Answer:
A
Step-by-step explanation:
x2 = -98
x =+-√-98
x = +-√49 • 2 • -1
x = +-7√2 • -1
x = +-7i√2
(Note: i = √-1 and i^2 = -1, so you can interchange the values)
Answer:
There were 2 expressions I thought of it could be 10 x 5 or 10 + 10 + 10 + 10 + 10. I honestly hope this is the right answer because i'm only in 6th grade but hopefully it's correct.
Step-by-step explanation:
f(x) = x² + 7x + 10
f(0) = (0)² + 7(0) + 10 = 10 ----> (0, 10)
f(2) = (2)² + 7(2) + 10 = 28 -----> (2, 28)
rate of change is slope:

= 9
Answer: 9
(I know there isnt any real problem here to solve, but heres a tip on how to solve greatest to least with decimal problems)
1. Just because a number looks big, doesn't mean it is big
Example: 1.00000000000001 < 1.1
just look at the numbers ^ and dont just hastily read it over assuming that 1.1 is smaller because it "has less digits"
2. Negative numbers are... opposite. and they are less than positive numbers
-3.4 > -4.1
Why is this? Well, if you look on a line, with the point 0 in the middle, you can see that -3.4 is not as far away from 0 as -4.1 is. So the idea is to apply opposite logic for negative numbers
I hope these tips helped!! :D
