Which of the following is a characteristic of the fungus kingdom? All are single-celled Make their own food Cell nucleus is abse

Anastasy [175]

The characteristic of the fungus kingdom is that they have eukaryotic cells. Organisms in the fungus kingdom are all multi-cellular. Because of their lack of chloroplast they are not able to make their own food like plants. Multi-celled organisms have cell nucleus unlike single celled. The fungus also contains a cell wall.

<h2>Writing an Equation of a Line in Slope-Intercept Form</h2><h3>Answer:</h3>

$y = [ -2 ] x + [ 1 ]\\$

<h3>Step-by-step explanation:</h3>

<em>Please refer to my answer from this Question to know more about Slope-Intercept Form: <u>brainly.com/question/24599351</u></em>

We must first find the slope.

<em>Please refer to my Answer from this Questions to know more about Slopes of a Line:</em>

<em><u>brainly.com/question/24640665</u></em>
<em><u>brainly.com/question/24638053</u></em>

We can see the marked points, $(0,1)$ and $(4, -7)$ , are on the line.

Solving for the slope:

$m = \frac{y_2 -y_1}{x_2 -x_1} \\ m = \frac{-7 -1}{4 -0} \\ m = \frac{-8}{4} \\ m = -2$

Now we can now solve for the $y$ -intercept.

<em>Please refer to the second paragraph of my Answer from this Question to know more about y-intercepts: <u>brainly.com/question/24606058</u></em>

We can see that the line intersected the $y$ -axis at $(0,1)$ so $b = 1$ .

Irina,Teodor și Andrei au participat la un concurs.Irina și Teodor au obținut împreună 559 de puncte,Teodor și Andrei au împreun

andreev551 [17]

Answer:

Numărul de puncte:

Irina a obținut = x = 245 puncte

Teodor a obținut = y = 314 puncte

Andrei a obținut = z = 286 puncte

Step-by-step explanation:

Să ne reprezentăm

Numărul de puncte:

Irina a primit = x

Teodor got = y

Andrei got = Z

Irina, Teodor și Andrei au participat la un concurs.

Irina și Teodor au obținut 559 de puncte împreună

x + y = 559 ....... Ecuația 1

Teodor și Andrei au obținut 600 de puncte împreună

y + z = 600 ...... Ecuația 2

y = 600 - z

Irina și Andrei 531 puncte.

x + z = 531 ....... Ecuația 3

Substitui

600- z pentru y în ecuația 1

x + 600 - z = 559

Colectează ca termeni

x - z = 559 - 600

x - z = -41 ..... Ecuația 4

Combinând ecuația 3 și 4 împreună

x + z = 531 ....... Ecuația 3

x - z = -41 ..... Ecuația 4

Am face și ecuația 3 și 4 împreună pentru a elimina z

2x = 490

x = 490/2

x = 245 puncte

Rezolvarea pentru z folosind ecuația 4

x - z = -41 ..... Ecuația 4

245 - z = -41

Colectează ca termeni

z = 245 + 41

z = 286 puncte

Rezolvarea pentru y

y = 600 - z

y = 600 - 286

y = 314 puncte

Prin urmare,

Numărul de puncte:

Irina a obținut = x = 245 puncte

Teodor a obținut = y = 314 puncte

Andrei a obținut = z = 286 puncte
