Learning Task 2. Find the equation of the line . Write in slope intercept form

Biology
1 answer:
Damm [24]3 years ago
6 0

Answer:  

(1)  m = -5, b= 1

    \frac{x}{a} + \frac{y}{b} = 1  

put b=1 (given)

\frac{x}{a} + \frac{y}{1}  = 1 => y = -x/a + 1

-1/a is representing slope here which is given as -5

-1/a = -5 => a = 1/5

slope intercept form

y = mx +b

y = -5x + 1

standard form

5x +y = 1

(2). (1, -2), (3, 3)

m = 5/2

slope intercept form

y - 3 = 5/2*( x -3)

y = 5x/2  -9/2

standard form

5x -2y = 9

(3). (-2, 0) and (0,5)

  m = 5/2

slope intercept form

y - 0 = 5/2 ( x+2)

y = 5x/2 + 5

standard form

5x -2y = -10

(4). a = 2, b = -7

   \frac{x}{2} + \frac{y}{-7}  =1

slope intercept form  

y = 7x/2 -7

standard form

7x -2y =14

(5). m=2,(3,-1​)

  slope intercept form  

y +1 = 2(x -3)

y = 2x -7

standard form

2x -y = 7

During meiosis, errors occur during chromosome replication. Which term describes the rearranging of genetic material between non
7nadin3 [17]

Answer:

The correct answer is: translocation.

Explanation:

Translocations are <u>chromosomal abnormalities</u> that are caused by an error that can occur during meiosis <u>when a piece of a chromosome breaks off and it is attached to another chromosome that is not its homologous pair. </u>

There are two types of translocations when taking into account if there were a loss or gain of genetic material, or if it weren't. The type of translocation where there's no loss or gain of genetic material is called balanced, since the information is still there but in a different location.

- Saliva mixes with food and changes starches into sugars.

- The stomach kills some bacteria and breaks food down into chyme.

- Nutrients from dissolved food are absorbed from the small intestine into the bloodstream.

- Water and nutrients are absorbed by the large intestine. Chyme becomes waste matter.
