Answer:

If two quantities x and y are related by y = f(x), the derivative f'(xo) represents the rate of change of y with respect to x at the point xo. It is measured in (units of y)/(units of x). A positive rate of change is sometimes called a rate of increase.

Answer:

C. S=18.25+25t

Step-by-step explanation:

i looked it up on google

Step-by-step explanation:

Hey there!

By looking through figure, l and m are parallel lines and a transversal line passes through the lines.

Now,

7x + 12° = 12x - 28°( alternate angles are equal)

12°+28° = 12x - 7x

40° = 5x

[tex]x = \frac{40}{5} [/tex]

Therefore, x = 8°

Now,

12x - 28° + 9y - 77 = 180° ( being linear pair)

12×8° - 28° + 9y -77° = 180°

96° - 28° + 9y - 77° = 180°

-9 + 9y = 180°

9y = 180° + 9°

y = 189°/9

Therefore, y = 21°

Therefore, X = 8° and y= 21° .

The mean difference in the game scores over six games is 2.5

The mean difference measures the absolute difference between the mean value in two different groups.

Given is a basketball team which played six games such that in those games, the team won by 8 points, lost by 11, won by 7, won by 11, lost by 4, and won by 13 respectively.

The mean difference of the given data can be calculated using the following formula -

Mean Difference = (∑W / n) - (∑L / n)

Where -

(∑W / n) is the mean of games won.

and

(∑L / n) is the mean of games lost.

(∑W / n) = (8 + 7 + 11 + 13)/4 = 9.75

and

(∑L / n) = (11 + 4)/2 = 15/2 = 7.5

Mean difference =  (∑W / n) - (∑L / n) = 9.75 - 7.5 = 2.5

Therefore, the mean difference in the game scores over six games is 2.5

Sum of all angles in a triangle = 180°

Which means :-

∠1 + ∠2 + ∠3 = 180°

[tex]2x + x + x + 8 = 180°[/tex]

[tex]4x + 8 = 180°[/tex]

[tex]4x = 180 - 8[/tex]

[tex]4x = 172[/tex]

[tex]x = \frac{172}{4} [/tex]

[tex]x = 43[/tex]

Angle 1 :-

Answer:

y=9x-17; x=17/9 or x=1 8/9 or x=1.8

y=x+23; x= -23

Step-by-step explanation:

y=9x-17

0=9x-17 (Move variables to the left-hand side and change its sign)

-9x=-17 (Divide both sides of the equation by -9)

x=17/9, x=1 8/9, or x=1.8

y=x+23

0=x+23 (To find x-intercept/zero, substitute y=0)

-x=23 (Move variable to the left-hand side and change its sign)

x= -23 (Change the signs on both sides of the equation)

x= -23

Answer:

x = 5

y = 28

the expressions both equal y so they are equal to each other.  so you right the equation as

9x - 17 = x + 23

then you subtract x from both sides

and then add 17 to both sides

the final step is to divide 8 on both sides and that gives you the answer x = 5. then you plug that back into the problem so...

y = 5 +23

so y = 28.

Answer:the domain is all real numbers it also like the x value and the range is all y value

Step-by-step explanation:

Answer:

The domain is the set of values of "x" for which the function has meaning.

Based on my knowledge x can be any real number except for zero.

The range of f(x) is the same as finding all that y could be.

The range of f(x) is all the y values where there is a number x with y = f(x).

Answer:

$36

Step-by-step explanation:

orig price = $40

discount=10%

40*10/100= 400/100 = 4

$40-4= $36

Answer:

$4

Step-by-step explanation:

x percent = x/100

10 percent = 10/100 = 0.10

10% of $40 = 0.10*40 = 4

You save $4

The old price is $40 and changes to $36 after the discount is applied. This is ignoring any taxes or other surcharges

Answer:

its 3.05

Step-by-step explanation:

The coordinates of A will be at (-10, -5) when the transformation (x,y) → (x + 10, y + 5) is  performed on point A.

Given the coordinate of the resulting image after the transformation is A'(0, 0). We need to get the coordinate of the original image A.

Since the transformation (x,y) → (x + 10, y + 5) is performed on A.

A = (0 - 10, 0 - 5)

If we are going from the pre-image to the image, we will translate to the left and downwards

A = (-10, -5)

Hence the coordinates of A will be at (-10, -5)

Answer:

$18

Step-by-step explanation:

we proceed by first solving for the unit cost of a sheet

then calculate the cost for any number of sheet

We are told that a builder could buy 6 sheets for the cost of $9

this means that one sheet would cost 9/6= $1.5

Now the builder buys 12 sheets

therefore the cost of 12 sheets will be

12*1.5= $18
