The graph below represents the price of sending picture messages using the services of a phone company. What is the constant of proportionality?


10
11
21
22

Answer:

x =30

Step-by-step explanation:

4x + 40 = 6x-20 (set them equals)

40= 6x-  20-4x

40+20=2x

2x=60

divide by 2

x=30

Answer:

the answer is x=7

Step-by-step explanation:

Answer:

3.4 or 3 and 2/5

Step-by-step explanation:

Answer:

The answer is $180

Step-by-step explanation:

10% = 0.10

.10 x 1800 = 180

Answer:

cost price ( cp) =$ 1800

loss = 10%

selling price ( sp) = ?

we know,

sp= cp - loss percent of cp

= 1800- 10/100 × 1800

= 1800 - 0.1× 1800

= 1800-180

=$1620

: . $1620 is the selling price of an article.

Step-by-step explanation:

y=2x-3

Answer:

y=2x-3

Step-by-step explanation:

figure out the slope with the points (2,1) and (4,5) to get the slope of 2 meaning that you already have this much of the equation y=2x than figure out what you would need to make those points true so y=2x-3

Answer:

About 38 dollars

Step-by-step explanation:

If there is a 20 percent tip ten it would be 1/5 of the amount. Then the answer would be 38.

Answer:

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 6

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

- 11 - (- 17) = - 5 - (- 11) = 1 - (- 5) = 6

A recursive rule allows a term to be found by adding d to the previous term, thus

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 6 with a₁ = - 17

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

Given expression:

       log(5x + 20) = 2

From the given expression, we are to find x;

   Using the rule of logarithm, we can solve this problem;

             logₐb = C

                    b  = Cᵃ

So;

            log(5x + 20) = 2

  this is to base 10;

                    5x + 20 = 10²

                    5x  = 100 - 20

                    5x  = 80

                      x  = 16

Answer:

16 was right

Answer:

-28

Step-by-step explanation:

h(4)=-2(4)^2+4

-32+4=-28

Answer: 35.4 feet.

Step-by-step explanation:

Given data:

Height of the roof = 24 feet

Height of the ladder = 26 foot

Solution:

c^2 = a^2 + b^2

a = 24

b = 26

c^2 = 24^2 + 26^2

c = √576 + 676

c = √1252

c = 35.4 feet

The foot of the ladder is 35.4 foot away from the top of the ladder.

Answer:

The distance between the base of the ladder and the building is 10 ft

Step-by-step explanation:

Here, we want to calculate the distance between the foot of the ladder and the building

To get this, we need to have a pictorial representation. Please check the attachment for this

From the pictorial representation, we can see a right angled triangle with a hypotenuse of 26 feet and the other side being 24 feet. We now need to get the third side of this triangle which represents the distance we want.

Mathematically, we can calculate the distance using Pythagoras’ theorem which states that the square of the length of the hypotenuse is equal the sum of the squares of the two other sides of the triangle.

Let the distance we are looking for be D

26^2 = 24^2 + D^2

D^2 = 26^2 - 24^2

D^2 = 100

D^2 = 10^2

D = 10 feet

Answer:

its B

it's quite simple actually. It's so simple I don't know how to explain.

Answer:

the correct answer would be 13.75

Answer:

75 degrees

Step-by-step explanation:

Straight angles are 180, so since we already know one side (105 degrees). This means that 105+x=180

If you solve it you get 75

Answer:

We have been given that the upstream speed is  and the down stream speed is .

Let the fisherman traveled a distance of x miles.

The total time of the trip is 6 hours.

Relations between speed (s), time (t) and distance (d) is  

Hence,  

Time upstream +  time downstream = 6

lcm = 10

=>  

Cross multiplying,  

x = 20 miles .. Answer.

Step-by-step explanation:

The correct answer would be; 20 miles.

Step-by-step explanation:

All you have to do is plot these points on a graph. Then make a straight line through them.

The y-intercept is the point of the line that passes through y, the vertical line.

The example shows that the y-inercept is (0, 3)
