Equations:
x + y = 26
x - y = 4
---
Add to get:
2x = 30
x = 15

Solve for "y":
x + y = 26
15 + y = 26
y = 11 (smaller number)
Answer:
f(4)=-2
Step-by-step explanation:
f(4)=-4+2=-2
From the equation
![{x}^{2} - 10x + 25 = 0](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20-%2010x%20%2B%2025%20%3D%200)
We can see that 25 is 5 × 5, and 10 is 5 + 5, so the equation simplifies to
![(x - 5)(x - 5) = 0 \\ {(x - 5)}^{2} = 0](https://tex.z-dn.net/?f=%28x%20-%205%29%28x%20-%205%29%20%3D%200%20%5C%5C%20%20%7B%28x%20-%205%29%7D%5E%7B2%7D%20%20%3D%200)
which then we use to set each parentheses to equal 0
![(x - 5) = 0 \\ x = 5](https://tex.z-dn.net/?f=%28x%20-%205%29%20%3D%200%20%5C%5C%20x%20%3D%205)
Since both parentheses are the same, there is only one solution: C. 1 real number solution
Answer:
I dont understand ur question
Answer:
5, and 20
Step-by-step explanation:
5+20=25
reciprocal of 5 is 1/5 and reciprocal of 20 is 1/20 so 1/5=4/20 and 4/20 + 1/20 = 5/20. 5/20 = 1/4
