Triangle GCH is similar to triangle DCE. Find CH
soldier1979 [14.2K]

Answer:

x = 65

Step-by-step explanation:

if two triangles are similar then we can use the similarity ratio to find the length of CH

60/156 = x/169 cross multiply expressions

156x = 10140 divide both sides by 156

x = 65

What point on the graph of y = 0.5f(x) corresponds to (4, 16)? Explain.
SVETLANKA909090 [29]

We are given a coordinate (4,16).

Where first coordinate is the value of x and second coordinate is the value of y for the function y=f(x).

We need to find the value of given point (4,16) for function y= 0.5f(x).

Here function f(x) is being multiplied by 0.5.

On multiplying 0.5 by y, it will effect the value of y only. It does not effect value of  x . Because x value is still x. Only function f(x) is being multiplied by 0.5.

Therefore, y= 0.5f(4) = 0.5 * 16 = 8.

So, (4,8) is the point on the graph of y = 0.5f(x) corresponds to (4, 16).

Find the midpoint of the segment with the given endpoints. ​(9​,9​) and ​(-1​,- 3​)
GenaCL600 [577]

Answer: (4, 3)

Step-by-step explanation:

The formula for coordinate of the mid point is given as :

Mid point = (\frac{x_{2}+x_{1}}{2} , \frac{y_{2}+y_{1}}{2} )

x_{1} = 9

x_{2} = -1

y_{1} = 9

y_{2} = -3

Substituting the values into the formula , we have :

Mid-point = (\frac{-1+9}{2} , \frac{-3+9}{2} )

Mid-point = ( \frac{8}{2} , \frac{6}{2} )

Mid - point = ( 4 , 3)
