18x + 3y = -21 !!!!!!!!!!
alekssr [168]

18x+3y=-21

slope -intercept form: y=mx+b

move 18x to the other side

sign changes from +18x to -18x

18x-18x+3y=-18x-21

3y=-18x-21

divide both sides by 3 to find slope-intercept form

3y/3=-18x/3-21/3

y=-6x-7

answer: y=-6x-7

How to solve pythagorean theorem i need an assay someone help
Veronika [31]

Answer:

first write the formula

Step-by-step explanation:

Hypotenuse^2 = Perpendicular ^2 + Base^2

only applicable for a right triangle (one of the sides is of measure 90 degree

Give an example

let is assume in Triangle ABC, angle B = 90 degrees

AB = 3cm

BC = 4 cm

to find AC or hypotenuse

Solution

by using pythagoras formula we get

(AB)^2 + (BC)^2 = (AC)^2

(3)^2 + (4)^2 = (AC) ^2

9 + 16 = (AC)^2

25 = (AC)^2

Root of 25 = AC

5cm =AC

Write about how pythagoras theorem was formed

mathematician who derived it

in which year

Application of Pythagorean theorem

Pythagorean Triplets etc.

I think this willbe enough for an essay

GOOD LUCK FOR THE FUTURE! :)
