Answer:

f'(x) = -6/x³

Step-by-step explanation:

We are given;

f(x) = 3/x²

Using quotient rule, we can write as;

f(x) = g(x)/h(x)

To find the derivative, from quotient rule, we can write;

f'(x) = [(h(x)*g'(x)) - (g(x)*h'(x))]/(h(x))²

g'(x) = 0

h'(x) = 2x

Thus;

f'(x) = [(x²*0) - (3*2x)]/(x²)²

f'(x) = -6x/x⁴ = -6/x³

f'(x) = -6/x³

Answer:

20 Input

10 output

Step-by-step explanation:

Here, we want to select the input and output that works

From the diagram, the correct answer is 20 and 10

Let us look at how the rule is followed;

divides input by 2

20/2 = 10 which is the output

Subtract 10 to get output

20-10 = 10

Answer:

m∠NPM = 101

Step-by-step explanation:

Since LM is a straight line, Angle LPM and Angle NPM have to equal 180 degrees (they are supplementary), so we make the equation:

180-79=measure of angle NPM

m∠NPM = 101

Answer:

<NPM = 101°

Step-by-step explanation:

<NPM = 180° - <LPN ( because LPM is a straight line and it should measure 180°)

<NPM = 180° - 79°

<NPM = 101°

Answer:

x (is greater than or equal to) -24

Step-by-step explanation:

x/-6 - 8 (is greater than or equal to) -12

add 8 to both sides

x/-6 (is greater than or equal to) 4

multiply both sides by -6

x (is greater than or equal to) -24

sorry I didnt know where to find the sign so I just wrote is greater than or equal to

Answer:1$ cards = 11 cards 3$ cards= 13

Step-by-step explanation:the first equation is -x-y=-24 and the second is x+3y=50. Solving them as a system will get 2y=26 to y=13 then plug in 13 to the y for -x-y=-24 to get 11. Mr jacobs is hard I know lol. Use elimination by subtraction and keep the first equation as x+y=24 and then flip to negative

Answer:

$25

Step-by-step explanation:

Given that:

Cost of Ashley's dinner in Bloomington = $20

Sales tax = 10%

Tip = 15% on $20

To find:

Total cost of the meal ?

Solution:

Let us find the sales tax first of all.

Sales tax is 10% of the total bill.

Therefore, sales tax = 10% of $20

[tex]\Rightarrow \dfrac{10}{100}\times 20\\\Rightarrow \$2[/tex]

Tip left is 15% of the total bill.

Therefore, tip = 15% of $20

[tex]\Rightarrow \dfrac{15}{100}\times 20\\\Rightarrow \$3[/tex]

Now, total cost of the meal = Food cost + Sales tax + tip

Total cost of the meal = $20 + $2 + $3 = $25

[tex]\large\boxed{\tt x=2}[/tex]

Step-by-step explanation:

[tex]\textsf{We are asked to solve for the value of x.}[/tex]

[tex]\textsf{We are given an equation where x is on both sides of the equation.}[/tex]

[tex]\large\underline{\textsf{Solving;}}[/tex]

[tex]\textsf{Begin solving by adding x to both sides of the equation to cancel out -x on the right}[/tex]

[tex]\textsf{side of the equation. Afterwards, simplify the left side of the equation to evaluate}[/tex]

[tex]\textsf{x.}[/tex]

[tex]\large\underline{\textsf{Evaluating x;}}[/tex]

[tex]\tt -2 + x= -x + 2[/tex]

[tex]\textsf{Remove the -x on the right side by adding x to both sides of the equation.}[/tex]

[tex]\tt -2 + x +\boxed{\tt x} = -x + \boxed{\tt x}+ 2[/tex]

[tex]\tt -2 + 2x = 2[/tex]

[tex]\textsf{Now, we should simplify the left side of the equation as there's only a whole number}[/tex]

[tex]\textsf{on the right side of the equation.}[/tex]

[tex]\textsf{Remove the -2 on the left side of the equation by adding 2 to both sides of the equation.}[/tex]

[tex]\tt -2 + \boxed{\tt 2}+ 2x = 2 + \boxed{\tt 2}[/tex]

[tex]\tt 2x = 4[/tex]

[tex]\textsf{Lastly, divide both sides of the equation by 2 to find the value of x.}[/tex]

[tex]\tt \frac{2x}{2} = \frac{4}{2}[/tex]

[tex]\large\boxed{\tt x=2}[/tex]

Answer:

[tex] \sf \: x = 2[/tex]

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ -2 + x = -x + 2

Then the value of x will be,

→ -2 + x = -x + 2

→ x + x = 2 + 2

→ 2x = 4

→ x = 4 ÷ 2

→ [ x = 2 ]

Hence, the value of x is 2.

Answer:

1. Second Choice

2. Positive

3. Line B

4. Line D

5. Horizontal

Step-by-step explanation:

The y-intercept is the value of b —

[tex]y = mx + b[/tex]

where m = slope and b = y-intercept.

Looking from the graph, the graph passes y-axis at (0,1) which is y-intercept.

Basically (0,a) is y-intercept.

Thus, our y-intercept is (0,1)

The slope is positive. If the slope is negative, it would face opposite.

For zero slope, the graph will become a horizontal line.

An undefined slope is the vertical line graph.

Line B has zero slope. As said, the zero slope will turn the graph into a horizontal line.

Line D has an undefined slope. Read Third Screenshot.

As said, an undefined slope is the vertical line.

[tex]y = - 3[/tex]

This is called Constant Function where the graph is a horizontal line. For a vertical line, it must be x = a (where a is constant)

FYI,

y = a — horizontal

x = a — vertical

Answer:

24.14%

Step-by-step explanation:

Given that,

A team's total salaries is $4,614,244.

The team would like to bring the total down to $3.5 million = $3500000

We need to find the percentage decrease in the team's total salary. The percentage decrease/increase in any value is givenby :

[tex]\%=\dfrac{\text{change in population}}{\text{initial population}}\times 100\\\\=\dfrac{3500000-4,614,244}{4,614,244}\times 100\\\\=24.14\%[/tex]

So, the percentage decrease in the team's total salary is 24.14%.

Answer:

B. Positive slope

Step-by-step explanation:

The line on the graph is positive, as it grows from left to right.

Answer:

Positive Slope

Step-by-step explanation:

The line goes up, which means that it's positive. To be exact the line equation is y = 3x + 1. The slope (3) is positive, which proves that its a positive slope, not negative.

Step-by-step explanation:

Answer:

72:48

Step-by-step explanation:

Answer:

Call the line (d): y = ax + b

(d) intersects the vertical axis at the point where the intersection is 3 ⇒x = 0, y = 3 Instead of (d) we have: b = 3

(d) intersects the horizontal axis at the point where the coordinate is -1 ⇒x = −1, y = 0 Instead of (d) we have: −a + b = 0

Replace into b = 3 into -a + b = 0 we have: −a + 3 = 0⇔a = 3

So the equation for the line is y = 3x + 3
