Step-by-step explanation:
(x, y) = (-20, 7), (-5, -2), (0, 3), (15, -4), (30, 5)
You want 1/5x to match the x-value in the given table. To make that happen, multiply the given x by 5.
Example: when (1/5x) = -4, f(1/5x) = 7, so x = -4·5 = -20 for y = 7.
The transformation f(1/5x) is a horizontal expansion by a factor of 5, so each point of f(x) is now 5 times farther from the y-axis than it was.

Answer: x = 20
Step-by-step explanation:
We can use the pythagorean theorem:
x^2 + 15^2 = 25^2
x^2 + 225 = 625
We can subtract 225 from both sides:
x^2 = 400
We can take the square root of both sides:
x = 20.
Step-by-step explanation:
well, there are 4× 1-9 meaning 36 cards
36/52
divide both sides by 4
9/13
