Answer:
15i^2
Step-by-step explanation:
a negative times a positive is a negative and a negative times a negative is positive
-5×-3=15 and i×i=i^2
X/4 + b/4
i need some values tho
Given:
The equations are


To find:
Which function is changing more quickly.
Solution:
The slope intercept form of a line is

Where m is slope and b is y-intercept.
On comparing
with the slope intercept form, we get



On comparing
with the slope intercept form, we get


Since,
, it means the absolute rate of change of second function is greater than the first function.
Therefore, the second function is changing more quickly.
4(2x-7)=8x-28
4(-4x+18)=-16x+72
(8x-28)-(-16x+73)
24x+45
The matrix should be this:
