Answer:

equation in standard form is -3x + 5y = -26

Step-by-step explanation:

standard form of equation of line is

Ax + By = C

where A,B and C are integers.

such line has slope -A/B

Another form of line equation is slope intercept form, which can be written as

y = mx+ c

since in problem m = 3/5

thus, equation is

y = 3/5 x + c

Given that (2,-4) passes through this line, this point will satisfy the above equation

-4 = 3/5 *2 + c

=> - 4 = 6/5 + c

=> c = -4 -6/5 = (-4*5 - 6)/5

=> c = (-20 - 6)/5 = -26/5

Thus, equation in slope intercept form is

y = 3/5 x -26/5

lets rewrite this equation in Ax + By = C

Multiplying LHS and RHS by 5 we have

5y =( 3/5 x)* 5 - (26/5 * 5)

=> 5y = 3x - 26

we have to bring 3x on LHS for that

we subtract 3x from both side

5y -3x = 3x - 26 -3x

=> 5y -3x = - 26

rearranging the equation

-3x + 5y = -26

Thus, equation in standard form is -3x + 5y = -26

Based on the excerpt, which statement best describes

Kobotan [32]

The statement that best describes the Humbaba's effect on the epic's plot is (d) Humbaba creates tension and suspense in the story.

Step-by-step explanation:

<u>Humbaba creates tension and suspense in the story.</u>

In this story the main character Gilgamesh has a dream and he discusses his dream with Enkidu who says that the dream he had was actually a message from the Lord Shamash that he is protecting him and he should not loose his courage against a war with Humbaba. In this story Humbabab is described as a evil monster which has a body of a eagle and the head of a lion and who produces fire flames from his mouth

So we can say that the , Gilgamesh’s dream was a divine intervention to communicate the message that he has the power to defeat Humbaba.

Thus we can say that he Humbaba's effect on the epic's plot is (d) Humbaba creates tension and suspense in the story.

Answer:

m<4 = 117 degrees

Step-by-step explanation:

Knowing that angle 1 is 63 degrees, we can look at the other angle on the same side of the line, angle 4.

Angles on one side of a line add to 180 degrees.

180 - 63 = 117

If using the method of completing the square to solve the quadratic equation

lubasha [3.4K]

Answer:

31.25

Step-by-step explanation:

The general form of a complete square would be (x + a)^2 + b

Given an equation of X^2 + 15X + 25 = 0,

the idea is to reduce it into the form if (X + C)^2

which can be expanded into X^2 + 2XC + C^2

In this case 15 will be our 2C So our c will be 7.5.

Substituting in these numbers,

We have X^2 + 15X + (7.5)^2 = 0

However our original equation has 25 for its C^2, thus

we need to add 31.25 in order to get (7.5)^2

The final completed form will be (X + 7.5)^2 - 31.25
