Answer:

2/3 card per hour

Step-by-step explanation:

The correct calculation is given below

The number of cards she can make per hour is :

12 hours = 8 cards

1 hour = x cards

Cross Multiply

12 hours × x cards = 8 cards × 1 hour

x cards = 8 cards × 1 hour/12 hours

x cards = 2/3 card

She can make 2/3 card per hour

Step-by-step explanation:

Answer:

Yes

Step-by-step explanation:

You are using the x values once, so it will pass the vertical line test.

{(3,4), (5,0), (2,4), (-5,-5)} the relation is a function.

A relation is a function if it has only One y-value for each x-value.

The relation is {(3,4), (5,0), (2,4), (-5,-5)}

Relation on a set may, or may not, hold between two given set members.

Three comma four comma five comma zero two comma four comma minus five comma minus five.

{(3,4), (5,0), (2,4), (-5,-5)} the relation is a function, because in (x,y) the x terms are not repeated.

For every y value there is a unique x value.

Hence, {(3,4), (5,0), (2,4), (-5,-5)} the relation is a function.

Answer:

91%

Step-by-step explanation:

The first step is to calculate the increase

= 1635-858

= 777

Therefore the percent increase can be calculated as follows

= 777/858 × 100

= 0.905× 100

= 90.5 %

= 91%

Hence the percentage increase is 91%

Answer:

the amount that he makes last week and in the year 2011 is $770 and $40,040 respectively

Step-by-step explanation:

The computation of the amount that he makes last week and in the year 2011 is as follows:

= Sale value of the stocks × earning percentage × number of weeks in a year

= $7,000 × 11% × 52 weeks

= $40,040

hence, the amount that he makes last week and in the year 2011 is $770 and $40,040 respectively

Step-by-step explanation:

Answers:

==============================================

Explanation:

For problems 9 through 12, we'll use the same set of steps. Recall that any parallelogram has the property that the adjacent angles are supplementary. This means close by angles add to 180. Each of the four diagrams show pairs of adjacent angles.

------------------

In problem 9, we have the following steps

(79x-1) + (102) = 180

79x + 101 = 180

79x = 180-101

79x = 79

x = 79/79

x = 1

------------------

Problem 10 is the same idea

(85) + (30x+5) = 180

30x+90 = 180

30x = 180-90

30x = 90

x = 90/30

x = 3

------------------

Problem 11

(55)+(9x+17) = 180

9x+72 = 180

9x = 180-72

9x = 108

x = 108/9

x = 12

------------------

Problem 12

(3x+12)+(132) = 180

3x+144 = 180

3x = 180-144

3x = 36

x = 36/3

x = 12

Answer:

9. X = 1

10. X = 3

11. X = 12

12. X = 12

Step-by-step explanation:

9.

1) 79x - 1 + 102 = 180

2) 79x + 101 = 180

3) Subtract 101 from both sides

4) 79x = 79

5) x = 1

10.

1) 85 + 30x + 5 = 180

2) 30x + 90 = 180

3) Subtract 90 from both sides

4) 30x = 90

5) x = 3

11.

1) 55 + 9x + 17 = 180

2) 9x + 72 = 180

3) Subtract 72 from both sides

3) 9x = 108

4) X = 12

12.

1) 3x + 12 + 132  = 180

2) 3x + 144 = 180

3) Subtract 144 from both sides

4) 3x = 36

5) x = 12

Answer:

I can find all the x-values in the domain of the function f(x)=4:

Domain = (−∞, ∞), {x | x∈R}

Here’s the range if you need it:

Range: {4}

Hope this helps! :)

The answer is Range: {4} or,  x is a member of the real numbers and that it can be anything from negative infinity to positive infinity.

A number is a mathematical object used to count, measure, and label. The original examples are the natural numbers 1, 2, 3, 4, and so forth. Numbers can be represented in language with number words.

Here, we have,

f (x) =4

now,

we can find all the x-values in the domain of the function f(x)=4:

Domain = (−∞, ∞), {x | x∈R}

Here’s the range if you need it:

Range: {4}

There are x’s in the equation.

It’s actually all numbers are x’s because anything you put into the function f(x)=4, y will always equal 4.

So the value of x in f(x)=4 is all numbers.

To be more specific, all real numbers.

That’s why I put (−∞, ∞), {x | x∈R} because x is a member of the real numbers and that it can be anything from negative infinity to positive infinity.

Step-by-step explanation:

Answer:

16 p plus 32 q equals 1280

16p + 32q = 1,280

Step-by-step explanation:

A pint = 16 ounces

A quart = 32 ounces

p = number of pints he canned

q = number of quarts he canned

if Chin canned a total of 1,280 ounces?

Total ounces canned = 1,280

Equation:

p × 16 ounces + q × 32 ounces = 1,280

16p + 32q = 1,280

The options:

1280 plus 16 p equals 32 q

1,280 + 16p = 32q

1280 plus 32 q equals 16 p

1,280 + 32q = 16p

32 q minus 16 p equals 1280

32q - 16p = 1,280

16 p plus 32 q equals 1280

16p + 32q = 1,280

The correct answer is

16 p plus 32 q equals 1280

16p + 32q = 1,280

Answer:

16p+32q=1280

Step-by-step explanation:

The input(x) does not repeat

Answer: -3

Step-by-step explanation: just multiply

The best estimate of the average rate of change for the function graphed over the interval 1 ≤ x ≤ 3 is 3.

Average rate of change of a function is defined as the rate at which the value of the function is changing with respect to the change in the input values.

The interval given is 1 ≤ x ≤ 3.

The graph of the function is given below.

It can be clearly seen that,

The y value corresponding to x = 1 is y = f(1) = 2.

So one point on the graph is (1, 2).

The y value corresponding to x = 3 is y = f(3) = 8.

So the other point on the graph is (3, 8).

Average rate of change over 1 ≤ x ≤ 3 = [f(3) - f(1)] / [3 - 1]

                                                               = [8 - 2] / [2]

                                                               = 6/2

                                                               = 3

Hence the best estimate for the average rate of change of function over the interval 1 ≤ x ≤ 3 is 3.
