Answer:

y=-1/5+1

Step-by-step explanation:

Answer:

y = -1/5x + 1

Step-by-step explanation:

In these types of problems you want to guesstimate the slope and draw an imaginary solid line amongst the dots. The slope you'll end up with is -1/5 because the graph is decreasing.

and just to check, i typed this into my graphing calculator and can confirm this as the answer. :)

Answer:

<

Step-by-step explanation:

0.8 is bigger than 0.799

0.799 < 0.8

Answer:

g = 118 degrees

h = 62 degrees

k = 98 degrees

m = 82 degrees

Step-by-step explanation:

180-118=62

180-98=82

g = 118(Opposite to other one)

h =  62 (180 - 118)

m =  82 (180 - 98)

k = 98 (Opposite to other one)

Answer:

its Combine like terms sorry the answer is kind of late

Step-by-step explanation:

The first step in solving the given equation is Combine the like terms.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given is an equation,

gx + 3x + 2 = 57

Like terms are terms which are having the same variable or they are constants.

Here gx and 3x are like terms since both of then has the variable x.

2 and 57 are constants.

gx + 3x + 2 = 57

Combine the like terms.

(g + 3)x = 57 - 2

(g + 3)x = 55

Hence the first step is combining like terms.

Answer:

C. \(9^{-2} = \frac{1}{81}\)

Step-by-step explanation:

Given

\(9^{x}\)

Required

Find the expression where x - 2

\(9^{x}\)

Substitute 2 for x

\(9^{-2}\)

From law of indices which states

\(a^{-b} = \frac{1}{a^b}\)

So, the expression becomes

\(9^{-2} = \frac{1}{9^2}\)

Expand the denominator

\(9^{-2} = \frac{1}{9 * 9}\)

\(9^{-2} = \frac{1}{81}\)

Hence, \(9^{x}\) is \(\frac{1}{81}\) when x = 2

19. Distributive property is multiplying everything outside of the parenthesis by everything in them!

Let's do it

2(3x + 4y)

We will multiply 2 by 3x and 2 by 4y

2 × 3x + 2 × 4y = ?

6x + 8y

20. Solving algebraically is using multiplication and division, addition and subtraction!

5h = 25

divide 25 by 5 to find h

h = 25/5

h = 5

2 + c = 12

subtract 2 from both sides

2 + c - 2 = 12 - 2

c = 12 -2

c = 10

3y + 10 = 40

We need to do subtraction and division for this one!

Let's subtract 10 from both sides

3y + 10 -10 = 40 - 10

3y = 30

Divide 30 by 3 to find y

y = 30/3

y = 10

22. To find equivalent ratios, let's simplify them!

To simplify ratios, we need to find the highest common factors

a. 2:6

The highest common factor between 2 and 6 is 2, so let's divide both sides by 2

We get ... 1 : 3

b. The highest common factor between 12 and 30 is 6, so let's divide both sides by 6

We get ... 2 : 5

23. To find how many songs are played during a certain amount of time, all we need to do is multiply 12 (the amount of songs played in 1 hour) by however many hours they say!

This can be expressed like this

a. # of songs = 12 × h

Now let's use this expression to answer the next two parts of this question!

b. to find the "# of songs" played in 24 hours, all we need to do is multiply 12 by 24! 24 will be the "h" in our expression. h is the number of hours

Here's what it looks like using our expression we made

# of songs = 12 ( 24)

Solve using a calculator

# of songs = 288

c. To find how many hours it will take to play 60 songs, we will put it in place of the LEFT SIDE of the equation that says "# of songs"

Let's solve it now!

It looks like this ... 60 = 12h

Let's divide to find the number of hours!

60/12 = h

60/12 = 5

It will take 5 hours to play 60 songs!

Answer:

x = 7

Step-by-step explanation:

150 + x² = 199

=> 199 - 150 = x²

=> 49 = x²

=> x = 7

Hoped this helped.

Answer:

x=7

Step-by-step explanation:

199 minues 150 is 49

the square root of 49 is 7

x is equal to 7

The correct answer to the problem is x=7

Answer:

k=69

Step-by-step explanation:

(plug in 69 instead of k)

69/3 = 23.

23+1=24

The ≥ sign means 21 has to be GREATER or EQUAL to 17.

Answer:

The mode is equal to the minimum

Is the correct answer

Step-by-step explanation:

In this case,

Mean = (52+48+48+54+50)/5

Mean = 50.4

The Median = 50,(the middle value)

Mode = 48  (the value that appears most often)

Now, the minimum value(smallest value) of the data set is 48

so,

The mode is equal to the minimum

Answer: the mode is equal to the minimum

Step-by-step explanation:

Answer:

3/4

Step-by-step explanation:

Since (p, r) lies on the line y = x + b,

we have,

r = p + b -----eq(1)

Since (2p, 5r) lies on the line y = 2x + b,

we have,

5r = 2(2p) + b -----eq(2)

Sub the value of r from eq(1) in eq(2),

5(p + b) = 4p + b

⇒ 5p + 5b = 4p + b

⇒ 5b - b = 4p - 5p

⇒ 4b = -p

⇒ b = -p/4

sub in eq(1)

r = p + (-p/4)

= p - p/4

= 3p/4

⇒ r = 3p/4

⇒ r/p = 3/4

Answer:

3/4

Step-by-step explanation:

We have two lines:

r = p + b     eq(1)

5r = 4p + b   eq(2)

eq(2) - eq(1)

4r = 3p

dividing by 4p

r/p = 3/4

A+56=9(A)

56+9A

A=7

he will be 7 years old he is pretty old

Answer:

Kevin is 7 years old right now.

Step-by-step explanation:

Let x be Kevin's age right now, that's what we're trying to find.

In 56 years, he'll be 9 times older than he is now, so we can say:

x + 56 = 9x

Now we can get the x values on the right side of the equation so that:

56 = 8x

Now solve for x and you have his current age which is 7.

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

Answer:

r = 1

Step-by-step explanation:

The equation is,

→ 6r - 1 + 6r = 11

Now the value of r will be,

→ 6r - 1 + 6r = 11

→ 12r = 11 + 1

→ r = 12/12

→ [ r = 1 ]

Hence, the value of r is 1.

Answer:

The answer is 1 r is equal to 1
