Michael bought a $12.99 CD and 3 packs of gum. Andie bought a different CD for $8.99 and 6 packs of
gum. Each of them spent the exact same amount. Which equation below could be used to find g, the
cost of one pack of gum?
A 12.99+ g = 8.99 + 9
B 12.99 + 3g = 8.99 + 69
C 12.99 + 8.99 = 3g + 69
D 12.99 + 69 F 8.99 +39

[tex]f(x) = \frac{10}{9}x + 11 \\ [/tex]

So :

[tex]y = \frac{10}{9}x + 11 \\ [/tex]

Subtract the sides of the equation minus 11

[tex]y - 11 = \frac{10}{9}x \\ [/tex]

Multiply the sides of the equation by 9

[tex]9(y - 11) = 10x[/tex]

[tex]9y - 99 = 10x[/tex]

Divided the sides of the equation by 10

[tex] \frac{9y - 99}{10} = x \\ [/tex]

So :

[tex] {f}^{ - 1}(x) = \frac{9x - 99}{10} \\ [/tex]

Answer:

Step-by-step explanation:

I have some sympathy for the way the questions have been set up and numbered.

The givens are that the two lines that look like they are perpendicular, are perpendicular.

<JKP = 67                    Given

<PKL = 180 - 67          < PKL is supplementary to <JKP

<PKL = 113

<PKM = 113 - 90 = 23

Here's what you want to know. <NKO = PKM because they are vertically opposite angles.

Therefore NKO = 23 degrees.

JL is perpendicular to MN, then

m ∠NKO= 23°

Given :

JL is perpendicular to MN and the m∠JKP= 67°

we need to find out m∠NKO

we know that JL is perpendicular to MN.  so, <JKN makes an right angle .

m ∠JKN = 90°

PO is a straight line . It makes an angle 180 degree

m ∠JKP +m ∠JKN +m ∠NKO =180

[tex]67+90+m<NKO=180\\m<NKO=180-90-67\\m<NKO=23[/tex]

m ∠NKO= 23°

Answer:

x = 7 1/3

Step-by-step explanation:

First, add 1/2 and 6

1/2 + 12/2 = 13/2 = 6 1/2

Our equation now:

13/2 over 3 - x - 3 over 2 = 0

Next, divide 13/2 by 3

13/2 divided by 3 = 13/6

Our equation now:

13/6 over 3 - (x - 3) over 2 = 0

Now, find common denominators and simplify

13/6 - ((x - 3) times 3) over 6 = 0

22 - 3x over 6 = 0

Multiply by six on both sides

22 - 3x = 0

Subtract 22 from both sides

-3x = -22

Divide by -1

3x = 22

Divide both sides of the equation by 3

x = 22/3

x = 7 1/3

Answer:

there's no expressions, just plus and minus signs-

Step-by-step explanation:

Answer:

The true statemens are:

All function have (at least) a dependent variable. That is why you can write y = f(x), x is the independent variable, while y depends on x values, so y is the independent variable.

All function have and independent variable (explained above).

A horizontal line is an example of a funcitional relationship (because given a value of x, you can always tell the value of y)

The other statements are false:

The range of a function includes its domain is false.

Domain are the values that x can take and the range are the values that the function (y) can take. One is not included in the other.

A vertical  line is an example of a functional relationship is false, because you can not tell the value of y for any value of x.

Each output value of a function can correspond to only one input value is false.  An output can be generated by more than one value of x. The horizontal line is an example of that: the same value of y (output) corresponde to any value of x.

Step-by-step explanation:

Answer:

A: All functions have a dependent variable.

B: All functions have an independent variable.

E: A horizontal line is an example of a functional relationship.

193.95 Canadian dollars

Step-by-step explanation:

Given: Each U.S. Dollar is worth 1.293 Canadian dollars and each Canadian dollar is worth 0.773 U.S. Dollar.

To find: Value of 150 U.S. dollars in terms of Canadian dollars

Value of 1 U.S. dollar = 1.293 Canadian dollars

To find 150 U.S. dollars in terms of Canadian dollars, multiply 150 by 1.293

Value of 150 U.S. dollars in terms of Canadian dollars = 150 × 1.293 = 193.95 Canadian dollars

If you have any questions about the way I solved it, don't hesitate to ask me in the comments below ;)

Step-by-step explanation:

Sum of −8.46 and 5.31 means we need to add −8.46+5.31.

We know that,

|-8.46| > |5.31|

It means we subtract 8.46 - 5.31

At hundredth place, 6-1 = 5

At tenths place, 4-3 = 1

At ones place, 8-5 = 3

It would mean that, 8.46 - 5.31 = 3.15

8.46 has a negative sign. It means that the final answer will have negative sign i.e. −8.46+5.31 = -3.15

Hence, the correct option is (a) " Because |−8.46|>|5.31|, subtract |5.31| from |−8.46| and the sign is negative".

Answer:

Number of hamburgers bought = 4

Number of hotdogs bought = 9

Step-by-step explanation:

Let

Number of hamburgers bought = n

Number of hotdogs bought = n + 5

Hamburgers cost = $6.25

Hotdogs cost = $3.75

Total cost = $58.75

6.25n + 3.75(n + 5) = 58.75

Open parenthesis

6.25n + 3.75n + 18.75 = 58.75

Collect like terms

6.25n + 3.75n = 58.75 - 18.75

10n = 40

Divide both sides by 10

n = 40 / 10

= 4

n = 4

Number of hamburgers bought = n = 4

Number of hotdogs bought = n + 5

= 4 + 5

= 9

Answer:

-2x + y = -3

Step-by-step explanation:

First, distribute the right side:

y+5 = 2x+2

Then, subtract both sides by 2x:

-2x + y + 5 = 2

Lastly, subtract both sides by 5:

-2x + y = -3
