2x + y = 10
5x - y = 18
7x = 28
x = 4
2(4) + y = 10
8 + y = 10
y = 2
(4,2)
G=38
Whenever you divide or multiply by one the number stays the same, therefore just take out all the xs and then solve the equation. I hope this helps!
Answer:
A
Step-by-step explanation:
In the figure shown, ABC is a right triangle with side lengths a, b, and c, and CD is an altitude to side AB. This altitude divides the triangle into two right triangles ADC and BDC. In these triangles,
So,
![\triangle ABC\sim \triangle CBD\sim \triangle ACD](https://tex.z-dn.net/?f=%5Ctriangle%20ABC%5Csim%20%5Ctriangle%20CBD%5Csim%20%5Ctriangle%20ACD)
1. From the similarity
you have
![\dfrac{AB}{BC}=\dfrac{BC}{BD}\\ \\\dfrac{c}{a}=\dfrac{a}{s}](https://tex.z-dn.net/?f=%5Cdfrac%7BAB%7D%7BBC%7D%3D%5Cdfrac%7BBC%7D%7BBD%7D%5C%5C%20%5C%5C%5Cdfrac%7Bc%7D%7Ba%7D%3D%5Cdfrac%7Ba%7D%7Bs%7D)
2. From the similarity
you have
![\dfrac{AB}{AC}=\dfrac{AC}{AD}\\ \\\dfrac{c}{b}=\dfrac{b}{r}](https://tex.z-dn.net/?f=%5Cdfrac%7BAB%7D%7BAC%7D%3D%5Cdfrac%7BAC%7D%7BAD%7D%5C%5C%20%5C%5C%5Cdfrac%7Bc%7D%7Bb%7D%3D%5Cdfrac%7Bb%7D%7Br%7D)
Hence, option A is true
