The water level of a river was measured each day during a two-week period. The graph models the linear relationship between the water level of the river in feet and the number of days the water level was measured. Which statement best describes the y-intercept of the graph?

Answers

Answer 1

Answer:

Step-by-step explanation:

Answer 2

The y-intercept of a graph is the point where the graph touches the y-axis.

The best describes the y-intercept of the graph is (a) the initial water level of the river is 16 ft

From the attached graph, we observe that the graph crosses the y-axis at y = 16

This value represents the initial value of the graph.

In other words, the initial water level of the river

So, the y-intercept means that:

The initial water level of the river is 16 ft

Hence, the true statement is (a)

I really need help with these questions 5. Wesley subscribes to telecommunications company's movie package The plan includes a basic monthly charge of $40 and an additional charge of $ 1.50 for every movie ordered. Another telecommunications company's movie package deal is a monthly charge of $ 30 and a charge of $2 per movie ordered Wesley better off to stay with his current deal? A.) Write an equation and solve it to determine how many movies Wesley would need to rent for the price to be the same at each company. B.) How much would it cost? Show your work

Answers

Answer:

20 movies ; $70

Step-by-step explanation:

Company 1:

Monthly charge = $40 ; additional = 1.5 per movie

Let number of movies = x ; t = cost

Equation 1:

y = 40 + 1.5x

Company 2:

Monthly charge = $30

Additional = $2 per movie

Equation 2:

y = 30 + 2x

1) for equation 1 = equation 2

40 + 1.5x = 30 + 2x

40 - 30 = 2x - 1.5x

10 = 0.5x

x = 10/0.5

x = 20

Hence, 20 movies

B.)

y = 30 + 2x

y = 30 + 2(20)

y = 30 + 40

y = $70

Answers

False. You need to graphically turn the triangle and see if it matches. It’s a trick question, the legs don’t match. They switched the position of the 5 on each triangle and the legs are 100% not equal (30-60-90 triangle).

Note: if the question was changed to 45 degree angle (45-45-90) instead of the famous (30-60-90) then they would be congruent because both legs of each triangle would be 5. In other words the 45 degrees tells us the legs are equal on every triangle but the 30-60-90 triangle tells us 100% the legs must be different.

f(x)=-2x+3
g(x)=3x+3
find f(1-x) + g(1-x)

Answers

Answer:

-5x + 11

Step-by-step explanation:

All you're doing is substituting.

f(x)=-2x+3

f(1-x) = 2(1-x)+3

= 2 - 2x +3

= -2x + 5

g(x)=3x+3

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

= 3 - 3x + 3

= -3x + 6

Now add them together and combine like terms:

f(1-x) + g(1-x)

-2x + 5 + -3x + 6

= -5x + 11

Adsilla and Carlos volunteer to fill gift boxes for soldiers serving overseas. Both work at a constant rate. They work together for 4 hours and fill 108 boxes. Adsila fills 11 boxes every hour. How many boxes does carlos fill every hour?

Answers

Answer:

[tex]Carlos = 16[/tex] per hour

Step-by-step explanation:

Given

[tex]Total = 108\ boxes[/tex]

[tex]Hours = 4[/tex]

[tex]Adsila = 11\ boxes\ per\ hour[/tex]

Required

Determine the unit rate of Carlos

First, we need to calculate the total boxes filled by Adsila.

If Adsila gets 11 in 1 hour.

Then Adsila get 4 * 11 in 4 hours

[tex]4 * 11 = 44\ boxes[/tex]

Next, we calculate number of boxes left.

[tex]Left = 108 - 44[/tex]

[tex]Left = 64[/tex]

This is yhe number of boxes filled by Carlos.

Recall that they worked for 4 hours each.

Hence:

[tex]Carlos = \frac{64}{4}[/tex]

[tex]Carlos = 16[/tex]
