5(20) + 4y = 216
100 + 4y = 216
4y = 216 - 100
4y = 116
y = 116/4
y = 29.....so they sold 29 four-dollar yogurts + 20 five-dollar yogurts....for a total of 49 yogurts sold <==
In order for the whole expression to be negative, either (x⁵)
or (y⁴) or (z²) must be negative.
But an even-numbered power can't be negative ... even if the base
is a negative number, any even-numbered power of it is positive.
So (y⁴) and (z²) are always positive. The expression can be
negative if 'x' is negative, because (x⁵) will then be negative.
None of the proposed requirements is appropriate, so the
final answer is E. None .

Step-by-step explanation:
Answer:
45 %
Step-by-step explanation:
8 - 20 will get you across IF it is NOT a prime
primes in this range are 11 13 17 19
8-20 is 13 chances minus the four primes leaves 9 rolls out of a possible 20 rolls that will get you across
9/20 = 45%
(x,y)
if x repeats with a differnt y then it is not a function
A. none of them repeat, it's a function
B. none of them repeat, it's a function
both of them are functions
