3× + y = 8, 4× - 3y=2​

Mathematics

Dimas [21]2 years ago

Answer:

x=2

y=2

Step-by-step explanation:

You can use the process of elimination

<em>x </em>can't be 3 because than the first question would be 9+<em>y</em>=8 which is even bigger than the answer.

So now, we try 2. <em>x=2</em>

<u><em>6+y=8</em></u> which =

<u><em>6+2=8</em></u>

So<em> y</em> must be two

Then we try it on the

Second one.

<u><em>8-6=2</em></u> which makes sense.

Hope it helps

Answer:

x = 2

y = 2

Step-by-step explanation:

3x + y = 8..…...(1)× -3

4x - 3y = 2......(2)× 1

-9x - 3y = -24.......(3)

4x - 3y = 2..…..........(4)

Cancel -3y - 3y

-9x - 4x = -24 - 2

-13x = -26

Divide both sides by -13

x = 2

Substitute for the value of y

3x + y = 8

3(2) + y = 8

6 + y = 8

y = 8 - 6

y = 2

guapka [62]

Answer:

The Probability that the spinner landed on the colors blue and green in any order = 2/9

Step-by-step explanation:

Given - Azul spun a tri-color spinner twice.

To find - What is the probability that the spinner landed on the colors blue and green in any order?

Solution -

Given that,

A tri-color spinner spun twice

So,

The Sample Space, S = {BB, BG, BY, GB, GG, GY, YB, YG, YY}

⇒n(S) = 9

Now,

Let A be an event that the spinner landed on the colors blue and green

So,

A = {BG, GB}

⇒n(A) = 2

Now,

Probability that the spinner landed on the colors blue and green in any order = n(A) ÷ n(S)

         = 2 ÷ 9

∴ we get

The Probability that the spinner landed on the colors blue and green in any order = 2/9

. Write the exponential function modeling an initial population of 67,000 and a relative growth rate of 1.7% per year. What popu
Vlada [557]

Answer:

In 37 years the population will be 125,012

Step-by-step explanation:

Giving the following information:

Initial population (PV)= 67,000

Growth rate (g)= 1.7%= 0.017

Number of years (n)= 37

<u>First, we will establish the future value (FV) formula:</u>

FV= PV*(1+i)^n

FV= 67,000*(1.017^n)

<u>Now, for 37 years:</u>

FV= 67,000*(1.017^37)

FV= 125,012

In 37 years the population will be 125,012
