Answer:
Step-by-step explanation:
Add 1 and subtract 1, so that the expression won't change.
(a² - b²) = (a+b)(a - b)
Here a = x² - (1/x²) and b = 1
![= [ (x^{2}-\frac{1}{x^{2}})+ 1 ] [ (x^{2} -\frac{1}{x^{2}} - 1 ]](https://tex.z-dn.net/?f=%3D%20%5B%20%28x%5E%7B2%7D-%5Cfrac%7B1%7D%7Bx%5E%7B2%7D%7D%29%2B%201%20%5D%20%5B%20%28x%5E%7B2%7D%20-%5Cfrac%7B1%7D%7Bx%5E%7B2%7D%7D%20-%201%20%5D)
Answer:
y= -1/2x + 3
Step-by-step explanation:
A line perpendicular will have the reciprocal slope.
First you need to find the slope of the line given.
m= rise/ run
m= -2
Now flip for the reciprocal.
The perpendicular line will have a slope of -1/2
Answer:
I beleive the answer is $9000
Step-by-step explanation: What is 18% of 50000?
Y is 18% of 50000
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 18% * 50000
Converting percent to decimal:
p = 18%/100 = 0.18
Y = 0.18 * 50000
Y = 9000
Answer:
6 pounds and 15 ounces
Step-by-step explanation:
Since 1 pound is equal to 16 ounces you divide 111 by 16 and get 6 remainder 15 which is basically 6 pounds and 15 ounces. Hope this helps!
Answer:
15
Step-by-step explanation:
Rate of change or slope or gradient of a line passes two points (x1, y1) and (x2, y2) could be calculated by:
(y2 - y1)/(x2 - x1)
=> Rate of change of the line passing (1,15) and (3,45):
(45 - 15)/(3 - 1) = 30/2 = 15
