The answer is -16 - 10i.
Using the distributive property on the first part, we have:
-2i*7--2i*4i + (3+i)(-2+2i)
-14i+8i² +(3+i)(-2+2i)
Using FOIL on the last part,
-14i+8i²+(3*-2+3*2i+i*-2+i*2i)
-14i+8i²-6+6i-2i+2i²
-10i+8i²-6+2i²
Since we know that i = -1,
-10i+8(-1)-6+2(-1)
-10i-8-6-2
-16-10i
Part A.
We could take, for example:
For x ≥ -3 we have vertical line (x-intercept = -3) and shaded region on the right side of the line.
For y ≥ 3 we have horizontal line (y-intercept = 3) and shaded region above that line.
Part B.
Simply, substitute x and y coordinates of D and E <span>to the system of inequalities from part A, and check if its is true, what we get.
</span>
so point D is a solution,
and point E is also a solution to <span>our system of inequalities.
</span>
Part C.
There are two ways we could do that. First is the same as in part B. We substitute x and y coordinates of each school and check if inequality is true or false:
So Timothy can attend schools C and F.
We can also draw a graph of that inequality (pic 2).
Answer:
if its without replacement then idk but if its with replacement then 1/8
Step-by-step explanation:
Answer:
15=x 5x=75
Step-by-step explanation:
90/6=15
6 is how many x's there are in total meaning that 1 x = 15
15*5=75 so one angle is 15 while the other is 75
75 + 15= 90
90+90=180 getting you the 180 degrees
