Answer:

Step-by-step explanation:

(4x-5) - (3x-10) = ?

(4x-5) - 1 (3x-10) = ? DISTRIBUTE THE INVISIBLE -1 to (3x-10)

Turns into: 4x - 5 - 3x + 10

Which equals: x + 5

A group of 4 people went to a movie. Each person bought a large drink and a small box of popcorn. They paid a total of $33.00 fo

MariettaO [177]

I'm pretty sure your answer should be $4.50 for each drink. I multiplied the price of the popcorn (3.75 including the tax) by 4, since there are 4 people, which gave me 15. Then take 15 out of 33.00 which gave me 18. Divide 18 by 4 (number of people) and get 4.5 or 4 1/2 which equals out to $4.50 for each drink.

3.75 · 4= 15

33.00 - 15= 18

18 ÷ 4= 4.5 or 4 1/2

Hope this helps! =^-^=

Add the equations. What value belongs in the green box? 3x + 2y = 9 -x - 2y = 4 [?] + [?] = [?] A. 4x B. 2x C. -3x D. -2x

Naddika [18.5K]

Consider the first blank is the green box.

Given:

The equations are

$3x+2y=9$

$-x-2y=4$

To find:

The value belongs in the green box

Solution:

We have,

$3x+2y=9$ ...(i)

$-x-2y=4$ ...(ii)

Adding (i) and (ii), we get

$3x+2y-x-2y=9+4$

$(3x-x)+(2y-2y)=13$

$2x+0=13$

So, the value for the first black is 2x. It means the value belongs in the green box is 2x.

The values of three blanks are 2x, 0 and 13 respectively.

Therefore, the correct option is B.

Help!!!!!!!!!!!!!!!!!!!!!!!

Nataly [62]

Hello.

Firstly, let's isolate x on the equation:

$\mathsf{f(x) = 3x + 3} \\ \\ \mathsf{y = 3x + 3} \\ \\ \mathsf{-3x = -y + 3} \\ \\ \mathsf{x = \dfrac{-y + 3}{3}}$

Now, we can replace 'x' for 'y' and vice-versa:

$\mathsf{f^{-1}(x) = \frac{-x + 3}{3}`}$

Hope I helped.
