Add: (-15xz-4xy)+(20xy-9yz-16xz)

Answer: 6

Step-by-step explanation: To evaluate this problem, the first thing

we want to do is plug in the appropriate values for a, b, and c.

When we do that, we get \(\frac{3(4)}{4(3) - (10)}\).

A good rule of thumb for problems that involve division bars is to simplify what's above the division bar as much as you can and what's below the division bar as much as you can before you do your dividing.

So up top, we simplify 3(4) to get 12.

Down below, we want to multiply before we subtract.

So 4(3) is 12 and we have 12 - 10 which is 2.

So we have 12 / 2 which simplifies to 6.

Answer:

Perimeter:\(4x+10\) feet
Area:\(x^{2}+5x+6\) feet

Step-by-step explanation:

The perimeter is equal to 2*width +2*length. The width is x+2 and the length is x+3, therefore the perimeter is equal to 2x+4+2x+6 which equals 4x+10.
The area is equal to width*length
(x+3)(x+2)=\(x^{2}+2x+3x+6=x^{2}+5x+6\)

The company's expectation is $486.26.

Step-by-step explanation:

The school club made $298.08 by selling the balloons.

Profit is calculated as total revenue less total expenses.

Given that, a school club sold 143 balloons for $3.50 each. They bought 150 balloons for $1.29 each, plus $8.92 for shipping.

Cost of balloons when they brought them = 1.29*150 = $193.5

Total cost = $193.5 + (shipping price) = $193.5 + $8.92

Total cost = $202.42

Cost at which they sold the balloons = 143*$3.50 = $500.5

Therefore, their total profit = $500.5 - $202.42 = $298.08

Hence, The school club made $298.08 by selling the balloons

F and G are inverse if both of them satisfy the condition h(x)=x. f(g(x))=g(f(x))=x, as we discovered. The argument f(x) and g(x) are inverse functions is thus established.

If f (x) and g (x) are inverse functions, it can be determined using one of two ways. For more information, see the explanation.

Explanation:

Instance 1

Inverse functions of both functions can be found using the first method.

Example.

Inverse of f (x) = x + 7 is what we're looking for.

We attempt to determine x using the equation y = x + 7.

y = x + 7

Inferring that g (x) is the inverse of f (x) from the fact that x = y 7

Finding g (x inverse )'s is now necessary.

g( x ) = x − 7

y = x − 7

x = y + 7

As a result, we discovered that f (x) is the inverse function of g (x).

f and g are equal if g is inverse of f and vice versa.

The second approach entails locating the compound functions f ( g ( x ) ) and g ( f ( x ) ). In this case, f and g are inverse if they are both h (x ) = x.

Example:

f ( g ( x ) =  [ x − 7 ] + 7

G ( x ) placed as x is the expression in brackets.

f ( g ( x ) ) = x − 7  + 7 = x

g (f ( x ) =  [ x + 7 ] − 7

f ( x ) inserted as x is the expression in brackets.

g ( f ( x ) ) = x + 7 − 7 = x

The equation f ( g ( x ) ) = g ( f ( x ) ) = x was what we discovered. The argument f (x) and g (x) are inverse functions is thus established.

Leanne will earn if she sells: $140 if she sells 10 subscriptions and $210 if she sells 15 subscriptions.

We are given:

Leanne earns $14 for every subscription she sells.

We need to find earnings of Leanne for the sale of 10 subscriptions and 15 subscriptions.

We will solve the given problem using the unitary method.

Since for 1 subscription Leanne sells, she earns $14.

So, for 10 subscriptions Leanne sells, she will earn $14 * 10 = $140.

So, for 15 subscriptions Leanne sells, she will earn $14 * 15 = $210.

So, for 10 subscriptions Leanne earns $140 and for 15 subscriptions Leanne earns $210.

The mean monthly rainfall, Rounded to the nearest thousandth, is 2.520 inches.

To determine the mean monthly rainfall, we need to calculate the average of the rainfall values provided in the table. Here is the table:

| Month | Rainfall (in inches) |

|-------|----------------|

| January   | 2.3                

| February  | 1.7                

| March     | 3.2                

| April     | 2.9                

| May       | 2.5                

To find the mean monthly rainfall, we add up the rainfall values for each month and divide the sum by the total number of months. In this case, we have five months:

Mean Monthly Rainfall = (2.3 + 1.7 + 3.2 + 2.9 + 2.5) / 5

Calculating the sum of the rainfall values:

Mean Monthly Rainfall = 12.6 / 5

Dividing the sum by the number of months:

Mean Monthly Rainfall = 2.52

Rounded the result to the nearest thousandth, the mean monthly rainfall is approximately 2.520 inches.

Therefore, the mean monthly rainfall, rounded to the nearest thousandth, is 2.520 inches.

Step-by-step explanation:

Answer:

y=(-1/9)x-(10/3)

Step-by-step explanation:

Since the line is perpendicular to y=9x-5, the slope of that line would be the opposite of the reciprocal of the original slope value. In this case, the slope of the line would be -1/9. So we have y=(-1/9)x+? Since we know a point, (-3, -3), we can input this back into our original equation and we have: -3=(1/3)+? We simplify and we have ?=-10/3. Therefore the final equation of the line that is perpendicular to that line and passes through the point (-3,-3) is y=(-1/9)x-(10/3).  

The answers of the following part are:

a) 22

b) -76

c) -13

For solving this particular sum we need to know the about functions Function is generaaly defined as a set of inputs having one output each. every function as a domain and a co-domain or range. A function is generally denoted by f(x) where x is the variable and it is also the input.The general representation of function is y = f(x).

In the given sum we will just put the values in place of x and will find the answer

The given equation is f(x)=-13+7x

a) Here it is given f(5)  so we will put 5 in all places of x

Substituting the value x as 5 we will get :

f(5) = -13+7*5

= -13+35

=22

the value f(5) will be 22

b) In this part of the vaule of x is given as -9

Substituting the value of x as -9 we get

f(-9)=-13+7*(-9)

= -13-63

= -76

the valur of f(-9) is -76

c) here the value of x is given as 0

Substituting the value of x as 0

f(0)= -13+7*0

= -13+0

The expected number of times the sequence "proof" appears in a randomly generated string of n = 1,000,004 letters can be calculated using the formula:

expected_occurrences = (n - 4) / 26^4

The average velocity for the time period beginning when t=3 and lasting for

1) 0.01 s: -9051.12 ft/sec

2) 0.005 s: -18051.06 ft/sec

3) 0.002 s: -45051.1 ft/sec

4) 0.001 s: -90051  ft/sec

Here, a ball is thrown with initial velocity of 46 ft/s.

The height of the ball in feet after t seconds is given by an equation,

 y = 21t - 12t²

Let us assume that P represents the average velocity.

The average velocity is given by formula,

P = [y(t₂) - y(t₁)]/[t₂ - t₁]

i) the average velocity for the time period beginning when t=3 and lasting  0.01 s

Here, t₂ = 3.01 s and  t₁ = 3 s

y(t₂) =  21(3.01) - 12(3.01)²

      = -45.5112

y(t₁) =  21(3) - 12(3)²

      = 45

y(t₂) - y(t₁) = -45.5112 - 45

                = -90.5112

So, P = -90.5112 / (0.01)

     P = -9051.12 ft/sec

ii) the average velocity for the time period beginning when t=3 and lasting  0.005 s

Here, t₂ = 3.005 s and  t₁ = 3 s

y(t₂) - y(t₁) = -45.5112 - 45

                = -90.2553

So, P = -90.2553 / (0.005)

     P = -18051.06 ft/sec

iii) the average velocity for the time period beginning when t=3 and lasting  0.002 s

Here, t₂ = 3.002 s and  t₁ = 3 s

y(t₂) - y(t₁) = -45.1021 - 45

                = -90.1021

So, P = -90.1021 / (0.002)

     P = -45051.1 ft/sec

iv) the average velocity for the time period beginning when t=3 and lasting  0.001 s

Here, t₂ = 3.001 s and  t₁ = 3 s

y(t₂) - y(t₁) = -45.051 - 45

                = -90.051

So, P = -90.051 / (0.001)

     P = -90051 ft/sec

"A chemist is using 386 millilitres of a solution of acid and water."

This sentence implies that the solution only contains acid and water.

Now, we are told:

"12.4% of the solution is acid."

What is 12.4% percent though, as a decimal?

Well, 12.0% is actually equal to 0.12 as a decimal. 0.4% is actually 1/2 of 1%, which in turn is 1/2 of 0.010 which is 0.005 as a decimal.

So, we now know that 12.4% is actually equal to 0.124 as a decimal.

Let's multiply 0.124 by 386 to get our answer.

0.124 x 386 = 47.86 (rounded to the nearest tenth)

There are 47.86 millilitres (to the nearest tenth) of acid in the solution.
