Answer:

$3.4875

Step-by-step explanation:

AS the ride is completed and according the rule the person have to give a tip on the total taxi ride

according to the given

tip given 15%

Total ride cost = $23.25

To find is the total tip given in dollars

Solution:

Total tip in dollars = 15 % of total ride cost

Putting the values of the given

Total tip in dollars = 15 % of 23.25

it can be written as

                             = [tex]\frac{15*23.25}{100}[/tex]

                              =[tex]\frac{348.75}{100}[/tex]

                               =$ 3.4875

So the total tip would be $3.4875

Answer:

3.50 cent

Step-by-step explanation:

I take 10% and 20% of the number. For this ride, that would be about $2.33 and 4.66.

The length of {MZ} will be equivalent to -

MZ = 4 - 2x.

Given is that M is the midpoint of YZ. Also, it is given that YM = x + 3, and YZ = 3x - 1.

We can write -

YM + MZ = YZ

(x + 3) + MZ = (3x - 1)

MZ = (x + 3) - (3x - 1)

MZ = x + 3 - 3x + 1

MZ = 4 - 2x

Therefore, the length of {MZ} will be equivalent to -

MZ = 4 - 2x.

Answer:

Option C -M'K' is the same length as MK

Step-by-step explanation:

Given : Line segment MK has endpoints at (2, 3) and (5,4)

               M'K' is the reflection of MK over the y-axis

By definition of reflection: reflection of point (x,y) across the the y-axis is the point (-x,y)

which implies M'K' has end points (-2,3) and (-5,4)

Now, we find the length of MK

let [tex](x_1,y_1)=(2,3)\\\\(x_2,y_2)=(5,4)[/tex]

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

⇒ [tex]d=\sqrt{(2-5)^2+(4-3)^2}[/tex]

⇒[tex]d=\sqrt{9+1}[/tex]

⇒[tex]d=\sqrt{10}[/tex]   ....(1)

Now, we find the length of M'K'

let [tex](x_1^{'},y_1^{'})=(-2,3)\\\\(x_2^{'},y_2^{'})=(-5,4)[/tex]

[tex]d^{'}=\sqrt{(x_2^{'}-x_1^{'})^2+(y_2^{'}-y_1^{'})^2}[/tex]

⇒ [tex]d^{'}=\sqrt{(-2+5)^2+(3-4)^2}[/tex]

⇒[tex]d^{'}=\sqrt{9+1}[/tex]

⇒[tex]d^{'}=\sqrt{10}[/tex] .....(2)

from (1) and (2) we simply show that the length of MK and M'K' is equal

we can also refer the figure attached for reflection of MK and M'K'

therefore, Option C is correct

Answer:

M'K' is the same length as MK.

Answer:

Step-by-step explanation:

Alright, lets get started.

Suppose one side of the kite is x

One side of a kite is 5 cm less than 2 times the length of another.

So, another side of the kite will be = [tex]2x-5[/tex]

So, the all 4 sides of the kite will be x, x , 2x-5 and 2x-5

The perimeter of the kite will be = [tex]x+x+2x-5+2x-5=6x-10[/tex]

As per given in question, perimeter is 14, so

[tex]6x-10=14[/tex]

Adding 10 in both sides

[tex]6x=24[/tex]

Dividing 6 in both sides

[tex]x=4[/tex]

So, another side is [tex]2*4-5=3[/tex]

So, the sides are 4 cms and 3 cms   :   Answer D

Hope it will help :)

Answer:

D) 4 cm, 3 cm  

Step-by-step explanation:  

Since we know that kite is made of two sets of equal sides.

Let x be the length of one of equal sides and y be length of another side of equal sides.      

We have been given that one side of a kite is 5 cm less than 2 times the length of another. We can represent this information as:

[tex]x+5=2y...(1)[/tex]

We are also told that the perimeter is 14 cm. We can represent this information as:

[tex]2(x+y)=14...(2)[/tex]

From equation (1) we will get,

[tex]x=2y-5[/tex]

Substituting this value in equation (2) we will get,

[tex]2(2y-5+y)=14[/tex]

[tex]2(3y-5)=14[/tex]

[tex]6y-10=14[/tex]

[tex]6y-10+10=14+10[/tex]

[tex]6y=24[/tex]

[tex]y=\frac{24}{6}[/tex]

[tex]y=4[/tex]

Therefore, length of one side of kite is 4 cm.  

Upon substituting y=4 in equation (1) we will get,

[tex]x+5=2*4[/tex]

[tex]x+5=8[/tex]

[tex]x+5-5=8-5[/tex]

[tex]x=3[/tex]

Therefore, the length of another side of kite is 3 cm and option D is the correct choice.

Answer:

m ≤ 27  or m > 11

m is all real number since we have the or

Step-by-step explanation:

m − 11 ≤ 16 or 15 − 2m < −7

Lets solve the one on the left first

m − 11 ≤ 16

Add 11 to each side

m-11+11 ≤ 16 +11

m ≤ 27

Now lets solve the one on the right

15 − 2m < −7

Subtract 15 from each side

15 −15- 2m < −7 -15

-2m < -22

Divide by -2, remembering to flip the inequality

-2m/-2 > -22/-2

m > 11

Answer:

Final answer is y=3x-2.

Step-by-step explanation:

We have been given a graph and using that graph we need to find the equation of line.

Equation of line is given by formula y=mx+b

Where b is the y-intercept.

We see that graph crosses y-axis at (0,-2) so that means b=-2

Now plug b=-2 into formula y=mx+b. We get:

y=mx-2 ...(i)

Now find any point from the graph say (1,1) and plug into (i) to find value of slope m

1=m*1-2

1=m-2

1+2=m

3=m

Now plug m=3 into (i). We get:

y=3x-2

Hence final answer is y=3x-2.

Answer:

2.  x=-2  y= 2

3. x=3 y=0

Step-by-step explanation:

-2x - 3 y = -2

y = 2x + 6

The first step is to get x and y on the same side

Take the second equation and subtract 2x from each side

-2x+ y = 2x-2x + 6

-2x+y = 6

Multiply this by -1

-1(-2x+y) =-1*6

2x -y =-6

Add this to the first equation  to eliminate x

-2x - 3 y = -2

2x -y =-6

--------------------

-4y = -8

Divide by -4

-4y/-4 = -8/-4

y =2

Now we need to find x

y = 2x + 6

Substituting in y=2

2 = 2x+6

Subtract 6 from each side

2-6 = 2x+6-6

-4 = 2x

Divide by 2

-4/2 = 2x/2

-2 =x

3) -x - 18 y = -3

7x - 9 y = 21

We will eliminate by by multiplying the second equation by -2

-2(7x - 9 y) = -2*21

-14x + 18y = -42

Now we will add this to the first equation

-x - 18 y = -3

-14x + 18y = -42

-------------------------

-15x    = -45

Divide by -15

-15x/-15 = -45/-15

x =3

We still need to solve for y

-x -18y = -3

Substituting in x =3

-3 -18y = -3

Add 3 to each side

-3+3 -18y =-3+3

-18y =0

Divide by -18

y= 0

Lets multiply the numerator

(2+3i) ( 4-3i)

8 +12i -6i - 9i^2

Remember i^2 = -1

8 +6i -9(-1)

17 +6i

Lets multiply the denominator

(4+3i) ( 4-3i)

4*4 +4*3i -3i*4 - 3i*3i =

16 +12i -12i - 9i^2

Remember i^2 = -1

Answer:

6 miles

Step-by-step explanation:

AS Mike took the taxi from his home to airport and covered a distance

Initial fee of the ride was $ 6 which is fixed

Now with each mile he has to pay $3

Total he paid = $ 24

Now we have to find the total no of miles traveled  by Mike

The tip given is 0

Now from the given we can make an equation

Initial fee + 3 * miles traveled =  total Paid

Let total no of miles traveled are x

Putting all the values in the given equation

6 + 3 * x = 24

6 + 3x = 24

3x = 24-6

3x = 18

Dividing both sides by 3

x = 18 /3

x =6 miles

So the total miles traveled by him is 6 miles

The equation is $6 + $3 *m = $24, where m represents the number of miles traveled. Solving this, Mike traveled 6 miles.

The student's question concerns calculating the distance Mike traveled by taxi, given the initial fee and the per mile charge, as well as the total fare. To solve this, we can set up a simple algebraic equation. The initial fee is $6, and the charge per mile is $3. Since the total fare was $24, our equation becomes:

Initial fee + (charge per mile * number of miles) = Total fare

$6 + $3 * m = $24

Where m represents the number of miles Mike traveled. We will solve for m to find the distance Mike traveled

Thus, Mike traveled 6 miles by taxi on this ride.

Answer:

The answer is 17 items in 5 groups.

Step-by-step explanation:

If we have 20 pencils + 25 erasers + 40 paper clips; that´s a total of 85 items.

Then we just divide all the items into 5 groups so we can have the same amount of items in each group.

85 items  ÷ 5 groups = 17 items each.

17 x 5 = 85.

Answer:

This system of linear equations represents parallel lines.

The system of equation 1 and the equation 20y = 12x + 88 represents coincidental  lines

Step-by-step explanation:

-3x + 5y = 22 (equation 1)

Lets solve the equation for y

Add 3x on both sides

5y= 3x+22

Now divide by 5 on both sides

[tex]y=\frac{3x}{5}+ \frac{22}{5}[/tex]

Slope of equation 1 is [tex]\frac{3}{5}[/tex]

20y − 11 = 12x (equation 2)

solve for y

Add 11 on both sides

20y = 12x + 11

Divide by 20 on both sides

[tex]y=\frac{12x}{20}+ \frac{11}{20}[/tex]

simplify the fraction

[tex]y=\frac{3x}{5}+ \frac{11}{20}[/tex]

Slope of equation 2 is [tex]\frac{3}{5}[/tex]

Slope of equation 1  and equation 2  are same , so the lines are parallel

This system of linear equations represents parallel lines.

-3x + 5y = 22 (equation 1) and 20y = 12x + 88

Solve both equations for y

-3x + 5y = 22 (equation 1)

[tex]y=\frac{3x}{5}+ \frac{22}{5}[/tex]

Slope of equation 1 is [tex]\frac{3}{5}[/tex] and y intercept is 22/5

20y = 12x + 88

Divide by 20 on both sides and simplify the fraction

[tex]y=\frac{3x}{5}+ \frac{22}{5}[/tex]

Slope of 20y=12x+88 is [tex]\frac{3}{5}[/tex] and y intercept is 22/5

Slope and y intercepts are same so the lines are coincidental

The system of equation 1 and the equation 20y = 12x + 88 represents coincidental  lines

Answer:

[tex]y=-\frac{7}{18}x^2+\frac{41}{18}x+\frac{64}{9}[/tex]

Step-by-step explanation:

We need to write a quadratic equation so we can use standard quadratic equation:

[tex]y=ax^2+bx+c[/tex]

Plug the given points to get three equations.

for (7,4), we plug x=7 and y=4

[tex]4=a(7)^2+b(7)+c[/tex]

[tex]4=49a+7b+c[/tex] ...(i)

similarly using other two points, we get:

[tex]1=4a-2b+c[/tex] ...(ii)

[tex]9=a+b+c[/tex] ...(iii)

Now we solve those three equations by any method like substitution, or matrices or by any method and get:

[tex]a=-\frac{7}{18},\ b=\frac{41}{18},\ c=\frac{64}{9}[/tex]

Now plug these values into [tex]y=ax^2+bx+c[/tex], we get final equation as:

[tex]y=-\frac{7}{18}x^2+\frac{41}{18}x+\frac{64}{9}[/tex]
