Answer:
F(x) = 1/x^2
Step-by-step explanation:
F(x) = 1/x^2 is
y = 1/x^2
graph goes up to 10 each side
plug in 1,2,3,4,5,6,7,8,9,10 for x and see what y looks like
when x is 1,2,3,4,5,6,7,8,9,10
y is 1,1/4,1/9,etc
8 is 91 because 13•7 is 91 inside is needed 91 tiles
Answer:
-7 - 2 = -9 (combine the numbers,simplify)
12 + (-4) = 8 (Simplify the Expression)
-8(-6) = 48 (Simplify the Expression)
18/-3 = -6 ( Simplify the Expression)
Hope this helps :)
Answer: 5x - 2y = 8
y+1=5/2(x-2)+2
multiply the each side by 2 to get rid of the fraction
2 (y+1) = (5/2 (x-2) +2 )2
2y+2=5(x-2)+4
now distribute the 5
2y+2=5x-10+4
subtract the two from each side
2y=5x-10+4-2
add like terms
2y=5x-8
subtract 5x from each side
2y-5x=-8
multiple the whole equation by -1 to make the 5x a positive
-2y+5x=8
hope this helps!
Answer:
-7/8
Step-by-step explanation:
- 2 5/8 * 1/3
Change the mixed number to an improper fraction
2 5/8 = (8*2+5)/8 = 21/8
-21/8 *1/3 = -7/8
