Refraction trust me I am in high school biology
Step-by-step explanation:
Ok this inequality tells you the number of devices you can have before the new plan costs more than the old plan. The new plan expression is $4.50x + $94m = y ( total cost). The old plan is $175m = y (total cost). You can see m (number of months) in both equations, you don't need it this time since we're going to to compare both to one month. Since they're both equal to y you can make them equal to each other. $4.50x + $94 = $175. Now you want to figure when the new plan is less than the old plan you switch the equal sign for a less than sign. $4.50x + $94 < $175; this will help you find the inequality you want. From there just use algebraic steps to find that x has to less than 18 or
x < 18.
The required set of coordinates with the match is shown.
Distance between points can be evaluated from the distance formula,
(3, 4) and (2, 1)
= √[(3-2)² + (4-1)²]
= √ 10
Similarly,
The points whose distance between them is √10 are,
(3, 4) and (2, 1)
(-2, 3) and (1, 2)
(-4, -2) and (-3, 1)
The points whose distance between them is √29 are,
(3, 7) and (5, 2)
(5,-2) and (3, 3)
(4, -1) and (-1, 1)
Thus, the required set of coordinates with the match is shown.

Answer:
f(x) = 3x + 2
x = 3f-1(x) + 2
x - 2 = 3f-1(x)
(x - 2)/3 = f-1(x)
(14 - 2)/3 = f-1(14)
12/3 = f-1(14)
4 = f-1(14)
f(f-1(14)) = f(4)
f(4) = 3(4) + 2
f(4) = 12 + 2
f(4) = 14
A function and its inverse are inverse operations, like addition and subtraction. They undo each other.
f(f-1(x) = x
