Answer:

[tex]\mathrm{slope\:intercept\:form:\:y = \dfrac{ 1 }{ 2 } x+4}[/tex]

Step-by-step explanation:

To change the equation into slope-intercept form, we write it in the form y=mx+b

So this means that we have to solve for "y" in the equation "-x + 2y = 8"

−x + 2y = 8

Step 1: Add x to both sides

2y = 8 + x

Step 2: Now the equation is in standard form

2y = x + 8

Step 3: Divide both sides by 2

[tex]\mathrm{\dfrac{ 2y }{ 2 } = \dfrac{ x+8 }{ 2 }}[/tex]

Step 4: Dividing by 2 undoes the multiplication by 2

[tex]\mathrm{y = \dfrac{ 1 }{ 2 } x+4}[/tex]

Answer:

Nickels; 5 cents

Dimes; 10 cents

Given that she has 30 nickels:

30(nickels) x 5(a single nickel) = $1.50

2.40 - 1.50 = $0.90, those 90 cents leftovers should then be divided by 10 cents because one dime contains 10 cents and you want to figure out how many dimes there are:

90/10 = there are 9 dimes

Step-by-step explanation:

The First part is correct.

The domain is All set of inputs of a function.

We know that tangent has a period of 180.

Since our interval has a distance of 180, and tan 0 isn't 1 over root of 3, we will have only 1 domain.

So let solve the solution.

[tex] \tan(x) = \frac{1}{ \sqrt{3} } [/tex]

[tex]x = \tan {}^{ - 1} ( \frac{1}{ \sqrt{3} } ) [/tex]

30°

[tex]x = 30°[/tex]

So the domain of this function is [30°].

Part C: Tangent has a period of 180 degrees, so our solution will occur every 180 degrees.

We want full revolutions, so let use a variable, let say n to represent a interger.

Part C: The general solution is

30°+(180n)°, where n is a interger( 1,2,3.....)

Part D: The answer of tan x=1/sqr root of 3 is , in degrees, of

x∈N, 30+180n, where n is a interger.

The expression that is equivalent to [tex](3a)^{-2}[/tex] is [tex]\frac{1}{9a^{2} }[/tex].

Given expression is [tex](3a)^{-2}[/tex]

[tex]a^{-n} =\frac{1}{a^{n} }[/tex]

So, the given expression [tex](3a)^{-2}[/tex]can be written as [tex]\frac{1}{(3a)^{2} }[/tex]

[tex]\frac{1}{(3a)^{2} }= \frac{1}{3a*3a} =\frac{1}{9a^{2} }[/tex]

Answer: Quite simply: 2+x

A constant is simply a number, something that does not change: here it's "2"

A variable can change: here it's "x" - anything can be substituted for x

If we put those two together with a "+" sign, we get an expression: variables or constants (including multiple ones: such as 2x, which is a term) added to each other or subtracted from each other

Step-by-step explanation:

substitute a with 2 and b with 3

2x+3

because it's the same equation it should just be an equal sign.

Answer:

Simplifying

ax + b = 2x + 3

Reorder the terms:

ax + b = 3 + 2x

Solving

ax + b = 3 + 2x

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-1b' to each side of the equation.

ax + b + -1b = 3 + -1b + 2x

Combine like terms: b + -1b = 0

ax + 0 = 3 + -1b + 2x

ax = 3 + -1b + 2x

Divide each side by 'x'.

a = 3x-1 + -1bx-1 + 2

Simplifying

a = 3x-1 + -1bx-1 + 2

Reorder the terms:

a = 2 + -1bx-1 + 3x-1

Solution :-

Answer:

6m - 6

Step-by-step explanation:

9m + 2 - (3m + 8) = 9m + 2 -3m -8

= 9m - 3m + 2 - 8

= 6m - 6

when you open the brackets, -(+3m) = -3m because when a positive sign times a negative sign, you get a negative sign. so, same thing for -(+8) = -8

The difference in the price per bag for 150 bags versus 50 bags is $0.05 per bag

An equation is an expression that shows the relationship between two or more variables and numbers.

From the diagram:

Price for 150 bag = $38

Cost per bag = $40 / 150 = $0.25

Also:

Price for 50 bag = $15

Cost per bag = $15 / 50 = $0.30

Difference in price = $0.30 - $0.25 = $0.05
