Answer:

[tex]m=\frac{8}{5}[/tex]

Step-by-step explanation:

Answer:  The slope is  -8/5

Step-by-step explanation:

Using the located points  (-1,4)     and  (4,-4)  we will find the difference in the y coordinates of the points and divide it by the difference in the  x coordinates of the same points.  

Difference in y:  4 - (-4)  =  8

Differecence in x  -1 - 4 = -5

Slope:    8/-5

Answer:

C

Step-by-step explanation:

The domain of the given function is  {–2, 0, 2} while range is {4, 0} so option (C) will be correct.

A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.

Given the function,

An arrow goes from negative 2 to 4, 0 to 0, and 2 to 4.

So,

-2 → 4 , 0 → 0 and 2 → 4

Since the domain is a set of input values here input is -2,0 and 2.

So

Domain = {-2,0,2}

And the range is a set of output values here output is 4, 0

So,

Range = {4,0}

Hence "The domain of the given function is  {–2, 0, 2} while range is {4, 0}".

Answer:

17% of the bill

Step-by-step explanation:

Well to find the answer to this question we first have to add 35 + 48 to get the total percent of the bill that Michelle and Lori paid.

35 + 48 = 83%

now that we know the percent of the bill that Lori and Michelle are paying we have to subtract that amount by 100% to get the percent of the bill that Patti is paying.

100% - 83% = 17%

So Patti is paying 17% of the bill

If we wanted to go even farther and find out what 17% of the bill was all we would have to do is multiply 45 by 17% or 45 x 0.17

45 x 0.17 = 7.65

So Patti is paying 7 dollars and 65 cents

Answer:

Option D

Step-by-step explanation:

According to law of cosines =

[tex] {a}^{2} = {b}^{2} + {c}^{2} - 2bc. \cos(A) [/tex]

where 'a' is the uknown side , 'b' & 'c' are the given sides and angleA is the angle opposite to the uknown side i.e. opposite to 'a'.

Using the Law of cosines , we'll find the length of AC .

[tex] {ac}^{2} = {7}^{2} + {13}^{2} - 2 \times 7 \times 13 \times \cos(50) [/tex]

[tex] = > {ac}^{2} = 49 + 169 - 182 \times 0.76[/tex]

[tex] = > {ac}^{2} = 218 - 138.8 = 79.68[/tex]

[tex] = > ac = \sqrt{79.68} = 8.92 = 9(appx)[/tex]

In option D , if we'll round of 8.86 , then its appx 9. So option D is right

Answer:here are approximately 143 women

Step-by-step explanation:

Step 1

Given that for every 19 women, there are 81 men in the United States Air Force therefore we can say the ratio between the men and women is given as 81:19

such  that the fraction to represent men = ratio of men/ total ratio of men and women

81/(19 + 81)= 81/ 100 =0.81

and the fraction to represent women = ratio of women/ total ratio of men and women

19/(19 + 81)= 19/ 100 = 0.19

Step 2-

To calculate the number of men in a 750 squadron, we have that

fraction of men x number of members

=0.81 x 750= 607.5 ≈ 608

To calculate the number of women in a 750 squadron, we have that

fracton of women x number of members

=0.19 x 750= 142.5 ≈ 143

Therefore there are approximately 143 women .

Answer:

the middle one because HL is hypotenuse-leg and the middle one is the one that has a congruent hypotenuse and a congruent leg

(HL theorem only works with a right triangle)

Step-by-step explanation:

The pair of triangles that can be proven congruent by the HL theorem is the triangles in the middle.

According to the HL Theorem:

A triangle would contain:

Therefore, we can see that the pair of triangles in the middle of the diagram are congruent through the HL theorem as they satisfy the conditions.

Answer:  3 necklaces and bracelet sets can be made from the  28 1/3 inches of wire.

Step-by-step explanation:

step 1

LET  I set of necklace and bracelet be represented as ( A bracelet and a necklace)

 if Tominka uses 6 1/9 inches of wire to make a necklace and 3 1/3 of wire to make a bracelet  for a set

Then Total Length of wire that can be used for a set = 6 1/9 inches+ 3 1/3 inches = 9 (1+ 3)/9

= 9 4/9 inches.

Step 2

IF  a set (One necklace and bracelet) can use = 9 4/9 inches

and Total wire used = 28 1/3inches

Then Number of  necklaces and bracelet sets that can be made  from the 28 1/3 inches wire = 28 1/3inches /9 4/9 inches

=85/3 / 85/ 9  = 85/3  x 9/ 85  = ( 85 cancels 85 )

9/3 = 3

 3 necklaces and bracelet sets can be made from the  28 1/3 inches of wire.

Answer:

1. y=3x-2

2. y=-1/4x+5

These equations are in slope-intercept form (y=mx+b). IN this equation m represents the slope and b represents the y intercept. Therefore, y=3x-2 and y=-1/4x+5 are correct

Step-by-step explanation:

Answer:

A) 180+15x=500

B) 21 people.

Step-by-step explanation:

$180

so 500-180 is 320.

320/15 is 21 1/3

So, Ms. Douglas can take 20 students and herself :)

Part A:

180+15x=500

180-180+15x=500

15x=320

x=21 1/3, so Ms. Douglas can afford to take 21 people,, but one of them is herself.

Hope this helps pls hit the crown :D

Answer:

A. 500 = 180 + 15x

So Ms.Douglas has a budget of $500 and she is going to spend $180 going to and from school on a bus. 180 is your constant. It is $15 per person to enter the gate of the amusement park and 15 is your variable.

So 500 = 180 +15x

Step-by-step explanation:

B. 500 = 180 + 15x

320 = 15x

x = 21.333333

but since we are talking about people here Ms.Douglas can only take 21 people

I hope this helps

Answer:

y = 17(7) + 6

Step-by-step explanation:

Given that:

Amount owed = $125

Payment per week = $7

Number of whole weeks to pay :

$125 / $7 = 17.85 = 17 whole weeks

$125 - (17 * 7) = $125 - $119 = $6

Using slope intercept notation :

y = mx + c

Where m = slope ; c = intercept. ;

m = 17,; x = $7, c = $6

y = 17(7) + 6

Answer: Choice C.

How many 1/4-meter long pieces of ribbon are needed to have a total of 3 1/2 meters of ribbon.

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

Explanation:

Let's consider a similar problem without the fractions.

Let's say you want to know how many 2 meter lengths of ribbon you can cut from an overall length of 24 meters. That would be 24 ÷ 2 = 12 pieces total.

So we divide the two values (large ÷ small)

The same idea applies to this problem as well. The larger amount (3 & 1/2 meters) is what we cut up, and each slice is 1/4 of a meter. To find the number of pieces, we would compute 3 1/2÷1/4

Note: it might help to convert the mixed number 3 & 1/2 to the improper fraction 7/2

Step-by-step explanation:

Answer:

I would say it's B. false

Answer:

False

Step-by-step explanation:

Look at the inputs (x-values)

If the inputs are the same, the relationship is Not a function.

Inputs (x-values), cannot share the same output (y-values).

Example:

Inputs      Outputs

3              2    

2              5

8              5

3              6

In the input there are two 3's which causes this to not be a function.

(Outputs can have the same numbers repeating just not inputs.)
