6 0

Step-by-step explanation:

(1) x+10y=20, x=20,y=2

(2) 6x+y=-18, x=-3,y=-18

(3) 2x-9y=-36, x=-18,y=4

(4) x=-6,y=-15

(5) x=9,y=12

(6) x=-18,y=-3

(7) x=16,y=-6

(8) x=14,y=8

(9) x=-12,y=9

(10) x=-15,y=-6

(11) x=12,y=10

If $60 is the original price and $9 is the amount discount what is 15% of the original price
pantera1 [17]

I'm kinda confused by this question, but, If $60 is the original price, and you want to know what 15% of the original price ($60) is.. It would be $9, the "amount discount".

If this isn't the answer you wanted please tell me and explain the question a bit more to me if you can and I will try my best to help.

Thank you.

Given that y is inversely as x+3 and that y=4 when x =2 (a)express y in terms of x (b)find the value of y when x =5 .
myrzilka [38]

a. Expressing y in terms of x, y = 20/(x + 3)

b. When x = 5, the value of y is 2.5

The question has to do with inverse variation.

<h3>What is inverse variation?</h3>

Inverse variation is variation in which one quantity varies inversely as the other.

<h3>a. How to express y in terms of x?</h3>

Given that y is inversely as x + 3 and that y = 4 when x = 2.

Since y varies inversely as x + 3, we have

y ∝ 1/(x + 3)

y = k/(x + 3)

When y = 4, x = 3. So

y = k/(x + 3)

4 = k/(2 + 3)

4 = k/5

k = 4 × 5

k = 20

So, y = k/(x + 3)

y = 20/(x + 3)

So, expressing y in terms of x, y = 20/(x + 3)

<h3>b. Find the value of y when x = 5.</h3>

Since  y = 20/(x + 3)

Substituting x = 5 into the equation, we have

y = 20/(x + 3)

y = 20/(5 + 3)

y = 20/8

y = 5/2

y = 2.5

So, when x = 5, the value of y is 2.5
