Answer:

  2x -3y = 12

Step-by-step explanation:

The parallel line will have the same variable coefficients, but a different constant appropriate to the given point. Using that point, we find the constant to be ...

  -2x +3y = constant

  -2(3) +3(-2) = -6 -6 = -12

The equation can be written ...

  -2x +3y = -12

We prefer the "standard form", which has a positive leading coefficient. To get that, we can multiply the equation by -1.

  2x -3y = 12

For part A, there are 4 equal lengths put together and the sum of them is 36. So dividing 36/4 gives us 9.

So the length of each edge is <u>9 cm</u>!

For part B, finding surface area means the total area of the cube on its six faces.

So for one face of the cube, the area is

9 × 9 = 81 cm^2

There are 6 faces so we multiply 81 by 6 and get 486 cm^2.

Hope this helps!

In which of the following functions would it be appropiate to use only positve integers for the domain?Select all that apply.
gayaneshka [121]

Complete Question:

<em>As you may have unintentionally forgotten to add the answer choices in your question, but I was able to find the complete the question and answering your question based on this as it may surely clear your concepts. Here is the complete question. </em>

In which of the following functions would it be appropriate to use only positive integers for the domain? Select all that apply.

The function c(p) represents The cost for P people to attend the movies. The function m(t) represents the miles driven over T hours. The function t(m) represents the average high temperature for a given number of months. The function p(w) represents the prophet of a farmer who sells whole watermelons. The function h(n) represents the number of person-hours it takes to assemble n engines in a factory.

Answer Explanation:

Domain is termed as all the input values on a certain interval that define the function.

Here are the appropriate function scenarios where it is appropriate to use only positive integers.

<em />

<em>The function c(p) represents The cost for P people to attend the movies. </em>

As the function c(p) contains people. And People are not counted as negative, although they can be zero. So, only positive integers should be appropriate to use in this scenario.

<em>The function m(t) represents the miles driven over T hours</em>

As the function m(t) contains miles. And miles are not counted as negative. They normally initiate with 1. So, only positive integers should be appropriate to use in this scenario.

<em>The function t(m) represents the average high temperature for a given number of months.</em>

As the function t(m) contains months. And months are not counted as negative. They normally initiate with 1. So, only positive integers should be appropriate to use in this scenario.

<em>The function p(w) represents the prophet of a farmer who sells whole watermelons. </em>

As the function p(w) contains the number of watermelons. And watermelons are not counted as negative. They normally initiate with 1. So, only positive integers should be appropriate to use in this scenario.

<em>The function h(n) represents the number of person-hours it takes to assemble n engines in a factory.</em>

As the function h(n) contains the number of engines. And engines are not counted as negative. They normally initiate with 1. So, only positive integers should be appropriate to use in this scenario.

Can someone help please I don’t need the full explanation just some help

<h3>Answer:  13/15</h3>

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

Explanation:

20 people play cricket, 8 of them play both, so 20-8 = 12 people play cricket only.

14 play football, 8 play both, so 14-8 = 6 play football only

We have,

  • 12 people play cricket only
  • 6 people play football only
  • 8 people play both cricket and football

So far, this tallies to A = 12+6+8 = 26 people who play one sport only, or both sports mentioned. Now add in the four people who play neither sport and we get to B = 26+4 = 30 students overall.

The probability of selecting someone who plays at least one of the two sports mentioned is A/B = 26/30 = (13*2)/(15*2) = 13/15

This is effectively saying: if we had 15 students, then 13 of them play at least one of the two sports mentioned.
