Answer:

-12x+27

Step-by-step explanation:

blah blah blah blah blah

Answer:

The answer is -12x+27

Step-by-step explanation:

You would just multiply the equation

-3(4x-9)

-3*4x =-12x

-3(-9)=27

it's a positive because a negative plus a negative equal a positive.

-12x+27

Hope this helps please mark brainliest :)

Answer:

Divide the number by two.

Step-by-step explanation:

For example 50% of 50 is 25, because 50 ÷ 2 = 25.

LETS USE COMBINATION AS ORDER IS MANDATORY HERE

Answer:

$8.11

Step-by-step explanation:

Original Price: $16.95

Discount: 54% Decimal Form: .54

Tax: 4% Decimal Form: .04

Let's start with the discount...

16.95 x .54 =9.153 Round = 9.15

16.95 - 9.15=7.80

Now, for the tax..

7.80 x .04=0.312 Round = 0.31

7.80 + 0.31=8.11

Hence. the Selling price is $8.11

Answer:

D. is the answer to your question

Answer:

120/99 is the answer.

Step-by-step explanation:

It has a line over it means that after the point there are infinite numbers of 21.

•Multiply 1.212121... with 100

we get 121.212121...

•Subtract it with the original one

121.212121.. - 1.212121... = 120.000.. = 120

Write it as an equation :-

Let the fraction be x.

(100×x) - x = 120

100x-x = 120

or, 99x = 120

so, x = 120/99

standard deviation is a measure of how many data points different from the mean each individual data point is.
if the standard deviation is 7, the range is +7 and -7 68% of the time
the data will be within 2 standard deviations +14 -14 95% of the time
the data will be within 3 standard deviations +21 -21 99.7% of the time

Answer: 2

Step-by-step explanation: Since the y value is 2 when the x value is zero, the initial value is 2.

Answer:

A

Step-by-step explanation:

An asymptote is a line that a curve approaches, as it heads towards infinity.

It is easy to spot the asymptotes for any given rational function - simply work out which value of x would make the denominator zero.

Function A has asymptotes at x = -3 and x = 7.  This is consistent with the graph, where the asymptotes are marked as red dash lines at x = -3 and x = 7

For info, function D has asymptotes at x = -7 and x = 3.  So the shape of the curve would be the same as the given diagram, but it would be 4 units to the left.

Answer:

  x° = 54.5°

Step-by-step explanation:

The measure of angle x is half the difference of the intercepted arcs. The larger arc is shown as 141°. The smaller one must be computed from the arcs shown:

  360° -187° -141° = 32°

So, the measure of x° is ...

  x° = (141° -32°)/2

  x° = 54.5°

Answer:

False equation:   -2|8 - 6| - 6 = -10

Step-by-step explanation:

-2|8 - 6| - 6 = -12                True or false?

-2 | 2| - 6 = -12                    Substract 8 - 6 = 2

-2 × 2 - 6 = -12                    |2| = 2  absolute value of 2 is 2

- 4 - 6 = -12                         -2 × 2 = -4 ( negative times positive = negative)

 -10 = -12                            False

Answer: He received a discount of $11.40.

Step-by-step explanation:

To answer this problem we can look at the discount he was given, in this case, it would be 30%.

We can then turn that 30% into a decimal by dividing it by 100.

30/100

This gives us 0.3

After knowing this, we simply multiply 0.3 by the original price of $38.00 and it gives us a discount of $11.40.

Answer:

9 x n - 2

to do this, think in this way:

two less than (the product of 9 and a number) is the same thing as saying

(the product of nine and a number n ) subtracted by two

you could also represent this as:

(-2) + (9 x n)

Answer: 35log4x

Step-by-step explanation:

Answer:i think it may be 526.25

Step-by-step explanation:

meal cost for the trip: 5x10=$50

Hotel cost for the trip: 5x25.25=$126.25

plane fare: $350

350+50=400

400+ 126.25=$525.25

Step-by-step explanation:

A right triangle must have one angle that is equal to exactly 90 degrees.

Answer:

  c. x about 57/16

Step-by-step explanation:

You have not specified the algorithm you use for one iteration. We will define it as follows:

The starting point is a pair of numbers that are upper and lower bounds on the solution. The iteration ends when a new value replaces one of these bounds. The final estimate of the root will be the average of the latest upper and lower bounds.

__

The given graph shows suitable initial bounds are 3 and 4. The sign of h(x) = f(x)-g(x) matches the sign of h(3) when x=7/2, so the value 7/2 will replace the lower bound at the end of iteration 1.

The new average of upper and lower bounds is (7/2 +4)/2 = 15/4. The sign of h(15/4) matches the sign of h(4), so 15/4 becomes the new upper bound at the end of iteration 2.

The new average of the bounds is (7/2 +15/4)/2 = 29/8. The sign of h(29/8) matches the sign of h(15/4), so 29/8 becomes the new upper bound at the end of iteration 3.

After 3 iterations, the bounds are 7/2 and 29/8. The average of these values is the approximate solution to the equation:

  x = (7/2 +29/8)/2 = 57/16

Additional comment

We have tried to be clear about what we consider to be one iteration, and how a root approximation is arrived at. The definition of these things provided by your curriculum materials may be different.

Answer:

40.56 ft

Step-by-step explanation:

The perimeter of a circle is equivalent to [tex]2\pi r[/tex], where r = radius. Therefore, the perimeter of a semicircle should be [tex]\frac{2\pi r}{2}[/tex]

In this case, we're given the diameter of the semicircle as 8, so we divide the diameter by 2 and get the radius as 4. Now, let's solve the circumference of the semicircle.

Now, we're given the lengths of the rectangle as 8, 10, and 10. The perimeter of the rectangle (excluding the inner side) is 28.

28 + 12.56 = 40.56

Therefore, the perimeter is 40.56 ft.
