Answer:

$\displaystyle [3, 5]$

Step-by-step explanation:

{8x + 8y = 64

{y = x + 2

8x + 8[x + 2] = 64

8x + 8x + 16 = 64

16x + 16 = 64

- 16 - 16

__________

$\displaystyle \frac{16x}{16} = \frac{48}{16}$

$\displaystyle x = 3$ [Plug this back into both equations above to get the y-coordinate of 5]; $\displaystyle 5 = y$

* This is using the Substitution Method.

Solve |2x - 1| + 3 = 6.

umka21 [38]

Answer:

x =2 x = -1

Step-by-step explanation:

|2x - 1| + 3 = 6.

Subtract 3 from each side

|2x - 1| + 3-3 = 6-3

|2x - 1|= 3

An absolute value has two solutions, one positive and one negative

2x-1 =3 2x -1 = -3

Add 1 to all sides

2x-1+1 =3+1 2x-1+1 = -3+1

2x = 4 2x =-2

Divide by 2

2x/2 = 4/2 2x/2 = -2/2

x =2 x = -1

If `f(x)=x^2-81` and `g(x)=(x-9)^(-1)(x+9)`, find `g(x)xxf(x)`.

marshall27 [118]

Answer:

$g ( x ) * f ( x ) = ( x + 9 ) ^ 2$

Step-by-step explanation:

We are given the following two functions and we are to find $g(x) * f(x)$ :

$f(x)=x2-81$

$g(x)=(x - 9)^{-1} ( x + 9)$

$g(x)*f(x)=x^{-81} * \frac{x+9}{x-9}$

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

$g ( x ) * f ( x ) = ( x + 9 ) ( x + 9 )$

$g ( x ) * f ( x ) =( x + 9 ) ^ 2$

HELP ME HELP ME I GIVE BRAINEST!

Julli [10]

Answer:

3 batches

Step-by-step explanation:

We have been given that a sports drink recipe calls for 5/3 tablespoons of powered drink mix for every 12 ounces of water.

We need to find out how many batches can be made with 5 tablespoons of drink mix and 36 ounces of water.

So, from the given information we see that to make 1 batch of sports drink we need 5/3 tablespoons of powdered drink mix for every 12 ounces of water.

So, we have 36 ounces of water. But we know that for 1 batch of sports drink we need to 12 ounces. So with 36 ounces of water we can make

= 3 batches

Therefore, we can make 3 batches of sports drink from 5 tablespoons of powdered drink mix and 36 ounces of water.
