Answer: B = 64
Step-by-step explanation:
To find B, we need to perform reverse operations. First, add 1 back to 15, which gives us 16. 16*4=64, which means that B must be equal to 64.
Both the numerator and denominator have a 9 and a "b" in common, so we can reduce the fraction to:
3c/4d
(x,y)
sub those for x and y and see if you get a true statement
(2,-8)
6(2)+-8=-4
12-8=-4
4=-4
fasle
(2,8)
6(2)+8=4
12+8=4
20=4
false
(1,2)
6(1)+2=4
4+2=4
6=4
false
(1,-10)
6(1)+-10=4
6-10=-4
-4=-4
true
