Answer: A = 20
How to Solve:
Just by looking at this problem I can tell that the denominators (9 an 45) are factors of 9. So the second equation is multiplied by 5 from the first equation.
4/9 x 5
4 x 5 = 20
— -—
9 x 5 = 45
So A would be 20.
Another way to solve this would be by multiplying the 1st equations numerator with the second equations denominator:
4 x 45 = 180
Then divide 180 with the 1st equation’s denominator.
180 / 9 = 20
A = 20
Answer:
s = -4 ± √31
Step-by-step explanation:
Given 4
+ 32s = 60
divide by 4 throughout
![s^{2} + 8s = 15\\s^{2} + 8s + (\frac{8}{2}) ^{2} = 15 + (\frac{8}{2}) ^{2}](https://tex.z-dn.net/?f=s%5E%7B2%7D%20%20%2B%208s%20%3D%2015%5C%5Cs%5E%7B2%7D%20%2B%208s%20%2B%20%28%5Cfrac%7B8%7D%7B2%7D%29%20%5E%7B2%7D%20%20%3D%2015%20%2B%20%28%5Cfrac%7B8%7D%7B2%7D%29%20%5E%7B2%7D)

Answer:
The answer in the procedure
Step-by-step explanation:
we have the right triangle ABC
The pre-image coordinates are
![A(0,0),B(0,3),C(4,0)](https://tex.z-dn.net/?f=A%280%2C0%29%2CB%280%2C3%29%2CC%284%2C0%29)
The transformation to use is the translation
The rule of the translation is
![(x,y)-----> (x+10,y)](https://tex.z-dn.net/?f=%28x%2Cy%29-----%3E%20%28x%2B10%2Cy%29)
That means----> The translation is 10 units to the right
The image coordinates are
Applying the rule of the translation
![A'(0+10,0)=A'(10,0)](https://tex.z-dn.net/?f=A%27%280%2B10%2C0%29%3DA%27%2810%2C0%29)
![B'(0+10,3)=B'(10,3)](https://tex.z-dn.net/?f=B%27%280%2B10%2C3%29%3DB%27%2810%2C3%29)
