The skier would have to go skiing 15 days im pretty sure.
hope im right :)
Solve for x over the real numbers:
x^2 = 49
Take the square root of both sides:
Answer: x = 7 or x = -7
The answer is 42 because 14x3 is 42
N=7/5=1.4 because if you divide by 5 your answer should be 1.4
Answer:
3. Option 2 (Perpendicular)
4. Option 3 (neither)
Step-by-step explanation:
3.
m1 = -7/8
Second equation: -8x + 7y = -21
7y = 8x - 21 y = (8/7)x - 3
m2 = 8/7
m1 & m2 are not equal, so not parallel
Since m1×m2 = (-7/8)(8/7) = -1,
They are Perpendicular
4.
m1 = -1/4
Second equation: -2x + 8y = 6
8y = 2x + 6 y = (1/4)x + 3/4
m2 = 1/4
m1 & m2 are not equal, so not parallel
Since m1×m2 = (-1/4)(1/4) = -1/16, not -1. They are not Perpendicular either. So, neither
