Answer:
The slope of the line would be 1
Step-by-step explanation:
To do this, you would take the slope formula, (Y2-Y1)/(X2-X1)
Next we would plug in the points of the line
(13-8)/(8-3)
5/5
1/1
Therefore, the slope of the line is 1.
Answer: 1 out of 5 for the first box and 1 out of 7 for the second box
( in simplest form)
Step-by-step explanation:
Recall that (a + b)² = a² + 2ab + b².
Let a = x² and b = y². Then
(x² + y²)² = (x²)² + 2x²y² + (y²)²
⇒ x⁴ + y⁴ = (x² + y²)² - 2 (xy)²
Given that x² + y² = 13 and xy = 6, we have
x⁴ + y⁴ = 13² - 2×6² = 97
