what is the inverse of y + 6 = 3x?​

Answer:

x = ±2√3

Step-by-step explanation:

Step 1: Write equation

x² - 7 = 5

Step 2: Solve for x

Add 7 to both sides: x² = 12

Square root both sides: x = ±√12

Simplify: x = ±2√3

Step 3: Check

Plug in x to verify if it's a solution.

(2√3)² - 7 = 5

4(3) - 7 = 5

12 - 7 = 5

5 = 5

(-2√3)² - 7 = 5

4(3) - 7 = 5

12 - 7 = 5

5 = 5

Answer:

Step-by-step explanation:

Note that there are two scale models with each of ratio of 1/2 and 1/16 respectively.

For the first model, the dimension will be as follows:

Length/2 by width/2

94/2 by 50/2 = 47 feet by 25 feet.

For the second model, the dimension will be as follows:

Length/16 by width/16

The dimensions of the second model is 94/16 by 50/16 = 5.875 feet by 3.125 feet.

Since we are to solve for the area of the smallest scale model which is

5.875 feet by 3.125 feet.

Hence, area (A) = L× W

=5.875 × 3.125 feet.

= 18.359ft^2

Answer:

You multiply a factor in a multiplication equation.

In the given figure QT is of 16 units.

A line segment has two end points unlike a line which can extend indefinitely in both the directions.

According to the given question S is between Q and T and R is the midpoint of QS. RS=4 And RT= 12 we have to find QT.

As R is the midpoint of QS It will be twice of RS which

= 8 units.

And if RS is 4 units then QR is also 4 unit as R is the midpoint.

QT = QR + RT.

QT = 4 + 12

QT = 16 units.

Answer:

x is greater than or equal to -26

Step-by-step explanation:

We can use distributive property to solve the equation.

-6(x+4) in distributive property is:  -6x-24

-6x-24 is less than or equal to -5x+2

+6x                                             +6x

-24 is less than or equal to x+2

-2                                              -2

-26 is less than or equal to x

This means x is greater than or equal to -26

On the graph you would put a closed circle on -26 and point to the right.

In order to solve this question we use ratio and proportion

From the question

y = 20 when x = 8

So we have

If y is 20 when x is 8

Then when y is - 2 x is

[tex] \frac{ - 2 \times 8}{20} = - \frac{16}{20} = - \frac{4}{5} \\ [/tex]

Step-by-step explanation:

Scientific notations are the way through which a very small or a very large number can be written in shorthand. The height of angel falls, the tallest waterfall in the world in scientific notation is 3.212 × 10³ feet.

Scientific notations are the way through which a very small or a very large number can be written in shorthand.  In scientific notations when a number between 1 and 10s is multiplied by a power of 10.

For example, 6,500,000,000,000 can be written as 6.5e+12.

Given that the height of the angel falls is 3212 feet. Therefore, the height of the angel in the scientific notation is,

3212 feet

Multiply and divide the number by 1000, therefore, we can write,

= (3212/1000) × 1000 feet

= 3.212 × 1000 feet

= 3.212 × 10³ feet

Hence, the height of angel falls, the tallest waterfall in the world in scientific notation is 3.212 × 10³ feet.

Answer:

A negative value or minus sign (-).

Step-by-step explanation:

A grouping symbol can be defined as a set of symbol used for organizing multiple numbers or variables in an algebraic equation.

In Mathematics, there are basically three (3) main grouping symbols and these are;

1. Parentheses ( ).

2. Braces { }.

3. Brackets [ ].

Additionally, grouping symbols are used to determine the order of operation when solving an algebraic equation.

Hence, when distributing a negative sign in front of grouping symbols, you must multiply each term inside the grouping symbols by a negative value or minus sign.

For example, given the algebraic equation X = 20 - 2(-1 + 2 - 5)

We would simplify the numbers in the parentheses (grouping symbol) by multiplying with -2;

X = 20 + 2 - 2 - 10

X = 20 - 10

X = 10

Example 2;

-(-1 - 2 + 3 - 4)

We multiply each term inside the grouping symbol by the minus sign

1 + 2 - 3 + 4 = 4.
