Answer:

x=3; y=3

Step-by-step explanation:

y = -1/2 x + 9/2

so if we multiply by 2 on both sides

2y = -x + 9

and we know that y = 3x-6

so we get

2(3x-6)=-x+9

6x-12 = - x + 9

7x = 21

x = 3

y = 3 * 3 - 6

y=3

---

x=3, y=3

You put them in the equation and they should work.

(This question is related to the picture question)
UNO [17]

Answer:

5. f(x) = 10,000 (1.5)^x

Step-by-step explanation:

==>>We would have to multiply the original amount by 1.50^x because the initial amount would be 1, and 50% increase would be .5 so 1.5 and you raise it to the number of years to show the total increase.

  • Let's test it

Initial: 10,000

After 1 year

10,000 + (.5*10000)

10,000 + 5000 = 15,000

--

After 2 years

15,000 + (.5*15000)

15,000 + 7500 = 22,500

--

Let's try our equation.

f(x) = 10,000 (1.5)^x

x=2

10,000(1.5)^2

10,000(2.25) = 22,500

*Edit: I just seen that the question is related to the picture question

Quadrilateral GHIJ is similar to quadrilateral KLMN. Find the measure of side NK.
Leokris [45]

Answer:
NK = 14.4

Step-by-step explanation:

Given the following question:

We know that the two sides are similar
JI = 3, NM = 7.2

<u>The scale factor is 2.4 since....</u>

3\times2.4=7.2


Knowing the two sides are similar and if we multiply JI by 2.4, we get NM we can easily do the same for JG and NK.

JG = 6
6\times2.4=14.4
=14.4

NK = 14.4

Hope this helps.
