Given: AZ = 3 cm, ZC = 2 cm, MC = 5 cm, BM=3 cm. Find:

the ratio of areas AXY: AYZ

Here is the correct question.

Given: AZ = 3 cm, ZC = 2 cm, MC = 5 cm, BM=3 cm. Find:

the ratio of areas XY: YZ

XY : YZ = 1.8 : 3

Step-by-step explanation

From the diagram below:

Line XZ is parallel  to Line BC

i.e

This is typically and isosceles triangle with a triangle and a parallelogram embedded in it.

So; to solve for XY and YZ; we have

= =

Let's first solve for XY :

=

3 × 3 = 5(XY)

9 = 5(XY)

XY =

XY  = 1.8

From XY = 1.8

we have:

3(YZ) =5 × 1.8

YZ =

YZ = 3

∴ XY: YZ

= 1.8 : 3

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)

answer: 91
