Given the domain {-2,2,4} what is the range for the relation 9x+3y=6
OleMash [197]

Answer:

{8,-4,-10}

Step-by-step explanation:

re arrange relation, im going to assume x is the domain input and y is the range.

-3x+2=y

plug in every element of the set x to get the range set y

-3(-2)+2=y

y=8

-3(2)+2=y

y=-4

-3(4)+2=y

y=-10

so the range is {8,-4,-10}

If two objects travel through space along two different curves, it’s often important to know whether they will collide. (Will a
galina1969 [7]

Answer:

<em>Both objects collide at t=3 in the point  <9,9,9></em>

Step-by-step explanation:

<em>Collision Of Moving Objects </em>

Two objects can describe different trajectories in the space. Those trajectories can intersect in one or more points but it doesn't mean they collide. Collision occurs if they are in the same position at the same time. If we know the positions as a function of time of each object, we could try so find if, for a given time, they are in the same position.

The positions of two object are given as

r1(t)=

r2(t)=

Let's find out if there is at least one value of t that makes both positions to be the same. We can try by equating one of the three coordinates and testing if the value of t make both have the same x,y,z coordinate. Let's try equating the x-components of both

t^2=4t-3

Rearranging

t^2-4t+3=0

Factoring

(t-1)(t-3)=0

We found two solutions

t=1,\ t=3

for t=1 the x-coordinates are

x1=t^2=1

x2=4t-3=1

For t=3

x1=t^2=9

x2=4t-3=9

Now we'll test both values in the y-coordinates

y1=7t-12

y2=t^2

For t=1

y1=-5

y2=1

Thus they don't collide at t=1. Let's try t=3

y1=7(3)-12=9

y2=3^2=9

Now let's try the z-coordinate for t=3

z1=t^2=9

z2=5t-6=9

Since the three coordinates match, we can say both objects collide at t=3 in the point  <9,9,9>

Solve for x: the quantity of x plus 4 over 3 = 2.<br> (x+4)<br> ------- = 12<br> 3
vaieri [72.5K]
(x + 4) / 3 = 12.....multiply both sides by 3, cancelling the 3 on the left side
x + 4 = 12 * 3
x + 4 = 36
x = 36 - 4
x = 32

Negative one over two equals negative five over eighteen h
love history [14]

Answer:

the answer is h = 5 / 9.

Step-by-step explanation:

Given is "negative one over two equals negative five over eighteen h"

It means -1 / 2 = -5 / 18h

Using cross multiplication method,

-1 * 18h = -5 * 2

-18h = -10

Cancelling negative signs from both sides,

18h = 10

Dividing both sides by 18,

h = 10 / 18

h = 5/ 9

Hence, the answer is h = 5 / 9.
