-4n-5

It is composite because it can be divided by 2 and 4.

Answer:

18).

[tex]n + 4 - 9 - 5n \\ = (n - 5n) + (4 - 9) \\ = - 4n - 5 \\ = - (4n + 5)[/tex]

20).

It is a composite number, because it had more than two factors

Answer:

K and L2 are  perpendicular.

Step-by-step explanation:

Assume the slope of L1 is X. The slope of L2 is also X.

Using perpendicular slopes, the slope of K is -1/x, meaning it is perpendicular to both L1 and L2.

Answer:

Simply move the graph to the right 3 units.

Step-by-step explanation:

The minus 3 on the inside with the x means you move horizontally and to the right.

If you had a plus 3 then it would move it to the left.

Step-by-step explanation:

86 = 1,2,43,86

7 = 1,7

12 = 1,2,3,4,6,12

77 = 1,7,11,77

38 = 1,2,19,38

52 = 1,2,4,13,26,52

9 = 1,3,9

73 = 1,73

98 = 1,2,7,14,49,98

24 = 1,2,3,4,6,8,12,24

6 = 1,2,3,6

80 = 1,2,4,5,8,10,16,20,40,80

Answer:

Let the number be x

half the number can be written as

x/2

then 5 less than half of the number can be written as

(x/2) - 5

Answer:

y=-1/6x-2

Step-by-step explanation:

Answer:

x = 34

Step-by-step explanation:

As we know that ∠DPC is right angle

so we just need to find the value of x

∠DPC = 90

2x + 22 = 90

2x = 90 - 22

2x = 68

x = 68/2

x = 34

we can even cross-check

2x + 22 = 90

2 (34) +22 = 90

68 + 22 =90

90 = 90

thus cross-checked

Answer:

True

Step-by-step explanation:

Since the absolute value of a number is just how far that number is from zero all numbers inside an absolute value marking become positive. So, the answer is true.

Step-by-step explanation:

Domain of h(x) is

[tex]\Bbb{R}\backslash\{x=-3\}[/tex]

or equivalently,

[tex](-\infty,-3)\cap(-3,+\infty)[/tex]

since h(x) is undefined everywhere except when x=-3.

The range of f(x) is

[tex]\Bbb{R}[/tex]

or equivalently,

Answer:

p=49 n=76 (b)

Step-by-step explanation:

p+n=125

p+3.52n=316.52

Therefore:

p=125-n

Now if we plug in for p

125-n+3.52n=316.52

Now solve

-125 both sides and simplify=

191.52 = 2.52n

Now divide

n=76.

Now plug in 76 for the top one

p+76=125

Simplify=

p=49

Hope this Helped <3

Answer:

A

Step-by-step explanation:

Let's subract both these equations.

P+N = 125

and

P+3.52N = 316.52

2.52 = 191.52

191.52/2.52 = 76

P = 76

76 + N = 125

N = 49

Check:

49 + 76 = 125

Answer:

  x -2y = 14

Step-by-step explanation:

The x- and y-coefficients can be the same. The constant needs to change to make the given point satisfy the equation.

  x -2y = (2) -2(-6) . . . . . use (x, y) = (2, -6) to find the constant

  x -2y = 14

I'll do the first five problems to get you started.

===========================================================

Problem 1

Subtraction can be thought of as adding a negative.

So -3 - 6 is the same as -3 + (-6)

We can think of an example involving money

-3 means we're 3 dollars in debt. Then -6 means we go 6 dollars further into debt. Therefore, the total debt is -3 + (-6) = -9 so overall we're 9 dollars in debt.

===========================================================

Problem 2

When subtracting a negative, the two will cancel out to form a positive. This is because negatives are opposite in nature. Two opposites undo one another.

So with all that in mind, something like 10 - (-4) will become 10 + 4

===========================================================

Problem 3

It's the same idea as the previous problem, but we're dealing with different numbers of course.

===========================================================

Problem 4

We'll use the ideas mentioned in problem 1. There's not much further to explain here.

===========================================================

Problem 5

Refer back to either problem 2 or problem 3 for a similar example. The negatives will cancel to form a positive.

Answer:

multiply both sides by 8 then divide by -3

or in one step divide both sides by (-3/8) which is the same as multiplying by

(-8/3)...

Answer:

CODE: 2 - 1 - 6 - 3

Step-by-step explanation:

1. x - 35 = 27    => x = 62

2. -96 = -8x      => x = 12

3. 6 = x/4 + 2    => x = 16

4. 76 - 3x = -29 => x = 35

CODE: 2 - 1 - 6 - 3

Answer:

(5) 84° and 96° ; (6) 40° and 50°

Step-by-step explanation:

5) Supplementary angles are in the ratio 7 : 8

So 7x + 8x = 180°

15x = 180

x = 180/15

x = 12

The angles are 7x = 7 * 12 = 84° ; 8x = 8 * 12 = 96°

6) Complementary angles are in the ratio 4 : 5

So 4x + 5x = 90°

9x = 90

x = 90/9

x = 10

The angles are 4x = 4 * 10 = 40° ; 5x = 5 * 10 = 50°
