

[tex]8 = (2x + 2x) + (20 + 24) [/tex]

operate the brackets:

[tex]8 = 4x + 44[/tex]

subtract 44 from both sides:

[tex]8 - 44 = (4x + 44) - 44 [/tex]

simplify:

[tex] - 36 = 4x[/tex]

divide all sides by 4:

[tex] \frac{ - 36}{4} = \frac{4x}{4} \\ \\ x = - 9[/tex]

Answers

Answer:

(0,-1) I could be wrong

Step-by-step explanation:

Answer:

Step-by-step explanation:

-2x+9y=-9 (solve for x)

-2x= -9y-9

X = - 9y/-2 - - 9/2. X = 9y/2 + 9/2

9(9/2y+9/2)-2y=2

81y/2 + 81/2 - 2y = 2

81y/2 - 2y = 2 - 81/2. 81/2 - 2 = 77/2 and -81/2 +2 = -77/2

77/2 y = - 77/2

y = (-77/2)/(77/2)

745/999

Answers

If x = 745/999, then

999x = 745

1000x - x = 745

This equation tells us that the fractional part of 1000x and x cancel upon subtracting. This means the block of repeating digits must be 3 digits long.

To verify this, suppose we write x = 0.yyy… , where y consists of 3 digits. Then

1000x = y.yyy…

1000x - x = y.yyy… - 0.yyy…

999x = y

x = y/999

which means y = 745.

Answer:

3 digits

Find the sales tax and total cost of a Sony Playstation that costs $151.99. The tax rate is 4%. Round your answer to the nearest cent.

Answers

4% of 151.99 is 6.0796 rounded is 6.10

Total would be $158.07

To calculate slaes tax and total cost, take the price (151.99) and multiply by tax rate, then add them together.

4%= .04

So Price (151.99) times tax(.04) would be 6.0796.

We're not finished, because that is just the tax.

Add them together, 151.99+6.0796 = 158.0696

Round to the nearest cent, so $158.07

The appropriate and equivalent expression is listed below ;

(3 × 4) + (3 × 7) = 3(4 + 7) (5 × 9) - (5 × 6) = 5(9 - 6)(32 + 16) = 48 = 8(4 + 2)4(100 - 3) = 97 × 4 7(60+6) = 66 × 7

(3 × 4) + (3 × 7)

Factorize :

Since 3 is common to both sides :

(3 × 4) + (3 × 7) = 3(4 + 7)

(5 × 9) - (5 × 6)

Factorize :

5 common to both sides :

(5 × 9) - (5 × 6) = 5(9 - 6)

(32 + 16) = 48

A common multiple of both 32 and 16 = 8

(8 × 4) = 32

(8 × 2) = 16

Hence,

(8 × 4) + (8 × 2) = 48

(8 × 4) + (8 × 2)

Factorize :

8(4 + 2)
