Answer:

Answer = (2)n+(2)

Step-by-step explanation:

                    first difference = -2

                    Now,   -2 = -2 × (n) + (0)        if      n = 1          

                        or     -2 = -2 × (n) + (-6)      if       n = -2

                        or     -2 =  |-2| ×(n) + 2   ::::  -2 = 2n +2       if      n = -2

D) b/7 + 18 =16

Step-by-step explanation:

Let's solve your equation step-by-step.

b/7+18=16

Step 1: Simplify both sides of the equation.

1/7b+18=16

Step 2: Subtract 18 from both sides.

1/7b+18−18=16−18

1/7b=−2

Step 3: Multiply both sides by 7.

7*(1/7b)=(7)*(−2)

b=−14

Answer:3

Answer:

A negative exponent flips the fraction and turns the exponent positive, and vice versa.

1/121 = 1/1211 = 121-1

As an example, 5-2 = 1/25, and 1/5-2 = 25.

There will be roughly 12,000 bacteria after 12 hours.

The value of the constant k such that the system has infinitely many solutions is; -2.

It follows from the task content that the system of equations given upon observation are multiples.

Hence, by multiplying the second equation by -2; we have;

-4x +6y = 4

-4x +6y = -2k

Hence, for the system to have infinitely many solutions; 4 = -2k.

Ultimately, k = -2 by dividing both sides of the equation above by -2.

The length of time that it cost less to move good across town will be more than 2.36 hours.

From the information, ACME movers charges $59 plus $20 per hour to move household goods across town and Hank movers charges $45 per hour.

Let the number of hours be represented by h.

Therefore, the appropriate equation will be:

59 + 20h = 45h

Collect like terms

45h - 20h = 59

25h = 59

h = 59/25

h = 2.36 hours.

Therefore, the length of time that it cost less to move good across town will be more than 2.36 hours.

The equation solved for 'd' gives  d =  3f - g³/ 4h

The subject of a formula is defined as the variable expressed in terms of the other variables.

It is also the variable that is worked out in a given equation or expression;

Given the equation;

4hd = 3f - g³

To solve for 'd'

Divide both sides by the coefficients of d, we have;

4hd/ 4h =  3f - g³/ 4h

We then have

d =  3f - g³/ 4h

Rounding to an estimate, Sachin will have enough gas to go to both places before he runs out of gas.

An estimate is an equivalent numerical value obtained by rounding off.

The result of an estimate is not an exact value.  The value represents the nearest rounded value.

For instance, 75.9% can be estimated or rounded off to 76%.  32 minutes can be rounded off or approximated to ¹/₂ hour.

Driving distance before getting gas = 110 miles

The distance to his friend's house = 67 miles

The distance to his mom's house = 32 miles

The total distance to be covered on the available gas = 99 miles

Estimated distance to be covered = < 100 miles

Thus, using estimation, Sachin will still have more than 10 miles to drive before he gets gas.

Answer:

It means that the -4 is one of the solutions for this polynomial. In other words, -4 is a point in the x axis of the graph where the function touches said axis.

The value of the polynomial at P(-4) will be 0.

A polynomial in mathematics is an expression made up of coefficients and indeterminates and involves only the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables.

Given that the polynomial function is P(x) = x³ + 11x² + 34x + 24. The value of the function at P(-4) will be calculated as:-

P(x) = x³ + 11x² + 34x + 24

P(-4) = (-4)³ + 11(-4)² + 34(-4) + 24

P(-4) = -64 + 176 - 136 + 24

The number of each type of vehicle sold are :

SUVs : 300

Passenger cars : 270

Number of SUVs were sold more than passenger cars = 30

Total number of cars sold = 540

Let the number of Passenger car sold = x

Then, The number of SUVs sold = x + 30

So, Total number of cars sold = Number of Passenger car sold + Number of SUVs sold

     540 = x + (x + 30)

2x + 30 = 540

       2x = 540

         x = 540/2

         x = 270

We got, the number of Passenger car sold (x) = 270

The number of SUV's sold = x + 30

The number of SUV's sold = 270 + 30 = 300

The catering cost was determined if the cost per person is R225,00. then the cost of 50 people is equal to = 1,125,000 R.

The catering cost was determined if the cost per person is R 225,00.​

The cost per person = 225,00 R

To calculate the cost per unit, add all of your fixed costs and all of your variable costs together and then divide this by the total amount of units you produced during that time period.

Let us assume,

Suppose you can find the cost for 50 people.

Then,

We can write,

Catering cost = x

x = 225,00 * 50

x = 1,125,000 R

Therefore,

The catering cost was determined if the cost per person is R225,00. then the cost of 50 people is equal to = 1,125,000 R.

The expression of f(x) = -2x² - 10 which is h(x) = -2x² - 6 would be vertically upward by 3 units, it becomes the graph of a function for f(x).

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

The function h is defined as follows.

h(x) = -2x² - 6

If the graph of his translated vertically upward by 3 units, it becomes the graph of a function for f(x)

To determine the expression for f(x).

Vertical shifting of a graph is done by adding any arbitrary constant to the function in shifting.

For example, If shift up by 1 unit,  add 1 to the function

If shift down by 4 units, subtract 4 from the function

Here h + 4 because adding 2 to the h coordinate would shift it up 2

⇒ h(f(x)) = ( x, y +4 )

⇒ f(x) + 4 = -2x² - 6

⇒ f(x) = -2x² - 6 -4

⇒ f(x) = -2x² - 10

Hence, the expression of f(x) = -2x² - 10 which is h(x) = -2x² - 6 would be vertically upward by 3 units, it becomes the graph of a function for f(x).

It is true. For all rational numbers a and b, a−b = a + (−b).

Given that,
To determine whether the statement, "For all rational numbers a and b, a−b = a + (−b)." is true or false.

In mathematics, a rational number is a number that can be described as the result of a fraction of value or does not have face value.

Here,
= a + (-b)
Since in the parenthesis there is a negative value, when we open the parenthesis the sign of the arithmetic operator will change accordingly,
So,
= a - b
So, the condition is true for all rational numbers.

Thus, It is true. For all rational numbers a and b, a−b = a + (−b).

P(x,y)----> P'(2h-x,2k-y)

P(-4,-4)---->P'(8,5)

Now comparing the corresponding sides;

2h+4=8

2h=8-4

2h=4

h=2

Again,

2k-y=5

2k+4=5

2k=5-4

2k=1
