![\large\boxed{a-b=11}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7Ba-b%3D11%7D)
Step-by-step explanation:
![\text{Use}\ x^2-y^2=(x-y)(x+y).\\\\\text{We have}\\\\a^2-b^2=275\ \text{and}\ a+b=25.\\\\\text{Substitute:}\\\\275=(a-b)(25)\qquad\text{divide both sides by 25}\\\\\dfrac{(a-b)(25)}{25}=\dfrac{275}{25}\\\\\boxed{a-b=11}](https://tex.z-dn.net/?f=%5Ctext%7BUse%7D%5C%20x%5E2-y%5E2%3D%28x-y%29%28x%2By%29.%5C%5C%5C%5C%5Ctext%7BWe%20have%7D%5C%5C%5C%5Ca%5E2-b%5E2%3D275%5C%20%5Ctext%7Band%7D%5C%20a%2Bb%3D25.%5C%5C%5C%5C%5Ctext%7BSubstitute%3A%7D%5C%5C%5C%5C275%3D%28a-b%29%2825%29%5Cqquad%5Ctext%7Bdivide%20both%20sides%20by%2025%7D%5C%5C%5C%5C%5Cdfrac%7B%28a-b%29%2825%29%7D%7B25%7D%3D%5Cdfrac%7B275%7D%7B25%7D%5C%5C%5C%5C%5Cboxed%7Ba-b%3D11%7D)
Answer:
Step-by-step explanation:
Domain: ℝ
Range: [-3, ∞)
When x<4, the graph is decreasing.
When x>4, the graph is increasing.
Vertex (4, -3)
Answer:
Step-by-step explanation:
1. These angles are complementary, which means that they add up to 90 degrees.
x + 73 = 90
x = 17 degrees
2. These angles are supplementary, which means that they add up to 180 degrees.
x + 118 = 180
x = 62 degrees
