(b) because when you change 215% into a decimal it’s 2.15 then multiply that by 50 you get 170.5 and you move the decimal to get 1.705 so it’s b
An exponential function is expressed in the form y=axb^x. The relation represents a growth when b>1 and a decay when 0<b<1.
Have a great day! Hope this helps!
Answer:
I really don't know , I am in 7th grade
8 5/7+- 7 4/7
=69/8+(-53/7)
=7 * (times the numerator and denominator) (69/8) - 8* (same here)(53/7)
=483/56- 424/56
=59/56
