How do you rewrite this problem in slope-intercept form
Sergio039 [100]

Solution

-6x - 3y = 9              Add 6x to both sides

-6x + 6x - 3y = 9 + 6x

-3y = 9 + 6x             Or more conventionally

-3y = 6x + 9             Divide by - 3

y = 6x/-3 + 9/-3

y = - 2x - 3

Triangle A B C has centroid G. Lines are drawn from each point through the centroid to the midpoint of the opposite side to form
d1i1m1o1n [39]

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The length of GF is 254 units.

<h3>What is a triangle?</h3>

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°.

Since a centroid of a triangle divides the median into a ratio of 2:1. Therefore, the ratio of AG: DG is,

AG / DG = 2/1

(19x+14)/(9x+20) = 2/1

19x + 14 = 18x + 40

19x - 18x = 40 - 14

x = 26

Assuming the triangle is an equilateral triangle, therefore, the length of GF will be,

GF = DG = 9x+20

GF = DG = 9(26) + 20

GF = 254 units

Hence, the length of GF is 254 units.

What number is 45% of 60, as well as 8 is 0.5% of what number?
JulsSmile [24]
Hi!

We can set up proportions to solve these.

1. \frac{x}{60}  \frac{45}{100}

2. \frac{8}{x}  \frac{0.5}{100}

Cross multiply to solve for x

1. 60 x 45 = 2700
2700/100 = 27

2. 8 x 100 = 800
800/0.5 = 1600
(Tip: dividing by 0.5 is the same as multiplying by 2)

The answers are
1. 27
And
2. 1600

Hope this helps! :)
