What is the value of x?
A.) х= 21
B.) x= 28
C.) x= 35
D.) x= 37

Answer:

The answer is

[tex] \huge x > - 8[/tex]

Step-by-step explanation:

[tex]5 − (x + 5) > −2(x + 4)[/tex]

First of all expand the terms in the bracket

That's

[tex]5 - x - 5 > - 2x - 8 \\ - x > - 2x - 8[/tex]

Add 2x to both sides

[tex] - x + 2x > 2x - 2x - 8 \\ x > - 8[/tex]

We have the final answer as

[tex]x > - 8 [/tex]

Hope this helps you

Answer:

x > -8

Step-by-step explanation:

5 − (x + 5) > −2(x + 4)

Simplify both sides first:

5 - x - 5 > -2x - 8

-x > -2x -8

Now isolate the variable:

-x > -2x -8

+2x  +2x

x > -8

Answer:

The perimeter of the second(big) square = [tex]\mathbf{4 \times \begin {pmatrix} \dfrac{80-x}{4} \end {pmatrix}}[/tex]

Step-by-step explanation:

From the information given:

The length of the piece of the wire  = 80 cm

When being cut into two pieces;

the length of the first wire = x

Then the length of the second(big) wire will be = 80 - x

However, when each piece is bent to a square shape

The length of one side of the first square = [tex]\dfrac{x}{4}[/tex]

The length of one side of the second(big) square; [tex]\dfrac{80-x}{4}[/tex]

Area of a square = l² ( where l is the length of the sides)

For the first square

A₁ = [tex](\dfrac{x}{4})^2[/tex]

A₁ = [tex]\dfrac{x^2}{16}[/tex]

The area of the second(big) square is:

A₂ = [tex](\dfrac{80-x}{4})^2[/tex]

A₂ = [tex](\dfrac{(80-x)^2}{4})[/tex]

The perimeter of the first square = [tex]4 \times \dfrac{x}{4}[/tex]

The perimeter of the second(big) square = [tex]\mathbf{4 \times \begin {pmatrix} \dfrac{80-x}{4} \end {pmatrix}}[/tex]

Answer:

y = -3x + 8

I've done the steps in the photo

Hope it helps (｡･ω･｡)

Answer:

y = - 3x + 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (8, - 16) and (x₂, y₂ ) = (1, 5)

m = [tex]\frac{5+16}{1-8}[/tex] = [tex]\frac{21}{-7}[/tex] = - 3 , thus

y = - 3x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (1, 5 ) , then

5 = - 3 + c ⇒ c = 5 + 3 = 8

y = - 3x + 8 ← equation of line

Answer:

32 2/3

(40 miles in one hour)

Answer:

The quantity of water in the tank after 15 days is 1610.0 gallons OR 1.61 × 10³ gallons.

Step-by-step explanation:

The amount of water in the tank after 15 days is given by the series

910+(−710)+810+(−610)+⋯+310+(−110)+210

From the series, we can observe that, if water is added for a particular day then water will be drained the following day.

Also, for a day when water is to be added, the quantity to be added will be 100 gallon lesser than the quantity that was last added. Likewise, for a day when water is to be drained, the quantity to be drained will be 100 gallons lesser than the quantity that was last drained.

Hence, we can complete the series thus:

910+(−710)+810+(−610)+710(-510)+610(-410)+510(-310)+410(-210)+310+(−110)+210

To evaluate this, we  get

910-710+810-610+710-510+610-410+510-310+410-210+310-110+210

= 1610.0 gallons

Hence, the quantity of water in the tank after 15 days is 1610 gallons OR 1.61 × 10³ gallons.

Answer:

no solution

Step-by-step explanation:

It's no solution because the first step to do is to subtract 9 from both sides which would give you x=x-18 but now your stuck here because if you subtract x from both sides then you wont have an x so this equation has no solution

Answer:

No solution

Step-by-step explanation:

Answer:

There are two -1s in the expression, so the sign of the positive term will change two times: positive → negative → positive. So, the final expression will be positive.

Answer:

The equation of the line is y = [tex]\frac{4}{3}[/tex] x + 2

Step-by-step explanation:

The form of the equation that passes through two points (x1, y1) and (x2, y2) is y = m x + b, where

Let us solve the question:

∵ The line passes through the points (-3, -2) and (3, 6)

∴ x1 = -3 and x2 = 3

∴ y1 = -2 and y2 = 6

→ Use the rule of m to find it

∵ [tex]m=\frac{6-(-2)}{3-(-3)}=\frac{6+2}{3+3}=\frac{8}{6}[/tex]

→ Simplify it by dividing up and down by 2

∴ m = [tex]\frac{4}{3}[/tex]

→ Substitute its value in the form of the equation above

∴ y = [tex]\frac{4}{3}[/tex] x + b

→ To find b substitute x and y by x1 and y1

∴ -2 = [tex]\frac{4}{3}[/tex] (-3) + b

∴ -2 = -4 + b

→ Add 4 to both sides

∴ -2 + 4 = -4 + 4 + b

∴ 2 = b

→ Substitute it in the form of the equation

∴ y = [tex]\frac{4}{3}[/tex] x + 2

∴ The equation of the line is y = [tex]\frac{4}{3}[/tex] x + 2

Answer:

8x=12 cause y would cancel out and then you just add 2 and 6, and 7 and 5.

15.50 x 20 = $310

31 x 8 = $248

310 + 248 = $558

Answer:

x = 1

Step-by-step explanation:

6x + 6x - 7 = 5

combine like terms

12x - 7 = 5

add 7 to both sides of the equation

12x - 7 + 7 = 5 + 7

12x = 12

divide both sides of the equation by 12

12x/12 = 12/12

x = 1

Answer:

11.7

Step-by-step explanation:

Answer:

11.7 feet

Step-by-step explanation:

Area finds the length times the width (LxW). In other words, area is how long the first side is multiplied by how wide the second side is. If A=LxW, and we know A is 136, then we know that 136=LxW. This alone isn't enough to find L and W. However, we do know that the patio is a square. Squares have equal sides, so L and W will be the same number. Basically, you need to find the number that equals 136 when it's multiplied by itself. X multiplied by X needs to be 136. You can do this easily with a calculator, if you're allowed to have one. just use the square root function on 136, and be sure to round your answer. If you're not allowed to use a calculator, it's a bit more trial-and-error. Try to see what numbers multiplied by themselves get close to 136, and narrow it down from there (ex. if 11 is too little and 12 is too much, the answer is between 11 and 12). You can also look up video tutorials for how to find a square root without a calculator, or use other study platforms. I hope this helps, and feel free to ask me any questions!! :)

Answer:   x-intercept = 7/5 = 1.40000

 y-intercept = -7/4 = -1.75000

Step-by-step explanation: Solve   4y-5x+7  = 0

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  4y-5x+7  = 0 and calculate its properties

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -1.750 and for x=2.000, the value of y is 0.750. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 0.750 - (-1.750) = 2.500 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     =  2.500/2.000 =  1.250
