Answer:
536
Step-by-step explanation:
To find how many red gumballs where put into the machine: 253-98 = 155
To find how many blue gumballs where put into the machine: 155- 27 = 128
To then find the total amont of gumballs placed into the machine:
253+155+128 = 536 gumballs where placed into the machine in total
The domain of a function contains the x-values of the function while the range of the function contains the y-values of the function. In this case, we substitute 25 and 64 to y. Then,
25 = k2 + 2 k + 1 (k-4) * (k+6) = 0
64 = k2 + 2 k + 1 (k-7) * (k+9) = 0
hence the domain is {-9,-6, 4,7}
