the answer is option B

[tex] {f}^{ - 1} ( \frac{1}{2} x - \frac{3}{2} )[/tex]

The obtained coordinate points to plot the graph are matching with graph A. Therefore, option A is the correct answer.

Given that, a company charges a delivery fee of $50 to deliver plotting soil and each cubic yard of plotting soil costs $50.

In mathematics, and more specifically in graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense "related".

Let the total cost be y and the number of cubic yards be x.

Now, the equation to represent the given situation is y = 50+50x

By substituting x = 0, 1, 2, 3, 4, 5,....we get

y = 50+50(0) = 50

y = 50+50(1) = 100

y = 50+50(2) = 150

y = 50+50(3) = 200

y = 50+50(4) = 250

So, the coordinates to plot the graph are (0, 50), (1, 100), (2, 150), (3, 200) and (4, 250) and so on.

The obtained coordinate points to plot the graph are matching with graph A. Therefore, option A is the correct answer.

Answer:

I believe it is answer b.

Step-by-step explanation:

You multiply 4x and - 7 by 1/5 which gives you 4/5x and 1 2/5. You add 4/5x and 2/5x as they are like terms and get 1 1/5x. The equation then becomes 1 1/5 - 1 2/5

Answer:

3y = -2x + 24

y = -2/3x + 8

Step-by-step explanation:

Answer:

The slope-intercept form is y=mx+b y = m x + b

Step-by-step explanation:

where m m is the slope and b b is the y-intercept. Subtract 2x 2 x from both sides of the equation. Divide each term by 3 3 and simplify. Divide each term in 3y=24−2x 3 y = 24 - 2 x by 3 3 .

Answer:

f(x) = x³ + 19x² + x + 19

Step-by-step explanation:

Zeros: -19 , -i, complex conjugate root: +i

Function: (x+19)(x+i)(x-i) = 0

(x + 19) (x² - i²) = (x + 19) ( x² + 1) = x³ + 19x² + x + 19

check: when x = 1

f(1) = 1 + 19 + 1 +19 = 40

Answer:

200

Step-by-step explanation:

You can simply just graph it and see where the points intersect, or you can do it algebraically.

0.45x+29.99=0.40x+39.99 subtract 29.99 both sides

0.45x=0.40x+10.00 subtract .40x both sides

0.05x=10.00 divide both sides by 0.05

x=200

Answer:

C.  Yes, there is an x-value that is exactly zero. This is true because zero is our starting point in our profits. The x and y value would be (0,0) as we have just begun to produce energy units. Once the graph starts to increase, we cannot have a point at exactly zero, unless the profits have a dramatic drop to the x value of 0. This would then be (0, at a number of diminishing returns)

Answer3:3

Step-by-step explanation:

Answer: I guessed the first time but got it right the second time

The derivative at x = 3 does not exist.

To see why, recall the definition of absolute value:

[tex]|x| = \begin{cases}x&\text{if }x\ge0\\-x&\text{if }x<0\end{cases}[/tex]

If x - 3 ≥ 0, then

2 + |x - 3| = 2 + (x - 3) = x - 1

and the derivative of this piece is 1 for all x > 3.

If x - 3 < 0, then

2 + |x - 3| = 2 - (x - 3) = 5 - x

and its derivative is -1 for all x < 3.

The derivatives to either side of x = 3 are not the same, so f '(x) is not continuous and indeed does not take on any value at this point.

Answer: 6.5 and 6

Step-by-step explanation:

Answer:

$2.57

Step-by-step explanation:

Create an equation.

7x + 3 = 21

Subtract 3 from both sides of the equation.

7x = 18

Divide 7 from both sides to find x.

18/7 = x,

x = 2.57
