Answer:

x+8 - 6/x+3

Step-by-step explanation:

Given the expression below

Step 1: Using PEMDAS rule

P=> Parenthesis

E=>Exponent

M=>Multiplication

D=>Division

A=>Addition

S=> Subtraction

From the rule above, we will start our simplification with the parenthesis

Step 1: simplify (5-4)

Step 2: Expand 2(1)=> 2x1, then simplify (6-2(1))

Step 3: Expand 6(4)=>6 x 4

Step 4: Add 8 and 24

Hence, the final answer is 32

Answer: your answer would be 32

Step-by-step explanation:

using PEMDAS we would first go by parentheses and use the order by each step.

Answer:

See below

Step-by-step explanation:

Slope of given line is 1      y = (1) x + 2

 parallel line has same slope

    so it will start to look like this    y = (1) x   + b

        sub in the point 5,7 to find b = 2

final answer y=x+2

The domain of the function is [1, ∞) and the range of the function is [0,∞).

Domain and range:

The domain and range of a function are  refers the set of all the inputs and outputs a function can give respectively.

Basically, domain takes all the possible input values from the set of real numbers whereas the range takes all the output values of the function.

Given,

Here we have the function

y = √x - 1

Now, here we need to find the domain and range of the function.

The given function is rewritten as,

√x - 1 > 0

Square both sides then we get,

x - 1 > 0

Add 1 on both sides then we get,

x > 1

Therefore, the domain is [1, ∞).

Similarly, let us consider, y ≥ 0

Therefore, the range is [0,∞).

If the cost to park in garage can be modeled by the equation P = 3+ch

Part A

The equation to find the number of hours a person parked h = (P-3) / c

Part B

If c = $2.25 and number of hours h =6 hours, then the cost to park in garage is $16.5

Part C

If P = $25.50, the person parked 10 hours if the cost per hour is $2.25

The flat fee of parking = $3

The cost to park in garage can be modeled by the equation

P = 3+ch

Where c is the hourly rate to park

h is the number of hours parked in the garage

Part A

The equation to find the number of hours a person parked is

P = 3+ch

c × h = P-3

h = (P-3) / c

Part B

c = $2.25

h = 6 hours

P = 3 + 2.25×6

= 3 + 13.5

= $16.5

Part C

P = $25.50

c = 2.25

h = (P-3)/c

= (25.50-3)/2.25

= 10 hours

Hence, if the cost to park in garage can be modeled by the equation P = 3+ch

The value of x is 10 and the length of SU is 50.

Here SU is the line and T is the mid-point of the line

So from this we have

SU = ST + TU

ST = TU

SU = 2ST = 2TU

ST = 3x - 5 and TU = 2x + 5

As ST = TU

3x - 5 = 2x + 5

x = 10

SU = 2ST

     = 2( 3x - 5)

     = 2( 3 × 10 - 5)

     = 2( 30 - 5)

     = 2× 25

     = 50

Therefore the value of x is 10 and the length of SU is 50.

Inequality: [tex]x-7\ge 15[/tex]

Solution: [tex]x\ge 22[/tex]

Inequality is a mathematical statement which depicts the relation between two or more mathematical variable or quantities which involves in relation which is not equal or inequal.

Given the statement is "A number decreased by 7 is at least 15"

Let the number be the variable x.

Now decreased by 7 = x-7

Suitable inequality sign for at least statement is [tex]\ge[/tex]

So the required inequality is given by,

[tex]x-7\ge15[/tex]

Solving the same we get,

[tex]x-7+7\ge 15+7[/tex]

Answer: f(3) = 0.84375

Step-by-step explanation:

f(3) is asking for the value of the function when x = 3, not multiplying f by 3. (f(x) is basically the output, y)

So we just plug in 3 for x and simplify (use PEMDAS)

f(3) = 2(0.75)^3

f(3) = 2(0.421875)

f(3) = 0.84375

Answer:

[tex]\frac{27}{32}[/tex]

Step-by-step explanation:

It may be a bit easier to represent 0.75 as a fraction, since we can use the following property of exponents: [tex](\frac{a}{b})^x = \frac{a^x}{b^x}[/tex]

We can represent 0.75 as: [tex]\frac{3}{4}[/tex]

And substituting this into the function we get: [tex]f(x)=2(\frac{3}{4})^x[/tex]

calculating the value when x=3, we get: [tex]f(3)=2(\frac{3}{4})^3[/tex]

using the property previously stated we get: [tex]f(3)=2(\frac{3^3}{4^3})[/tex]

Raising each value to the exponent we get: [tex]f(3)=2(\frac{27}{64})[/tex]

When we multiply by two, we can simplify by splitting up 64, into two factors: 2 and 32, to get: [tex]\frac{2*27}{32*2}[/tex]

From here it's easy to see that we can cancel out the values 2, to get: [tex]\frac{27}{32}[/tex]

In the year 2006, the total average credit card debt for a U.S. household was 10370 dollars.

We are given the expression that gives an approximate value of the total average credit card debt in a U.S. household (in dollars), t years after 1995 as;

420t + 5750

where t represents number of years after the year 1995. Thus, for the year 2006, the value of t is;

t = 2006 - 1995

t = 11 years

From concept of similar figure:

Similar figure means, that have the same shape and exactly the same in every way, on the other hand;

The similar figure means they are same shape but not the same size, then these figure is also called similar figure.

Now,

From concept of the congruent figure:

The congruent means, that two figure exactly the same that means, we can say that they are congruent, when both figure have same shape and same size.

So,

According to both concept, similar and congruent;

The given figure 1 and 2 is simililar, because of same shape. But due to different size, both figure have not congruent.

So, the given figures 1 and 2 is similar, but not congruent.
