The graph represents the cost y (in dollars) to open an online gaming account and buy x games. Find the slope and the y-intercept of the line.

Answers

Answer 1

Answer:

Slope = 0.1 or 1/10

Y-int. = 15

Step-by-step explanation:

We have points (0,15), (3,45), (6,75), and (9,105).

slope is rise over run, or rise/run.

So, 9-3/105-45=6/60

now, simplify 6/60.

6/60=1/10 or 0.1

We already have the y-intercept, (0,15), because that's what intercepts the y-axis.

Answer 2

The slope of the line is 10.

The y-intercept of the line is 15.

Locate two points on the graph, choosing points whose coordinates are integers. We will use (3, 45) and (9, 105).

Starting with the point on the left, (3, 45) going from the first point to the second point, (9, 105).

The rise on the vertical leg of the triangle = (105 - 45) = 60

The run on the horizontal leg of the triangle = (9-3) = 6

Use the slope formula.

[tex]m = \frac{rise}{run}[/tex]

[tex]m=\frac{60}{6} =10[/tex]

The slope of the line is 10.

The y-intercept of a graph is the point where the graph crosses the y-axis. (Because a function must pass the vertical line test, a function can have at most one y-intercept.

the y-intercept of the line is 15.

Therefore, The slope of the line is 10 and the y-intercept is 15.

QUESTION:How many paper cups can be filled completely using all of the water from the full water cooler
ANSWER CHOICE:

216

Answers

Answer:

108

Step-by-step explanation:

find the volume of the cooler:

V=πr²h

π×6²×16= 1809.56

find the volume of the cup:

V=πr²(h/3)

π×2²×(4/3)= 16.76

divide the volume:

1809.56/16.76= 107.969

Assuming that the cooler is full to the max, and cups are filled almost to the top, the cooler contains 108 cups of water.

The quotient of a number and 6 is less than 20.

Answers

Answer:

[tex]\frac{x}{6}[/tex] < 20

Step-by-step explanation:

hope this help idrk how to explain this one lol

We want to write a math phrase into a math expression (an inequality).

The inequality will be: x/6 < 20

The phrase is:

"The quotient of a number and 6 is less than 20."

We can break the phrase to explain how to write it.

The first part:

"The quotient of a number and 6..."

is written as:

x/6

where "a number" is x.

Now the second part:

"...is less than 20"

is written as:

< 20

This means that the thing at the left is smaller than 20.

Now, the whole inequality will be:

x/6 < 20

We could simplify this to get:

x < 20×6 = 120

x < 120

5.2x-y=4.1 1.5x+y=6.7
how to solve this problem

Answers

Answer: x=1.6

y=4.2

Step-by-step explanation:

5.2x - y = 4.1

1.5x + y = 6.7

we will add both equations and you see that the y is getting cancelled

6.7x=10.8

x=10.8/6.7= 1.6

now in any equation we will replace x with 1.6

5.2(1.6)-y=4.1

8.3-y=4.1

-y= 4.1-8.3

-y=-4.2 multiply by -1

y=4.2

Answer:

x = 1.61 (Estimated)

y = 4.28 (Estimated)

Step-by-step explanation:

5.2x - y = 4.1

1.5x + y = 6.7

5.2x − y = 4.1

−y = −5.2x + 4.1

y = 5.2x − 4.1

Solve for x:

1.5x + y = 6.7

1.5x + 5.2x − 4.1 = 6.7

6.7x − 4.1 = 6.7

6.7x = 10.8

x = 1.61194

Solve for y:

y = 5.2x − 4.1

y = 5.2 × 1.61194 − 4.1

y = 4.28209

Answer:

B (130°)

Step-by-step explanation:

Because the angles are adjacent that means:

m<ADE + m<CDA = m<CDE

Using this equation, we can find what m<ADE is:

m<ADE = m<CDE - m<CDA

m<ADE = 177° - 47°

m<ADE = 130° (B)

Hope this helps :)

Answer:

Step-by-step explanation:

CDE is 177, meaning it’s not a straight line so it’s 3 degrees from a perfect line so if CDA is 47 add the 3 degrees and see if CDE was a perfect line what answer would get you 180.

A garden store sells plants in flats there are six plants in each tray each flat has six trays the garden store sold 16 flats on Saturday and 21 flats on Sunday how many plants did the garden sell in all

Answers

Answer:

1332 plants

Step-by-step explanation:

From the above question

1 tray = 6 plants

6 tray = 1 flat

Hence,

1 tray = 6 plants

6 tray = x plants

= x = 6 × 6 plants

= 36 plants

Hence, 1 flat = 36 plants

We are told: the garden store sold 16 flats on Saturday and 21 flats on Sunday how many plants did the garden sell in all

Total number of flats sold = 16 flats + 21 flats = 37 flats

That number of plants sold =

1 flats = 36 plants

37 flats = x plants

x = 37 × 36 plants

x = 1332 plants

False. They create right angles

The perimeter of the rectangle below is 65 inches.

a. What is the value of x?

b. What are the dimensions of the rectangle?

Answers

A :-) Given -
perimeter = 65 inches
Side ‘a’ = 2x
Side ‘b’ = 3 1 by 4x + 1
Solution -
Perimeter = 65
= a + b = 65
= 2x + 3 1 by 4x + 1 = 65
( 3 1 by 4 = 4 x 3 + 1 = 12 + 1 by 4
= 13 by 4 )
= 2x + 13 by 4x + 1 = 65
= 2x + 13 by 4x = 65 - 1
= 2x + 13 by 4x = 64
= 15 by 4 x = 64
= x = 64 x 4 by 15
= x = 256 by 15
= x = 17.06

.:. The value of x = 17.06.
