I need help with 14 and 15

Answer:

(14, - 13 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ [tex]\frac{1}{2}[/tex] (x₁ + x₂ ), [tex]\frac{1}{2}[/tex] (y₁ + y₂ ) ]

let (x₁, y₁ ) = (- 2, - 7) and (x₂, y₂ ) = (x, y)

Using the midpoint formulae equate to the coordinates of the midpoint.

[tex]\frac{1}{2}[/tex] (- 2 + x) = 6 ( multiply both sides by 2 )

- 2 + x = 12 ( add 2 to each side )

x = 14

and

[tex]\frac{1}{2}[/tex] (- 7 + y ) = - 10 ( multiply both sides by 2 )

- 7 + y = - 20 ( add 7 to both sides )

y = - 13

Thus

coordinates of other endpoint = (14, - 13 )

Answer:

I guess the answer is going to be 9/5

What i did is. First i divided the cost of a dozen. And i took of a dozen of 18 (your cookies) and was left with 6 cookies. i also was left with 9 after dividing so if you add 6+9 so your answer is 15

Answer: For 18 cookies, the cost is 27 dollars.

Step-by-step explanation:

So we are given that:

a dozen cookies cost $18

And we have to find how many 18 cookies cost. We can solve this problem by finding the ratio, or fraction of dollars per cookie or cookie per dollars.

12 cookies             6                    2

----------------   =    -----------   =  -------------    So this means 2 cookies per 3 dollars.

18 dollars                9                   3

Now if you increase the numerator by 9 (the numerator is cookies) and you find that there are 18 cookies, then how much money is there to pay?

This can be found by increasing the denom. by 9 as well:

3  x   9  =  27

So then the cost is 27 dollars, and that is how much you have to pay.

Answer:

2(29D-28adn-29)

Step-by-step explanation:

Answer:

Rational.

Step-by-step explanation:

Many floating point numbers are also rational numbers since they can be expressed as fractions. For example, 1.5 is rational since it can be written as 3/2, 6/4, 9/6 or another fraction or two integers. Pi (π) is irrational since it cannot be written as a fraction.

Answer:

3.7777 > 3.77 or 3.77 < 3.7777

Answer:

√113

Step-by-step explanation:

As per distance formula:

Points are:

So the distance:

Answer is √113

Answer:

√113

Step-by-step explanation:

B(3,5) , A(-4,-3)

distance between 2 points : d

d=√(x2-x1)²+(y2-y1)²

d=√(3-(-4)²+(5-(-3)²

d=√7²+8²

d=√49+64

d=√113

Answer:

11 + 5[tex]\sqrt{5}[/tex]

Step-by-step explanation:

Note that [tex]\sqrt{5}[/tex] × [tex]\sqrt{5}[/tex] = 5

Given

(3 + [tex]\sqrt{5}[/tex] )(2 + [tex]\sqrt{5}[/tex] )

Each term in the second factor is multiplied by each term in the first factor, that is

3(2 + [tex]\sqrt{5}[/tex] ) + [tex]\sqrt{5}[/tex](2 + [tex]\sqrt{5}[/tex] ) ← distribute both parenthesis

= 6 + 3[tex]\sqrt{5}[/tex] + 2[tex]\sqrt{5}[/tex] + 5 ← collect like terms

= 11 + 5[tex]\sqrt{5}[/tex] ← in the form a + b[tex]\sqrt{5}[/tex]

with a = 11 and b = 5

Answer:

Your answer would be D, the equation is a function because it is a polynomial and all polynomials are functions.

Step-by-step explanation:

I like to remember that polynomials have no negative , fraction exponents and no division. In this case everything is positive so I knew it was a polynomial , and like the answer says all polynomials are functions !

Answer: $18.76

Step-by-step explanation:

Let original cost of meal =x

According to question,

x+20%=18.96

x=18.96-20%

x=$18.76

Answer:

original cost of meal  = $15.80

Step-by-step explanation:

120% = $18.96 (divide both sides by 120)

1% = $0.158  (multiply both sides by 100)

100% = $15.80

Answer:

98 degrees

Step-by-step explanation:

The total sum of the angles of a pentagon is 540 degrees and the sum of the four given angles is 442 degrees. So, the answer is 540 - 442 = 98

Answer:

-7

Step-by-step explanation:

So we have the two functions:

[tex]f(x)=2x+7\text{ and } g(x)=-3x+5[/tex]

And we want to find f(g(4)).

So, find g(4) first:

[tex]g(x)=-3x+5\\g(4)=-3(4)+5[/tex]

Multiply:

[tex]g(4)=-12+5[/tex]

Add:

[tex]g(4)=-7[/tex]

Now, substitute:

[tex]f(g(4))=f(-7)[/tex]

Use the equation from f(x):

[tex]f(x)=2x+7\\f(-7)=2(-7)+7[/tex]

Multiply:

[tex]f(-7)=-14+7[/tex]

Add:

[tex]f(-7)=-7[/tex]

So:

[tex]f(-7)=f(g(4))=-7[/tex]

And that's our answer :)

Answer: kindly check explanation

Step-by-step explanation:

As a consumer, a number of factors play a number of factors play a major role and guides my purchasing decision. These factors include :

Employment : Being employed or self employed and being unemployed definitely plays a role in one's income level. An unemployed individual may tend to be more conservative when deciding on what or what not to purchase.

Income : Employment has grades which could be defined based on income level of workers, individuals with higher wages or salaries will tend to boast more financial strength than those with meager income.

Prices : Cost of items may be used to interpret quality product in some cases, hence some individuals may be put off by high cost associated to a product while some may be attracted to them.

Interest rate: Interest rates are often unstable and as such may guide an individual's investment plan, by holding on when interest falls and financing when it rises.

Consumer confidence : The contentment individuals derive from using a product may be nurtured through previous experience and hence either builds consumer confidence in a certain brand or a loss or decline in confidence over such product.

Answer:

I think it is A.

Step-by-step explanation:

Use the remainder theorem, which says the remainder upon dividing a polynomial [tex]p(x)[/tex] by [tex]x-c[/tex] is exactly [tex]p(c)[/tex]. In this case,

[tex]p(x)=2x^2+2x+1[/tex]

[tex]c=-1[/tex]

[tex]\implies p(c)=2(-1)^2+2(-1)+1=\boxed{1}[/tex]

Answer:

5,6

Step-by-step explanation:

Answer: -8

Explanation: It's a good idea to get into the habit of using parenthses

when substituting numbers in for variables.

Since x = -3 and y = 6, 22 - 3y + 4x is 22 - 3(6) + 4(-3).

3(6) is 18 so we have 22 - 18 + 4(-3).

4(-3) is - 12 so we have 22 - 18 + -12.

Now, 22 - 18 is 4 and 4 + -12 is -8.

Answer:

-8

Step-by-step explanation:

Subsitute the variable "y" with 6 and the variable "x" with -3. Once the variables are replaced with the right numbers, the equation should read 22- 3(6) +4(-3). Using PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction) you should do what's in the parentheses first. -3 times 6 is -18 and 4 times -3 is -12. 22-18-12= -8
