X^2 + X -420 = 0
X = 20
Step-by-step explanation:
Answer:
0.531 > 0.456
0.63 > 0.47
0.267 < 0.539
0.07 < 0.7
Step-by-step explanation:
a. 0.531 _____ 0.456
compare the numbers from left to right
5 is greater than 4 so 0.531 greater than 0.456
0.531 > 0.456
b. 0.63 _____ 0.47
6 is greater than 4. 0.63 > 0.47
c. 0.267 _____ 0.539
2 is less than 5 . so 0.267 less than 0.539
0.267 < 0.539
d. 0.07 _____ 0.7
0 is less than 7
0.07 < 0.7
It's C.
The value is increasing threefold relative to the previous step.
all other function values increase by a fixed amount and are therefore linear
