Give work for equations following:<br><br> -x+2y<-4<br> 2x+3y>6<br><br> thanks sooooo much!!!!

Schach [20]

Answer: See below

Step-by-step explanation:

A) $-x+2y < -4$

$-x+2y-2y < -4-2y$

$-x < -4-2y$

Multiply both sides by -1 and reverse the inequality:

$\left(-x\right)\left(-1\right) > -4\left(-1\right)-2y\left(-1\right)$

$x > 4+2y$

B) $2x+3y > 6$

$2x+3y-3y > 6-3y$

$2x > 6-3y$

$\frac{2x}{2} > \frac{6}{2}-\frac{3y}{2}$

$x > \frac{6-3y}{2}\\x > 3-\frac{3y}{2}$

I’m trying to understand what it’s asking not sure if this is correct or not

Artemon [7]

Answer:

Step-by-step explanation:

First of all, the term multiple needs to be defined.

When a number is multiplied by another number other then zero, we get the multiple as result.

i.e. Multiples of 2 are: 2, 4, 6, 8, 10

To find the Least Common Multiple of numbers, we list the multiples of those numbers and then the samllest factor that is common in both lists is chosen as least common multiple.

1. 10, 20

Multiples of 10: 10, 20, 30, 40, 50, 60, 70, 80

Multiples of 20: 20, 40, 60, 80, 100

Least Common Multiple: 20

2. 3, 9

Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27

Multiples of 9: 9, 18, 27, 36, 45

Least Common Multiple: 9

3. 12, 24

Multiples of 12: 12, 24, 36, 48, 60, 72

Multiples of 24: 24, 48, 72, 96

Least Common Multiple: 24

4. 25, 45

Multiples of 25: 25, 50, 75, 100, 125, 150, 175, 200, 225, 250

Multiples of 45: 45, 90, 135, 180, 225, 270, 315

Least Common Multiple: 225

5. 5, 10

Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40

Multiples of 10: 10, 20, 30, 40, 50, 60

Least Common Multiple: 10

6. 49, 56

Multiples of 49: 49, 98,147, 196, 245, 294, 343, 392, 441

Multiples of 56: 56, 112, 168, 224, 280, 336, 392, 448

Least Common Multiple: 392

This method of finding LCM is brute force and requires more time.

Another method is by using GCD(Greatest Common Divisor). It is the greatest positive integer number which completely divides all the numbers in consideration.

The product of the numbers is divided by their GCD to find the LCM.

i.e. for Q6

GCF(49, 56) = 7

LCM(49,56)= (49*56)/7

=2744/7=392

On Naomi's cell phone plan, the amount she pays each month for international text messages is proportional to the number of inte

Margaret [11]

A) The constant of proportionality in this proportional relationship is $k = \frac{y}{x}$

B) The equation to represent this proportional relationship is y = 0.2x

<em><u>Solution:</u></em>

Given that,

The amount Naomi pays each month for international text messages is proportional to the number of international texts she sends that month

Therefore,

This is a direct variation proportion

$\text{ amount paid each month } \propto \text{ number of international texts sent that month}$

Let "y" be the amount that Naomi pays each month

Let "x" be the number of international texts she sends that month

Therefore,

$y \propto x$

y = kx -------- eqn 1

Where, "k" is the constant of proportionality

Thus the constant of proportionality in this proportional relationship is:

$k = \frac{y}{x}$

Last month, she paid $3.20 for 16 international texts

Therefore,

y = 3.20

x = 16

Thus from eqn 1,

$3.20 = k \times 16\\\\k = \frac{3.20}{16}\\\\k = 0.2$

Substitute k = 0.2 in eqn 1

y = 0.2x

The equation would then be y = 0.2x

A farmer plants 987 apple trees in 9 rows. Can each row have the same number of trees? How do you know?

alexira [117]

Answer:

No,

Step-by-step explanation:

each row can not have the same number of trees as the number 987 can not be evenly divided into 9 rows.
