Victoria wants to figure out if she can run faster thar. an elephant. She reads that an elephant can run 100
yards in 20 seconds. She knows she can run 60 feet in
10 seconds. Victoria says, "Since to = 6 and 20 = 5,
my speed is faster than an elephant's!โ€ Does her
statement make sense? Explain why or why not.

The points are (1, -11) and (17, -11).

Step-by-step explanation:

The distance between points (x1, y1) and (x2, y2) is

d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

We have values for x1, y1, and y2. We leave x for x2, and we solve for x.

17 = \sqrt{(x - 9)^2 + (-11 - 4)^2}

Square both sides.

289 = (x - 9)^2 + (-11 - 4)^2

289 = x^2 - 18x + 81 + 225

x^2 - 18x + 17 = 0

(x - 1)(x - 17) = 0 [/tex}[tex] x - 1 = 0 ย  or ย  x - 17 = 0

x = 1 or x = 17

The points are (1, -11) and (17, -11).
