Answer:

Step-by-step explanation:

The domain, the possible values of x, is only limited in this function when the function is undefined. Specifically division by zero is undefined. In this case x cannot be equal to 9 because that would lead to division by zero. And that is the only restriction. So the domain is all real numbers except 9. In interval notation this is

x=(-oo, 9),(9, +oo)

You would do the area of the big rectangle and subtract the areas of the two triangles. The triangles add up to 63 and the rectangle is 280 ft^2

Answer:

55

Step-by-step explanation:

9x + 1 = 7x + 13

x = 6

UW = 42+13

= 55

The two triangles are of congruent (SAS)

Answer:

the answer is c. the mode is w

Answer:

x > 7

Step-by-step explanation:

(Make sure to check with someone else to see if this is right)

Since she already spent $25 we can just subtract

60 - 25 = $35

So since she only has 35 dollars then she can only buy so many shirts, to find out how many you have to

35 / 5 = 7

So the inequality would be..

x > 7 pairs of shirts

Step-by-step explanation:

3/5 is the correct answer to this

Step-by-step explanation:

.41 is biggee than 3/5......

The option (D) "f(x) and g(x) are closed under the addition because when added, the result will be a polynomial is correct.

Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]

We have given two polynomials:

[tex]\rm f(x) = \rm a_0+a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]

[tex]\rm g(x) = \rm b_0+b_1x+b_2x^2+b_3x^3+b_4x^4..........b_mx^m[/tex]

If we add the above two polynomials:

= f(x) + g(x)

[tex]= (\rm a_0+a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n) + (\rm \rm b_0+b_1x+b_2x^2+b_3x^3+b_4x^4..........b_mx^m)[/tex]

The above expression is also a polynomial.

Thus, the option (D) "f(x) and g(x) are closed under the addition because when added, the result will be a polynomial is correct.

Answer:

x = 30.63

Step-by-step explanation:

Answer:

30.63

Step-by-step explanation:

We have, 160% × x = 49

or, 160/100 × x = 49

Multiplying both sides by 100 and dividing both sides by 160,

we have x = 49 ×

100/160 x = 30.63

If you are using a calculator, simply enter 49×100÷160, which will give you the answer.

The ratio of red to blue would be 60: 6 which can be simplified to 10:1.

The ratio of red to blue counters would be 60: 6 which can be simplified to 10:1

Ratio is the comparison of two quantities in terms of same units.

Example : If a & b be two numbers, then the ratio is a/b, where b≠0

Let Blue counters = x

Red counters would be = 3 times of blue counters = 3x

There are a total of 120 counters in a box.

First we have to find, the number of red and the number of blue counters:

3x + x = 120

⇒ 4x = 120

⇒ x = 120/4

⇒ x = 30

There are 30 blue counters.

Red counters = 3×30 = 90

Carl took 1/3 of the red, 90 / 3 = 30, so there were 60 red counters left in the box.

Kerry took 80% of the blue, 30 * 0.80 = 24, so there were 6 blue counters left in the box.

The ratio of red to blue counters would be 60: 6 which can be simplified to 10:1.

Answer:

x = 20

F = 46

Step-by-step explanation:

For x :

( 20 )  * 2 = 40

40 + 3 = 43

For degrees F

Add triangles have a angle sum of 180

So you just subtract 180 by the angles in the triangle

180 - 91 = 89

89 - 43 = 46

46 is remaining so it is the missing degrees ( F )

Question 4

The error was that in step 2, when distributing -3 into the parentheses, the person did not change the sign of 24 so that it was negative, since a negative number multiplied by a positive number will always make a negative number. Here is the correct way to solve this equation:

[tex]-5x+12-7x=-3(5x+8)\\-12x+12=-3(5x+8)[/tex]

Distrubute -3 into the parentheses

[tex]-12x+12=-15x-24[/tex]

Subtract both sides by 12

[tex]-12x+12-12=-15x-24-12\\-12=-15x-36[/tex]

Add 15x to both sides

[tex]-12+15x=-15x-36+15x\\3x=-36[/tex]

Divide both sides by 3

[tex]\frac{3x}{3} =\frac{-36}{3} \\x=-12[/tex]

Question 5

The error was that 2 was added on both sides in step 5 instead of being subtracted from both sides. Here is the correct way to do it, starting from step 4:

[tex]10=16x+2[/tex]

Subtract both sides by 2

[tex]10-2=16x+2-2\\8=16x[/tex]

Divide both sides by 16

[tex]\frac{8}{16} =\frac{16x}{16} \\\frac{1}{2}=x[/tex]

I hope this helps!
