Answer:

4x-2y=0

Step-by-step explanation:

Ok

so you need to subtract

(3x+2y=22)-(-x+4y=22)

Use distributive property and take away parenthesis

3x+2y=22+x-4y=-22

----------------------------

3x+2y=22

x-4y=-22

------------------------------

4x-2y=0

Answer:

<em>( </em>\frac{22}{7}<em> , </em>\frac{44}{7}<em> ) </em>

Step-by-step explanation:

3x + 2y = 22 ....... <em>(1)</em>

- x+ 4y = 22 ........ <em>(2)</em>

3 × <em>(2)</em> + <em>(1)</em>

<u><em>(3x - 3x)</em></u> + (2y + 12y) = 22 + 66 ( variable "x" is eliminated )

14y = 88

y = \frac{44}{7}

- x + 4( \frac{44}{7} ) = 22

x = \frac{176}{7} - \frac{154}{7} = \frac{22}{7}

<em>( </em>\frac{22}{7}<em> , </em>\frac{44}{7}<em> )</em>

Can anybody tell me the answers to number 1, 2 &amp; 3 ???!!!!
Novay_Z [31]

Problem 1

Domain = {-1, -3, 2, 1}

Range = {5, 0, 2}

The domain is the set of possible inputs and the range is the set of possible outputs. This is a function because each input goes to exactly one output.

========================================

Problem 2

This is a function as well. We do not have any input going to multiple outputs.

Domain = {-2, -3, 5}

Range = {6, 7, 8}

========================================

Problem 3

This is not a function. The input -4 goes to more than one output (outputs 3 and -1 at the same time)

Domain = {-4, -2, 0}

Range = {3, -1, -2, 4}

Which expression is equivalent to one over 3p + 15?
Doss [256]

we know that

the expression " one over (3p+15)"  is equivalent to

\frac{1}{(3p+15)} --------> expression A

and

 3p+15=3(p+5) --------> expression B

substitute the expression B in the expression A

\frac{1}{(3p+15)}=\frac{1}{3(p+5)} -----> one over three(p + 5)

therefore

<u>the answer is the option </u>

one over three(p + 5)

HELP ME OUT ASAP PLS 20POINTS IF U DO! On Friday, a bowling alley made $842.72 from lane rentals and $412.38 from the concession
ElenaW [278]

Answer:

  $2611.05

Step-by-step explanation:

  earnings = lane rentals + concessions

<u>Friday</u>:

  earnings = $842.72 +412.38 = $1255.10

<u>Saturday</u>:

We assume "down by 1/8" means the value was 1 -1/8 = 7/8 that of the previous day. Likewise, "increased by 1/2" is assumed to mean the value was 1 + 1/2 = 3/2 that of the previous day.

  earnings = 7/8×$842.72 + 3/2×412.38 = $1355.95

__

Then the total earnings for both days were ...

  $1255.10 +$1355.95 = $2611.05
