Answer:

All except the 3rd one {(12, 12), (12, 13), (12, 14)} are functions

Step-by-step explanation:

In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y.

This means that as long as some X does not give different Y values it is a function.

<h2>Solving Inequalities</h2><h3>Answer:</h3>

$(-\infty,-8]$

<h3>Step-by-step explanation:</h3>

$-2x +7 \geqslant 23 \\ -2x +7 -7 \geqslant 23 -7 \\ -2x \geqslant 16 \\ \frac{-2x}{-2} \leqslant \frac{16}{-2} \\ x \leqslant -8$

The values of $x$ has to be less than or equal to $8$ so $x \in (-\infty,-8]$

The locations, given in polar coordinates, for two ships are (8 mi, 63º) and (8 mi, 123º). Find the distance between the two shi

PolarNik [594]

The arrangement forms an isosceles triangle with equal legs of 8 mi. The angle between the legs is,

123-63 = 60°. Therefore, the other two angles ares:

Angles = (180-60)/2 = 120/2 = 60°

It can therefore be noted that all angles are equal and thus the resulting triangle is actual an equilateral triangle and thus all the sides are equal.

It can be concluded that the ships are 8 miles apart.

Answer: The 12th term is 46x -25

Step-by-step explanation:

It is increasing by 4x and decreasing by 3 through each term, this represents the d. a1 has already been identified as 2x +8, so you just have to write down the formula and the solve form there by plugging in the 12 in (n-1) to find the answer.
