What you have so far is correct.

Problem 7 is a function because none of the x values repeat. Each x input goes to exactly one y output. The y values can repeat. If the y values repeat, then we don't have a one-to-one function.

In contrast, problem 8 is not a function. We have x = 1 go to y = 8 and y = 6 at the same time. This is one example showing we don't have one output for a given input.

What is the distance between (6, 1) and (1, -9)?

AVprozaik [17]

Answer: √15 units

Step-by-step explanation:

Let (6,1) be (x^1,y^1) and (1,-9) be (x^2,y^2) .

As we know ,

Distance(D) = √(x^1-x^2) +(y^1-y^2)

Now,

D= √(x^1-x^2) +(y^1-y^2)

= √(6-1) +(1+9)

= √5+10

= √15 units

: Therefore the distance between (6,1) and (1,-9) is √15 units.

Shanna is planning a trip from Dallas, Texas, to San Diego, California. She knows that the distance she will travel is

enot [183]

Answer:

4.67 inches

Step-by-step explanation:

Shanna is planning a trip from Dallas, Texas, to San Diego, California.

She will travel about = 1,400 miles

The scale of a map is 300 miles = 1 inches

The trip of 1,400 miles = $\frac{1400}{300}$

= 4.66666 inches ≈ 4.67 inches

Her trip is 4.67 inches far on the map.

11111nata11111 [884]

The 9 is in the tenths place so it should be 9x1/10. Meaning it would be 100+3x1+9x1/10+3x1,000
