Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point A(-2, 5)

Point B(5, 5)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [DF]: $\displaystyle d = \sqrt{(5--2)^2+(5-5)^2}$
(Parenthesis) Simplify: $\displaystyle d = \sqrt{(5+2)^2+(5-5)^2}$
(Parenthesis) Add/Subtract: $\displaystyle d = \sqrt{(7)^2+(0)^2}$
[√Radical] Exponent: $\displaystyle d = \sqrt{(7)^2}$
[√Radical] Evaluate: $\displaystyle d = 7$

Tickets for a carnival cost $8 for children 12 and under and $12 for anyone over the age of 12. The carnival sold 233 tickets an

jenyasd209 [6]

Answer:

They sold 160 children's tickets.

Step-by-step explanation:

With the information provided, yoou can write the following equations:

x+y=233 (1)

8x+12y=2,156 (2), where:

x is the number of tickets for children 12 and under

y is the number of tickets for anyone over the age of 12

Now, you can solve for x in (1):

x=233-y (3)

Then, you have to replace (3) in (2) and solve for y:

8(233-y)+12y=2,156

1,864-8y+12y=2,156

4y=2,156-1,864

4y=292

y=292/4

y=73

Finally, you can replace the value of y in (3) to find x:

x=233-73

x=160

According to this, the answer is that they sold 160 children's tickets.

Combine like terms to simplify the expression: -5.55-8.55c+4.35c

Lera25 [3.4K]

Answer:

-5.55 - 4.2c

Step-by-step explanation:

-5.55 - 8.55c + 4.35c

'-8.55c' and '4.35c' are like terms because of them containing the same variable of 'c'.

Combine:

-5.55 - 8.55c + 4.35c

-8.55 + 4.35 = -4.2

-5.55 - 4.2c

Hope this helps.

Charlotte is running at a rate of 9 km/h what is charlottes speed in m/s

Harrizon [31]

Answer: The conversion factor between km and m is 1 km = 1000 m, and between hr and seconds, it is 1 hr = 3600 s. Let's first convert 9 km/hr to m/hr.

9 km/hr x (1000 m / 1 km) = 9000 m/hr

Then use the 2nd conversion factor to convert hr to seconds.

9000 m/hr x (1 hr / 3600 s) = 9000 / 3600 m/s = 5/2 m/s
