Answer:

Step-by-step explanation:
Isolate the term of a from one side of the equation.
14/21=a/9
Use cross products.

Solve by a.

<u>a=6</u>
So, the final answer is a=6.
I hope this helps! Let me know if my answer is wrong or not.
Answer:
y = 1/3x

Answer:
3 things :)
Step-by-step explanation:
#1. I have reported these websites to many brainly users and I hope they all stay safe.
#2. As you can see in the model there are 10+ (positives) and -4 (negatives)
and when you subtract the positives and the negatives (10 -4) you would get 6
#3. The equation that represents the model would be when you divide the negative and the positive in this case -4/10 which would equal -2/5
we are given point as
(x,y)=(5,7)
translating 3 units to right side
It means we will subtract 3 to x-value
and we get
(x,y)= (5-3,7)
(x,y)=(2,7)
now, it is reflected about x-axis
so, we can change y-value as -y
so, we get our new point as
(x,y)=(2,-7)
now, we have to find it's image reflection
so, we will get
(x',y')=(-7,2).........Answer
