Answer:

y = -2

Step-by-step explanation:

This one is easy. As you may know, a axis of symmetry is the line where everything is the same on both sides of it. For this, you can use trial and error or just look at the points on either side. For y = -1, that will put the line in an awkward spot, crossing through 2 slanted lines instead of corners. For x = -1, this just cuts through the shape straight up and down and does not make the shape look equal on both sides of the line at all. Same goes for x = -2. I should probably mention, when you see a line that is described as "x = 1", it is a vertical line, because the line is constantly staying on the point x = 1, while having an infinite number of y-values. When you see "y = 1", it will be horizontal for the same reason, just flipped.

Answer:

We took $ 24 to the movies.

Step-by-step explanation:

Let total money be

On movies = Half of the money = $\frac{x}{2}$

On popcorn = $\frac{x}{4}$

on candy = $2

On soda = $3

total money spent = $\frac{x}{2}$ + $\frac{x}{4}$ + 2+3+1

x = $\frac{x}{2}$ + $\frac{x}{4}$ + 2+3+1

x- $\frac{x}{2}$ - $\frac{x}{4}$ = 6

$\frac{x}{1}$ - $\frac{x}{2}$ - $\frac{x}{4}$ =6

$\frac{4x-2x-x}{4} = 6\\ \frac{x}{4} =6\\x =24$

The cost of renting a fishing boat is $25 per hour for the first 7 hours, $10 per hour for the next 10 hours, and $5 per hour fo

yKpoI14uk [10]

Answer: $340

Step-by-step explanation:

To identify the cost of renting the boat for 30 hours, breakdown the 30hours into specific renting hours

i.e 30 hours = (7 hours + 10 hours + 13 hours)

Then calculate each of the renting cost based on the hour breakdown given above

- Since the Cost of renting a fishing boat is $25 per hour for the first 7 hours, then (25 x 7 hours = $175)

- For the $10 per hour for the next 10 hours, then (10 x 10 hours = $100)

- and for $5 per hour for any additional hours. (5 x 13 additional hours = $65)

Now, sum up all of the cost of the hourly breakdown

i.e 30 hours = (7 hours + 10 hours + 13 hours)

= $175 + $100 + $65

= $340

Thus, the cost of renting the boat for 30 hours is $340

Answer:

Step-by-step explanation:

lets find median 2, 4, 4, 5, 6, 8, 9, 10, 10, 13, 17

now lets find the lower quartile median and upper quartile median

we don't include the median in the count, only use it to divide the data into the two parts,

2, 4, 4, 5, 6, 8, 9, 10, 10, 13, 17

so lower quartile median is 4,

2, 4, 4, 5, 6, 8, 9, 10, 10, 13, 17

while upper quartile median is 10

the box represents the range between the upper quartile median and lower quartile median, thus is should go from 4 to 10 with the middle line, representing the median at 8,

the whiskers represent the whole data range

thus, the answer is C
