marking brainlist. please help What is the first inverse operation for the following problem? 3x+4=12
Strike441 [17]

Answer:

3x + 4 = 12 :- x = 8 / 3

Step-by-step explanation:

3x + 4 = 12

Move all terms not containing x to the right side of the equation.

Subtract 4 from both sides of the equation.

3x = 12 - 4

Subtract 4 from 12.

3x = 8

Divide each term by 3 and simplify.

Divide each term in 3x = 8 by 3.

3x / 3 = 8 / 3

Cancel the common factor of 3.

Divide x by 1.

x = 8 / 3

The result can be shown in multiple forms.

Exact Form:

x = 8 / 3

Decimal Form:

x = 2.6

Mixed Number Form:

x = 2 2/3

The solution is shown below:

x^{2} +16 \\  \\ 
= x^{2} +(4)^{2} \\  \\ 
= x^{2} -(-1)(4)^{2}   \\  \\ 
= x^{2} -i^{2} (4)^{2} \\  \\ 
= x^{2} -(4i)^{2} \\  \\ 
=(x+4i)(x-4i)

What is the y-intercept of the line that passes
lara [203]

The slope is

\frac{-13-31}{1-(-10)}=-4

So, the equation is

y+13=-4(x-1)

The y-intercept is when x=0, so

y+13=-4(0-1) \\ \\ y+13=4 \\ \\ \boxed{y=-9}

A multiplier of 1.641 corresponds to a percentage increase or decrease of what percent?
bezimeni [28]

Answer:

A multiplier of 1.641 corresponds to a percentage increase or decrease of 64.1%.

Step-by-step explanation:

To determine a percentage increase or decrease of a certain number, a calculation consisting of the multiplication of said number by 1 plus the decimals corresponding to the percentage to be increased must be performed. Thus, for example, if you want to increase a number by 50%, you must multiply that number by 1.50. Therefore, if you multiply a number by 1,641, this implies that you are wanting to increase or decrease the initial number by 64.1%.
