Answer:

y = -6x/12 + 9/12 trust me bro I'm good at this

Answer:

[tex]y=-\frac{x}{2}[/tex] + [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

6x + 12y=9

Subtract 6x from both sides.

12y=9-6x

Divide both sides by 12.

[tex]\frac{12y}{12}[/tex]=[tex]\frac{9-6x}{12}[/tex]

Dividing by 12 undoes the multiplication

[tex]y=\frac{9-6x}{12}[/tex]

Divide 9 - 6x by 12

[tex]y=-\frac{x}{2}[/tex] + [tex]\frac{3}{4}[/tex]

The length of a rectangle is 2 more than twice the width. If the perimeter of the rectangle
is 34 inches, what is the area of the rectangle?

Answers

Answer:

Area = WxL=60 square inches

W = 5 inches

L = 12 inches

Step-by-step explanation:

Note, some teachers take points off if you don't include units!!

L = 2W+2

W = W

34 = 2L + 2W (perimeter)

34 = 2(2W+2) +2W solve for width

34 = 4W+4+2W = 6W+4

30 = 6W, so W=5

L = 2(5) +2 = 12

A pair of jeans is on sale for 25% off the original price. Which expression represents the sale
price? If the original price of the jeans is $40, evaluate the expression to find the sale price.
O s=p-0.25p; $30
O s= p - 25; 515
O s = p -0.25p; 510
O s=p-0.25: $39.75

Answers

Answer:

$30

Step-by-step explanation:

If it's 25% off, then to find the sale price we just need to subtract 25% of the original price from the original price.

Original price is 40 so we do 40 - (40 * 0.25) = 30

Erica bought a pencil, a rubber and a ruler for £1. Fritz bought three pens for 75p. Geraldine bought two rubbers and a pen for 45p. Horace bought a pencil, a ruler and a pen.

Answers

Answer:

Okay so, one pen equals to 25p, one rubber equals to 10p, and Erica bought a pencil, a rubber, and a ruler for 1 pound, which means 25p+10p equals to 35p, and 100-35= 65p, so one ruler costs 65p, so Horace bought a pencil, a ruler and a pen, we know one pencil equals 25p, a ruler costs 65p, and a pen also equals 25p, so 25+65+25 = 115, so 1pound 15 p

What are Linear Equations?

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Linear equations may include one or more variables.

Given is a graph of the line.

So the equation must be linear.

The slope intercept form of a line is,

y = mx + c, where m is the slope and c is the y intercept.

The given graph has a negative slope since the graph is decreasing.

That is, the value of y is decreasing with an increase in the value of x.

m is negative.

Find the equations of line in options with negative slope.

Possible options are A and C.

A : y = -2x + 5

C : 2x + y = 4 ⇒ y = -2x + 4

Hence the possible options are A or C.

Please Explain the Answer to me!

Answers

Answer:  ? = 0.14

Step-by-step explanation:

So you need to find the value that fits the question mark. This means you have to get it by itself.

To start you subtract 0.4 from 0.546, which equals .146. Then you subtract 0.006 from 0.146 to get 0.14

What it looks like mathematically :

0.546 = 0.4 + ? + 0.006  

0.146= ? + 0.006  

0.14=?

How do you convert 0.580 (80repeating) as a fraction?

Answers

Answer:

58/100

Step-by-step explanation:

9514 1404 393

Answer:

  115/198

Step-by-step explanation:

The repeat is 2 digits, so you can multiply the number by 10 to that power.

  x = 0.58080...(2-digit repeat)

  100x = 58.08080...(2-digit repeat)

Then subtract the original number.

  100x -x = 99x = 58.08080... -0.58080... = 57.5

Now, divide by the coefficient of x.

  x = 57.5/99 = 115/198

This fraction cannot be reduced, so is the fraction you're looking for.

  0.580...(2-digit repeat) = 115/198

_____

Additional comment

The number of 9s in the denominator is the number of repeating digits. If the repeat started at the decimal point, the fraction would be those two repeating digits divided by two 9s (99).

Your number can be considered to be ...

  0.58080...(2-digit repeat) = 0.5 + 0.0808...(2-digit repeat)

This will be ...

  0.58080... = 1/2 + 8/99 = 99/198 +16/198 = 115/198

What do u need help with?

Residents of the town of Maple Grove who are connected to the municipal water supply are billed a fixed amount monthly plus a charge for each cubic foot of water used. A household using 1900 cubic feet was billed $156, while one using 2600 cubic feet was billed $184. (a) What is the charge per cubic foot? dollars per cubic foot (b) Write an equation for the total cost, c, of a resident's water, , as a function of cubic feet of water used. c(w) = dollars c) How many cubic feet of water used would lead to a bill of $216? cubic feet

Answers

9514 1404 393

Answer:

$0.04 per cubic footc(w) = 0.04w +803400 cubic feet

Step-by-step explanation:

(a, b) We are given two pairs of values:

 (w, c) = (1900, 156) and (2600, 184)

so we can write the equation of the relationship using the 2-point form of the equation of a line.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  c = (184 -156)/(2600 -1900)(w -1900) +156 . . . . . substitute given points

  c = 28/700(w -1900) +156

  c(w) = 0.04w +80

The charge per cubic foot is $0.04.

__

(c) For a bill of $216, the amount of water used is ...

  216 = 0.04w +80

  136 = 0.04w

  3400 = w

Use of 3400 cubic feet of water would lead to a bill of $216.

E is the midpoint of DF, DE = 3x + 4 and EF = 5x - 2. Find DE, EF, and DF.

Answers

Since E is the midpoint of DF, DE and EF are two halves of DF. First, let's write down what we know.

DE = 3x + 4

EF = 5x - 2

DE = EF

DE + EF = DF

Now, let's plug our values for DE and EF into our first expression.

3x + 4 = 5x -2

Add 2 to both sides and subtract 3x from both sides.

6 = 2x

Divide both sides by 2

3 = x

Let's plug 3 in for x into DE.

DE = 3x + 4 = 3(3) + 4 = 9 + 4 = 13

DE = EF = 13

We can plug 13 in for DE and EF to get DF

DF = DE + EF = 13 + 13 = 26
