The only ordered pair that is a solution to the given system of equations is (-2, -6)

<h3>System of Linear Equations </h3>

From the question, we are to determine if each ordered pair is a solution to the given system of equations

The given system of equations is

-9x + 2y = 6

5x - 3y = 8

  • For (7, 9)

That is,

x = 7, y = 9

Putting the values into the first equation

Is -9(7) + 2(9) = 6

-63 + 18 = 6

-45 ≠ 6

Thus, (7,9) is not a solution

  • For (0, 3)

That is,

x = 0, y = 3

Putting the values into the first equation

Is -9(0) + 2(3) = 6

0 + 6 = 6

6 = 6

The ordered pair satisfies the first equation

Testing for the second equation

Is 5(0) - 3(3) = 8

0 - 9 = 8

-9 ≠ 8

Thus, (0, 3) is not a solution

  • For (5, -4)

That is,

x = 5, y = -4

Putting the values into the first equation

Is -9(5) + 2(-4) = 6

-45 - 8 = 6

-53 ≠ 6

Thus, (-5,4) is not a solution

  • For  (-2, -6)

That is,

x = -2, y = -6

Putting the values into the first equation

Is -9(-2) + 2(-6) = 6

18 - 12 = 6

6 = 6

The ordered pair satisfies the first equation

Testing for the second equation

Is 5(-2) -3(-6) = 8

-10 + 18 = 8

8 = 8

The ordered pair satisfies the second equation

∴ The ordered pair that is a solution to the system of equations is (-2, -6)

Hence, the only ordered pair that is a solution to the given system of equations is (-2, -6)

Given = 1/(−3), what is ((+ℎ)−())/ℎ ?
exis [7]

Answer:

-(1/(x+h-3)(x-3))

Step-by-step explanation:

y=1/(x-3)

(f(x+h)-f(x))/h=(1/(x+h-3)-1/(x-3))/h=-(1/(x+h-3)(x-3))

1. a type of bamboo holds a Guinness world record for the fastest growing plant.is can grow 91cm a day. how fast in inches per h
nikdorinn [45]

1-

Given length is 91 cm

1 cm = 0.3937 inch

so, 91 cm = 91* 0.3937 = 35.826 inches

1 day = 24 hours

In 24 hours the bamboo grows = 35.826 inches

In one hour it will grow = \frac{35.826}{24}

= 1.492 inches per hour. Hence the bamboo grows 1.492 inches per hour.


2-

We have to convert hours and seconds in minutes.

1 hour = 60 minutes

so 10 hours = 60 * 10 = 600 minutes.

60 seconds = 1 minute

so 24 seconds = \frac{24}{60} = 0.4 minutes.

Now we have been given the total time as 10 hours, 39 minutes and 24 seconds

So adding all values in minutes, we get

600 + 39 + 0.4 = 639.4 minutes

So Saturn takes 639.4 minutes to complete one rotation

Given equation is 0.4(30h)+30h

0.4(30h) represents the amount of tax Kimberly has to pay.
