6 0

Answer: The second endpoint is (2,6)

Step-by-step explanation:

$\frac{-6 +x}{2}$ = -2 solve for x

-6 +x = -4

+6 +6

x= 2

$\frac{-6+y}{2} = 0$

-6 + y = 0

+6 +6

y= 6

Sam and Bobby want to know who cycled faster. The table shows the total miles Sam traveled over time. The graph shows the same r

tigry1 [53]

Answer:

<h2>Sam cycled fast, at a rate of 10 miles per hour.</h2>

Step-by-step explanation:

To solve this problem we have to find the slope of each case. The definition of a slope is:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\$

Where $(x_{1};y_{1})$ is the first point, and $(x_{2};y_{2})$ is the second point.

Let's find each slope.

<h3>Sam.</h3>

Let's use the points $(2;20)$ and $(5;50)$

Applying the definition of the slope, we have:

$m_{sam} =\frac{50-20}{5-2}=\frac{30 \ miles}{3 \ hour}=10 \ miles/hour$

This relation means that Sam cycled 10 miles per hour.

<h3>Bobby.</h3>

Let's use the points $(2;18)$ and $(6;54)$

$m=\frac{54-18}{6-2}=\frac{36 \ miles}{4 \ hour}=9 \ miles/hour$

Bobby cycled 9 miles per hour.

Therefore, according to these ratios, Sam cycled fast, at a rate of 10 miles per hour.

Adonis created a rectangular play area for his dog in his backyard. The length of the long side was 10ft and the length of the s

Drupady [299]

Answer:

The perimeter of the dog's play area is 30 ft

Step-by-step explanation:

Rectangle:

The opposite sides are congruent.
The opposite angles are congruent.
The sum of all four angles of a rectangle is 360°.
The sum of two adjacent angles of a rectangle is 180°.
The diagonals bisect each other.
The perimeter of a rectangle is = 2(Length+width)
The area of a rectangle is = Length × width

Given that,

The length of the long side of the dog's play area was = 10 ft.

So, Length of dog's play area is = 10 ft.

The length of the short side of the dog's play area was = 5 ft.

So, width of dog's play area is = 5 ft.

It is a rectangular plot.

So, the perimeter of the dog's play area is =2(Length+width)

=2(10+5) ft

=2(15) ft

=30 ft

Diego has two jobs. He works 3 hours at the library each day, making $8 per hour. In addition, he works at a coffee shop, making

Zepler [3.9K]

Answer:

D. l = 3 || 4 < c < y || 8l + 7.5c ≥ 70

Step-by-step explanation:

<h3>Work at library</h3>

Time = 3 hours ⇒ l = 3
Payment = $8 per hour
Total payment = 8l

<h3>Work at coffee shop</h3>

Time = between 4 and 7 hours ⇒ 4 < c < 7
Payment = $7.5 per hour
Total payment = 7.5c

Target income = at least $70 daily

<u>So the system as per above parameters:</u>

l = 3
4 < c < y
8l + 7.5c ≥ 70

Correct option is D
