Answer:

3 * (x + 7)

Step-by-step explanation:

Mark number as x

Then the sum of a number and seven is x + 7

Three times x + 7 can be written as

3 * (x + 7)

Parentheses mean that we first add x and 7 and then multiply their sum by 3

Alternatively you can write it as 3x + 21, since

3 * (x + 7) = 3 * x + 3 * 7 = 3x + 21

Find:

Value of equation

Computation:

(9x² - 2x + 1) - (3x² + 5x - 8)

(9x² - 2x + 1 - 3x² - 5x + 8)

Step-by-step explanation:

x = -4/5 = -0.8

Answer:

x = −0.8

Step-by-step explanation:

−2.7 + x = −3.5

1.) Simplify both sides of the equation

x − 2.7 = −3.5

2.) Add 2.7 to both sides

x − 2.7 + 2.7 = −3.5 + 2.7

AND BAYUM...

x = −0.8

Answer:

[tex]-0.5n^{4}[/tex] or [tex]-\frac{1}{2} n^{4}[/tex]

Step-by-step explanation:

To simplify a dividing exponent, use the "Quotient of Powers" law: [tex]\frac{a^{m} }{a^{n} } = a^{m-n}[/tex]. In this situation, the equation would be: [tex]\frac{-9}{18} n^{6} -n^{2}[/tex] or [tex]-0.5n^{4}[/tex] (-0.5 is also [tex]-\frac{1}{2}[/tex]).

Answer:

A. (2,-6)

Step-by-step explanation:

(×-2)²+(y+6)²=10

Equating it with

(×-h)²+(y -k)²=10

h = 2 & k = - 6

(h, k) = (2, - 6)

Answer:

29/6

Step-by-step explanation:

Answer: 29/6 or 4 5/6

Step-by-step explanation:

3+1 = 4

Find a common denominator between 1/2 and 1/3

1/2 becomes 3/6 and 1/3 becomes 2/6

2/6 + 3/6 = 5/6

Now add the 4 back:

Answer:

x = 1/3(500 + 5y)

Step-by-step explanation:

Given that:

x child tickets for $3

y adult tickets for $5

3x + 5y = 500

To solve for x

3x = 500 + 5y

Divide through by 3

3x /3 = 500/3 + 5y/3

x = 1/3(500) + 1/3(5y)

x = 1/3(500 + 5y)

2.)

If the total number of tickets sold was made available, then a more direct solution would have been obtainable as we can have two different equations;

One for the total number of ticket sales and the other of the total revenue from ticket sales.

Answer:

Step-by-step explanation:

The product of slopes of perpendicular lines is -1

y = 2x − 4  ⇒   m₁ = 2

m₁m₂ = -1

2m₂ = -1

m₂ = -¹/₂

The Point-Slope form of equation of a line with slope of "m" and passing through point (x₁, y₁) is:  y - y₁ = m(x - x₁)

m = -¹/₂

(4, 3)  ⇒  x₁ = 4,  y₁ = 3

So the equation in point-slope form:

                                                  y - 3 = -¹/₂(x - 4)

Therefore:

y - 3 = -¹/₂x + 2

y = -¹/₂x + 2 + 3

Step-by-step explanation:

Four friends go out to lunch together.

For what number of toppings is the price of a personal pizza the same as a calzone?

Let us represent the number of toppings as x

We need to know the price of a personal pizza and the price of a calzone

Mike orders a personal pizza with 2 toppings for $7.00.

2x = $7

x = $7/2

x = $3.50

Dustin orders a personal pizza with 5 toppings for $9.25.

5x = $9.25

x = $9.25/5

x = $1.85

Lucas orders a calzone with 1 topping for $5.75.

x = $5.75

Will orders a calzone with 4 toppings for $8.75.

4x = 8.75

x = 8.75/4

x =2.1875

Answer: 80% views are added

Step-by-step explanation:

The required  daily percent change in the views of the video is 50%.

Nina uploaded a funny video on her website, the relationship between the elapsed time t, and number of views. V(t) is V(t)=500⋅(1.8)t.

Rate of change is defined as the change in value with rest to the time is called rate of change.

Here,
V(t)=500⋅(1.8)t
The slope of the given relationship will describe the the daily percent change in the views of the video i.e.
m = 500*1.8
m = 900
since the rate of increase in views in each day is by 900.

Now the percentage change per day.
= 900/1800 x 100
= 50 %

Thus, the required  daily percent change in the views of the video is 50%.

Express x^2 - 9 as difference of two squares

[tex]\frac{(x^2 -3^2)(x+2)}{x(x^2-x-6)}[/tex]

[tex]\frac{(x -3)(x+3)(x+2)}{x(x^2-x-6)}[/tex]
