Answer:
the correct answer is 2/7
of the function y = f(x) definded by x²+xy-y2 = 4.
Answer:
2x + y
Step-by-step explanation:
x² + xy - y² = 4
→ Remember the rule, bring the power down then minus 1
2x + y
The equation becomes 4610 = 2115, which is not true.
Let's break down the given equation and the steps to solve it step by step:
Given the equation: 47 × 98
Step 1: Express 98 as a combination of (47)'s and (2)'s. (98) can be written as (47 × 2).
Step 2: Substitute the expression for 98 in terms of 47 and 2 back into the equation:
47 × 98 = (47 × 47) - (2 × 47)
Step 3: Calculate the values on both sides of the equation.
- The left side: 47 × 98 = 4610.
- The right side:
- 47 × 47 = 2209
- 2 × 47 = 94
- Subtracting 94 from 2209 gives 2115.
Explanation:
1. We start with the equation 47 × 98, where 98 is represented as 47 × 2.
2. We substitute 98 in terms of 47 and 2 to get (47 × 47) - (2 × 47).
3. We calculate the values on both sides of the equation to find that they don't match. This indicates that the original equation is not true.

Answer:
The answer to your question is:
2 and -49
Step-by-step explanation:
2 x -49 = -98
2 + (-49) = -47
x2 - 47x - 98 = 0
The solution to factor the quadratic equation above is:
(X + 2 ) (X - 49)
Since 2 and -49 multiply to -98 and add up -47, you know that the following is true:
x2 - 47x - 98 = (X + 2 ) (X - 49)

Answer:
The pythagoras's theorem is the relation between the sides of a right-angles triangle, it shows that the square of the hypotenuse of the triangle will be equal to the sum of squares of the remaining sides
hypotenuse² = perpendicular² + base²
replacing the variables with the sides of the given triangle:
x² = 15² + 8²
x² = 225 + 64
x² = 289
x = √289
x = 17 mi
