Answer: (0, 0) (1, 3) (2, 6)

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

Choose a number for Xena, then multiply that number by 3 to calculate what Yolie would say:

$\begin {array}{c|l||c}\underline{Xena}&\underline{\quad Yolie\quad}&\underline{Xena, Yolie}\\ 0&3\times 0=0&(0,0)\\1&3\times 1=3&(1,3)\\2&3\times 2=6&(2,6)\\\end{array}$

15 POINTS!!!! BRAINLIEST FOR THE FIRST ANSWER!!! Solve 3-x/2≤18

Bumek [7]

Answer:

$x\geq -30$

Step-by-step explanation:

Work to isolate x on one side of the inequality:

$3-\frac{x}{2} \leq 18\\3-18\leq \frac{x}{2} \\-15\leq \frac{x}{2}\\-30 \leq x$

Therefore the answer is all x values larger than or equal to -30

$x\geq -30$

A taut string of length 10 inches is plucked at the center. The vibration travels along the string at a constant rate of c inche

Mademuasel [1]

Answer:

The correct option is

$A. \ \dfrac{1}{c} \times \left | x - 5 \right | = 0.3$

Step-by-step explanation:

The parameters given are;

The length of the string = 10 inches

The speed or rate of travel of the wave = c inches per millisecond

The position on the string from the left-most end = x

The time duration of motion of the vibration to reach x= 0.3 milliseconds

The distance covered = Speed × Time = c×0.3

Given that the string is plucked at the middle, with the vibration travelling in both directions, the point after 0.3 millisecond is x where we have;

The location on the string where it is plucked = center of the string = 10/2 = 5 inches

Distance from point of the string being plucked (the center of the string) to the left-most end = 5 inches

Therefore, on the left side of the center of the string we have;

The distance from the location of the vibration x (measured from the left most end) to the center of the string = 5 - x = -(x -5)

On the right side of the center, the distance from x is -(5 - x) = x - 5

Therefore, the the equation that can be used to find the location of the vibration after 0.3 milliseconds is $\dfrac{1}{c} \times \left | x - 5 \right | = 0.3$ or $\left | x - 5 \right | = 0.3 \times c$ which gives the correct option as A

A new factory is growing fast and hiring a lot of new workers. Every week, the total number of workers doubles in size. If it ta

MAXImum [283]

We know that the number of workers doubles every week.

This implies that the number of workers of the previous week is exactly half of the current one's.

So, it took 11 weeks for the factory to be at half capacity.

A rancher wishes to enclose a rectangular pasture with 320 feet of fencing. the fencing will be used on three sides of the pastu

bulgar [2K]

Let each side perpendicular to the wall be x
The parallel to the wall will be 320-2x
the area will be:
A(x)=x(320-2x)
A(x)=320x-2x^2
This is a quadratic with a =-2 and b=320

Maximum area will occur where x=-b/2a
=-320/(-2*2)
=80 ft
thus the width will be 80 ft and the length will be:
length=320-2*80=160 ft

Given f(x) = 3x-1 and g(x) - 2x-3, for which value of x does g(x) = f(2)?

sineoko [7]

Answer:

$x = 4$

Step-by-step explanation:

$f(2) = 3 \times 2 - 1 = 5 \\ g(x) = 5\Leftrightarrow 2x - 3 = 5\Leftrightarrow 2x = 8\Leftrightarrow x = 4$
