Are the following lines parallel, perpendicular or neither?
y=6 and y = -6

Answer:

c = 55

Step-by-step explanation:

I would solve this by cross multiplying, but some teachers don't appreciate you skipping a step like that. Instead:

[tex]\frac{5}{2} =\frac{c}{22}[/tex]

First, multiply both sides by 2:

[tex]5=\frac{2c}{22}[/tex]

Then, multiply both sides by 22:

[tex]2c=110[/tex]

Now, just solve for c by dividing both sides by 2:

[tex]c=55[/tex]

Answer:

C = 55

Step-by-step explanation:

To figure out c you must first isolate c so there shouldn't be any other numbers or signs (addition, subtraction, division, and multiplication) on the same side of the equal sign as variable C.

The inverse of dividing 22 is multiplying 22 on both sides of the equation.

You would get 22/1 * 5/2 = C. 22 * 5 is 110 and 1 * 2 is still 2 so 110/2 = C.

Enter 110/2 into the calculator and you would get C = 55

Answer:

2.44

Explanation:

The number of 6.1% of 40 is 2.44.

Answer:

$6.00

Step-by-step explanation:

Total amount of money = 0.25q + 0.1d

where q is the number of quarters and d is the number of dimes

The problem states we have 18 quarters: d = 18

And that there are 15 dimes: d = 15

Plugging it in we get

= 0.25(18) + 0.1(15)

= 4.5 + 1.5

= 6.0

Answer:This is an exponential growth problem.  If the population doubles periodically, it follows a law like this:

P(t) = P(0)ekt

where P(0) is the initial population at time t=0, and k is a constant with units of years-1.

To find k, let t=0.  Then P(t) = P(0) = initial population = 5000.

Since the population doubles every 12 years, we can write

P(t+12) = 2P(t)

P(0)ek(t+12) = 2[P(0)ekt]

Simplifying,

e12k = 2

k = ln(2) / 12 = 0.0577623 years-1

Finally,

P(t) = 5000e0.0577623t, t in years

Then at t=48 years from now,

P(48) = 5000e(0.0577623 * 48) = 80,000

Graph 1 matches this data.  A line with a slope of 2.

Using inverse function concepts, it is found that the graph of f(g(x)) is given as follows:

On a coordinate plane, a straight line has a positive slope and goes through (-3,-3), (0, 0), and (3, 3).

When two functions f(x) and g(x), that are inverse of one another, are composed, that is, y = f(g(x)), the resulting function is given by:

y = x.

Hence the graph of f(g(x)) is given as follows:

On a coordinate plane, a straight line has a positive slope and goes through (-3,-3), (0, 0), and (3, 3).

Answer:for a graph u use rise over run. If u just have the points u use the formula which is m=y2-y1/x2-x1

Step-by-step explanation:

If f^(-1) is the inverse of f, then

f(f^(-1)(x)) = x

It looks like f(x) = (x + a)/x. This gives us

f(f^(-1)(x)) = (f^(-1)(x) + a)/f^(-1)(x) = x

Solve for f^(-1)(x) :

f^(-1)(x) + a = x f^(-1)(x)

f^(-1)(x) - x f^(-1)(x) = -a

(1 - x) f^(-1)(x) = -a

f^(-1)(x) = -a/(1 - x)

f^(-1)(x) = a/(x - 1)

If a = 4, then the inverse is f^(-1)(x) = 4/(x - 1).

Answer:

1

Step-by-step explanation:

it can't be 2 because a slope is always in the mid or after a starting point I think..

Hello there! (:

To find the slope of this graph, we must calculate the rise over the run.

The rise is the amount of units we move up or down; the run is the amount of units we move right or left.

So here, we move 2 units up and 4 units to the right:

[tex]\frac{2}{4}[/tex]

We can reduce our fraction (divide the top and bottom by 2):

[tex]\frac{1}{2}[/tex]

Answer:

2

Step-by-step explanation:

Here we're "evaluating," not solving, the given expression.

Substitute -2 for x and 6 for y:

20 - (-2)^2      20 - 4

--------------- = -------------- = 16/8 = 2

(6) - (-2)              8

The value of this expression, when x = -2 and y = 6, is 2.

Answer:

$480

Step-by-step explanation:

They sold the machine for $400 but made a profit of 20%.

This mean you would take 400 × .20

This gives you 80

That means the retailer got an extra 20% or $80

for the washing machine.

$400 + $80 = $480

Step-by-step explanation:

Answer:

w = 9

Step-by-step explanation:

- 3w + 15w + 7 = 8w + 43 , simplifying

12w + 7 = 8w + 43 ( subtract 8w from both sides )

4w + 7 = 43 ( subtract 7 from both sides )

4w = 36 ( divide both sides by 4 )

w = 9

W=9

first, you simplify the expression.

12w + 7 = 8w + 43.

After that, we group all the w terms on the left side of the equation.

Subtract 8w from both sides:

12w + 7 - 8w = 8w + 43 - 8w

Group like terms:

12w - 8w + 7 = 8w + 43 - 8w

Simplify the arithmetic:

4w + 7 = 8w + 43 - 8w

Group like terms:

4w + 7 = 8w - 8w + 43

Simplify the arithmetic:

4w + 7 =43

Then, we group all constants on the right side of the equation

Subtract 7 from both sides:

4w + 7 - 7 = 43 - 7

Simplify the arithmetic:

4w = 43 - 7

4w = 36

Now, we isolate the w. Divide both sides by4:

4w / 4 = 36 / 4

Simplify the fraction:

w = 36/4

Find the greatest common factor of the numerator and denominator:

w = 9 × 4/1 × 4

Factor out and cancel the greatest common factor:

w = 9

Answer:

-2, as the expression is written

Step-by-step explanation:

It depends on how one interprets the expression.  The expression, as written, is:

4+24÷-6×2=

A fundamental rule in math is known as PEMDAS.  This acronym describes the order of operations that are to be followed when solving mathematical expressions.  PEMDAS stands for

P- Parentheses,

E- Exponents,

M- Multiplication,

D- Division,

A- Addition, and

S- Subtraction.

The use of parentheses is critical in math expressions, as we will see here.  

The are no parentheses in "4+24÷-6×2=."  So we will follow the steps are shown above:

Multiplication:  4+24÷-6×2 = 4+24÷-12

Division:    4+24÷-12 = 4+-2

Addition:  4+-2 = 2

The expression as written is equal to 2.

But if parentheses were included in the origianl proble, the answer might be different.  For example:  

(4+24)÷-6×2=

Parentheses:  (4+24)÷-6×2=  (28)÷-6×2=

Multiplication:  (28)÷-6×2= (28)/-12

Division:  (28)/-12 = -2.333 . . .
