The rate of change of function 2 is greater than the rate of change (slope) of function 1 by: B. 2.

Since the line on this graph is perpendicular to the y-axis (horizontal line), we can reasonably and logically deduce that its rate of change (slope) is equal to zero (0) because there is no change in the y-value on the y-axis.

This ultimately implies that, the rate of change (slope) of function 1 (y = 6) with an horizontal line is equal to zero (0).

Next, we would calculate the rate of change (slope) of function 2 i.e y = 2x + 7. Mathematically, the standard form of the equation of a straight line function is given by;

y = mx + c

Where:

By comparing the two (2) equations, we have the following:

y = mx + c  ≡ y = 2x + 7

Therefore, the rate of change (slope) of function 2 is equal to 2.

Now, we can calculate the difference between the rate of change (slope) of function 2 and the rate of change (slope) of function 1 as follows:

Difference = 2 - 0

Difference = 2.

The value of a when the value of 5-a is 20 greater than the vaule of 6a-1 is -2.

Inequalities are created through the connection of two expressions. It should be noted that the expressions in an inequality aren't always equal. Inequalities implies that the expressions are not equal. They are denoted by the symbols ≥ < > ≤.

Since the value of 5-a is 20 greater than the vaule of 6a-1. This will be:

5 - a > 6a - 1 + 20

Collect like terms

-a - 6a > - 1 + 20 - 5

-7a > 14

Divide

a > 14 / -7

a > -2

Therefore, a is greater than -2.

If annual fundraising goal of a is​ $100,000 and so far ​$46,088 has been raised, then they have to raise $53912 to reach the goal

The goal of the annual fund raising = $100000

The raised amount = $46088

The amount of money needed to reach the goal = The goal of the annual fund raising - The raised amount

Here we have to use the subtraction

Substitute the values in the equation

The amount of money needed to reach the goal  = 100000 - 46088

= $53912

Hence, if annual fundraising goal of a is​ $100,000 and so far ​$46,088 has been raised, then they have to raise $53912 to reach the goal

Answer:

(2a + 3b)(2a - b)

Step-by-step explanation:

4a² + 4ab - 3b²

consider the factors of the product of the coefficient of a² and b² which sum to give the coefficient of the ab- term.

product = 4 × - 3 = - 12 and sum = 4

the factors are + 6 and - 2

use these factors to split the ab- term

= 4a² + 6ab - 2ab - 3b² ( factor the first/second and third/fourth terms )

= 2a(2a + 3b) - b(2a + 3b) ← factor out (2a + 3b) from each term

= (2a + 3b)(2a - b)

Answer:

x = 1

y = 7

Step-by-step explanation:

y = -x + 8

-y= -2x - 5 (Switch the signs of y = 2x + 5)

0= - 3x + 3 (Subtract both equations)

3x = 3 (Add 3x on both sides)

x = 1 (Divide by 3 on both sides)

y = -1 + 8 (Plug x as 1 in the equation y = -x + 8)

y = 7 (Simplify)

Leading to the answer

x = 1

The cost of each CD is $21 and the cost of each cassette tape is $11.

According to the question,

We have the following information:

Todd purchased two CDs and three cassette tapes for $75. Paulena went to the same music store and purchased one CD and five cassette tapes for $76.

Now, let's take the cost of each CD to be $x and the cost of each cassette tape to be $y.

So, we have the following expressions:

2x+3y = 75 ..(1)

x+5y = 76

x = 76-5y ..(2)

Putting the value of x in equation 1:

2(76-5y)+3y = 75

152-10y+3y = 75

152-7y = 75

Subtracting 152 from both sides:

-7y = 75-152

-7y = -77

y = 77/7

y = $11

Putting this value in equation 2:

x = 76-5y

x = 76-5*11

x = 76-55

x = $21

Hence, the cost of each CD is $21 and the cost of each cassette tape is $11.

Explanation:

Both points have the same x coordinate, which immediately tells us both points are on the same vertical line.

All vertical lines have an undefined slope. This is because when it comes to rise/run, the "run" is zero.  Dividing by zero is not allowed.

Check out the steps below.

[tex](x_1,y_1) = (-10,9) \text{ and } (x_2,y_2) = (-10,18)\\\\m = \text{slope} = \frac{\text{rise}}{\text{run}} = \frac{\text{change in y}}{\text{change in x}}\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{18 - 9}{-10 - (-10)}\\\\m = \frac{18 - 9}{-10 + 10}\\\\m = \frac{9}{0}\\\\m = \text{UND}\\\\[/tex]

Answer:

Step-by-step explanation:

Step-by-step explanation:

when we give a function an actual value as argument, we are using the variable(s) in the functional definition as intended : as placeholders for actual values.

so, we only need to replace any occurrence of the variable by the actual value and calculate.

a.

zero items are produced means x = 0.

C(0) = 10×0 + 900 = $900

fixed cost = $900

b.

making 25 items means x = 25.

C(25) = 10×25 + 900 = 250 + 900 = $1,150

c.

the domain is the interval or set of all valid values for x.

the range is the interval or set of all valid values for y (the functional result).

now, the maximum cost allowed is $1900.

how many items are that ?

1900 = 10x + 900

1000 = 10x

x = 100

so, the domain is

0 <= x <= 100

the range is

$900 <= y <= $1900

Step-by-step explanation:

The answer is tom will give 440 cards to Bala, using arithmetic operation.

What is the arithmetic operation?

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or more quantities. Included in them is the study of numbers, especially the order of operations, which is important for all other areas of mathematics, including algebra, data management, and geometry. The rules of arithmetic operations are required in order to answer the problem.

The total number of cards is 780+240 = 1020.

If in the end Bala will have twice as many cards as Tom then I would divide the 1020 by 3 which equals 340.

So Bala will have 2*340 = 680 cards

Tom will have 340 cards.

Now Bala will need (680-240) = 440 more cards.

Hence Tom will give 440 cards to Bala.

The solution to the equation as written is y = -96/161.

The term linear equation has to do with an equation in which the highest power of the variable is 1. In this case, we have been given a word problem and we would have to convert it to equation.

The equation is now to be written as;

5y + 7/3y = 5/8y - 4

Collect like terms and apply BODMAS;

5y + 7/3y  - 5/8y = -4

22y/3 - 5/8y = -4

161y/24  = -4

24(-4) = 161y
