Answer:
Step-by-step explanation:
4y2 - 2x + 7 + 2y for x = 7 and y =2.
= 4(2)^2 -2(7) +7 + 2(2)
= 4(4) - 14 +7 + 4
= 16 - 14 + 7 + 4
= 13
104 = -16t^2 + 729
16t^2 = 729 - 104 = 625
t^2 = 625/16 = 39.0625
t = sqrt(39.0625) = 6.25
Answer= t > 6.25

Answer:
all real number greater than or equal to 2
Step-by-step explanation:
The range is the y value so that is 2 and the y values are increasing because the graph is increasing. It is greater than or equal to 2 because it has a closed dot which stands for greater than or equal to.
