How do I solve this?

Answer:

See below.

Step-by-step explanation:

Use the converse of the Triangle Proportionality Theorem.

If a segment divides two sides of a triangle into proportional lengths, then the segment is parallel to the third side of the triangle.

Here we have triangle CED.

Segment AB divides sides EC and ED.

Side EC is divided into segments EA and AC.

Side ED is divided into segments EB and BD.

Now we check the ratios of the lengths of the segments.

Is EA/AC = EB/BD?

EA/AC = 3.75/5 = 0.75

EB/BD = 4.5/6 = 0.75

Since the ratios are equal, the segment, AB, is parallel to the third side of the triangle, CD.

AB and CD are parallel because when 2 lines in a plane are parallel it means they do not intersect

Since you can see that the triangle is isosceles triangle the length of the 2 side will be same

2n+9=7n-18
9+18=7n-2n
27=5n

2. Each of the following lines has a slope that can be determined by examining the graph. Use another point
Natali [406]

The slope, y-intercept and the equation of the following graph are as follows:

1(a)

slope : 1

y-intercept: 2

Equation: y = x + 2

(b)

slope : -  1 / 3

y-intercept: - 1

Equation: y = - 1 / 3x - 1

2.

(a)

slope : 3 / 4

y-intercept: 5 / 4

Equation: y = 3 / 4 x + 5 / 4

(b)

slope : - 3 / 2

y-intercept: 1 / 2

Equation: y = - 3 / 2 x + 1 / 2  

<h3 />

<h3>Slope intercept equation</h3>
  • y = mx + b

where

m = slope

b = y-intercept

Therefore lets find the slope, y-intercept and equation of the following graph.

1.

(a)

(0, 2)(1, 3)

m = 3 - 2 / 1 - 0 = 1

b = 2

y = x + 2

(b)

(0, -1)(-3, 0)

m = 0 + 1 / -3 - 0 = - 1 / 3

b = -1

y = - 1 / 3x - 1

2.

(a)

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

m = -1 - 2 / -3 - 1 = 3 / 4

2 = 3 / 4 (1) + b

b = 2 - 3 / 4  = 5 / 4

y = 3 / 4 x + 5 / 4

3.

(b)

(-3, 5)(1, -1)

m = - 1 - 5 / 1 + 3 = - 6 / 4 = - 3 / 2

-1 = - 3 /2 (1) + b

b = -1 + 3 / 2 = 1 /2

y = - 3 / 2 x + 1 / 2

How can you find the rate of the variablws being graphed?
Anni [7]
You first see where it starts on the y axis. whether it be 1 or 2 or 3 or even 3. Than you look at the slope by counting from that point from the y axis going up and over until you reach a point. not a line a point. and if it's 3 up and one over than it's 3x. But it's for example it's 3 up and 2 over than it's 3/2x. Than you set up the equation as y= mx + b. m being the slope that you found. x just remains the same. and b is where the point started on the y axis
