Answer:
The relation which is a function is the one in which none of the first coordinates repeated.
Step-by-step explanation:
5/(x^2-4)+2/x=2/(x-2) if we factor the leading denominator, it is a "difference of squares" of the form (a^2-b^2) which always factors to (a-b)(a+b) so we have:
5/((x-2)(x+2))+2/x=2/(x-2), to add/subtract fractions we need a common denominator, so in this case we need a common denominator of x(x-2)(x+2) so
5(x)+2(x+2)(x-2)=2(x)(x+2), perform indicated operations...
5x+2(x^2-4)=2x(x+2)
5x+2x^2-8=2x^2+4x subtract 2x from both sides
5x-8=4x subtract 4x from both sides
x-8=0 add 8 to both sides
x=8
check...
5/(x^2-4)+2/x=2/(x-2) when x=8 so
5/(64-4)+2/8=2/(8-2)
5/60+1/4=2/6
5/60+15/60=20/60
20/60=20/60
1 gram = 0.00220462 pound
Convert:
0.00220462 × 800 = 1.7637
800 grams = 1.7637 pounds
Answer:
1/2

Answer:
all angles will be 200, 50 , 40 and 70 - hope this helped :)
Step-by-step explanation:
everything equals to 360 after added together
360 - 250 = 110
110 divided by 11 = 10
4:7 (x 10)
40:70
the other angels will be 40 and 70
