Suppose given △ABD and △CBD.
patriot [66]

Answer:

The required result is proved with the help of angle bisector theorem.

Step-by-step explanation:

Given △ABD and △CBD, AE and CE are the angle bisectors. we have to prove that \frac{AD}{AB}=\frac{DC}{CB}

Angle bisector theorem states that an angle bisector of an angle of a Δ divides the opposite side in two segments that are proportional to the other two sides of triangle.

In ΔADB, AE is the angle bisector

∴ the ratio of the length of side DE to length BE is equal to the ratio of the line segment AD to the line segment AB.

\frac{DE}{EB}=\frac{AD}{AB}   →  (1)

In ΔDCB, CE is the angle bisector

∴ the ratio of the length of side DE to length BE is equal to the ratio of the line segment CD to the line segment CB.

\frac{DE}{EB}=\frac{CD}{CB}    →  (2)

From equation (1) and (2), we get

\frac{AD}{AB}=\frac{CD}{CB}

Hence Proved.

Easy algebra! Please help! Will mark brainiliest!
Inessa [10]

Answer:

y = 97749e^{x}

Step-by-step explanation:

a) Let Area be the independent variable and Price of the homes sold be dependent on the area.

Let x represents the area and y represents the price.

We will plot the data in excel using trend line function.

The model so obtained is:

y =97749e^{0.00002x}

Rounding values to the nearest hundredth, we get

y = 97749e^{x}
