-2x + y = 0<br> x - y = -3
miv72 [106K]

Answer:

The value of x is 3 and y is 6.

Step-by-step explanation:

You can solve this simultaneous equation by elimination method :

- 2x + y = 0 -  -  - (1)

x - y =  - 3 -  -  - (2)

(1) + (2)

- 2x + y + x  + (- y) = 0 + ( - 3)

- x =  - 3

x = 3

substitute \: x = 3 \: into \: (2)

(2)⇒

3 - y =  - 3

- y =  - 6

y = 6

Use the given functions to find f (g(x)), and give the restrictions on x.
torisob [31]

Answer:

f(g(x)) = \frac{10x-9}{3 + 3x}

Step-by-step explanation:

Given

f(x) = \frac{1}{x} - 3

g(x) = \frac{3}{x} + 3

Required

Find f(g(x))

If: f(x) = \frac{1}{x} - 3

Then:

f(g(x)) = \frac{1}{3/x + 3} -3

Solve the denominator (take LCM)

f(g(x)) = \frac{1}{\frac{3+3x}{x}} -3

f(g(x)) = \frac{x}{3 + 3x} - 3

It can be solved further as:

f(g(x)) = \frac{x-3(3 + 3x)}{3 + 3x}

f(g(x)) = \frac{x-9 + 9x}{3 + 3x}

f(g(x)) = \frac{10x-9}{3 + 3x}

A candy company puts 7 gumdrops in each bag. How many gumdrops will the company need to fill 9 bags?​
stiv31 [10]

Answer:

63

Step-by-step explanation:

In these 9 bags, each must have 7 gumdrops. So, we can add 7 nine times to itself. 7 + 7 + 7 + 7 + ... = 63

OR HERE'S A FASTER WAY *WINK WINK*

Instead of doing repeated addition, we can <u>multiply</u> 7 and 9 together.

<u>Why multiply?</u>

We're going to multiply 7 x 9 so that it means seven gumdrops for <em>each</em> of nine bags.

7 x 9 = 63.
