Answer:  Age of Brandon is 24 years.

Age of Michael is 72 years.

Step-by-step explanation:

Since we have given that

Michael is 3 times as old as Brandon .

Let the age of Brandon be 'x'.

Let the age of Michael be 3x

According to question, 18 years ago, Michael was 9 times as old as Brandon.

18 years ago,

Age of Brandon was x-18

Age of Michael was 3x-18

So, our equation becomes,

9(x-18)=3x-18\\\\9x-162=3x-18\\\\9x-3x=-18+162\\\\6x=144\\\\x=\frac{144}{6}\\\\x=24

Hence, Age of Brandon is 24 years.

Age of Michael is 24×3=72 years.

9. Complete the reasons in the proof below.
Arada [10]
For a), this is clearly a given as it is literally to the right of where it says “Given:”
For b), since ON bisects ∠JOH, this means that it splits it into two separate angles - JON and HON, which are similar due to that bisects mean that it splits it equally into two halves
For c), since NO is the same thing as NO, it is equal to itself
For d), since AAS (angle-angle-side) congruence states that if there are two angles that are congruent (proved in a) and b) ) as well as that a side is congruent (proved in c) ), two triangles are congruent
For e), since two triangles are congruent, every side must have one side that it matches up to in the other triangle. As the opposite side of angle H is JO and the opposite side of angle J is OH, and ∠J=∠H, those two are congruent. As JN and HN are the two sides left, they must be congruent.

Need help with question 5 please
tatyana61 [14]

Answer:

-1/6

Step-by-step explanation:

To find the slope we use

m = (y2-y1)/(x2-x1)

    = (-4-8)/( 1-3)

    = -12/-2

    =6

We want a line perpendicular, so we need the negative reciprocal

- (1/6)

-1/6
