(I am using
in place of conj(z)

Question (19):
Answer: (B) -7
modulus of -7 is sqrt(49)=7
the other choices are all < 7
Answer:

Step-by-step explanation:
The point is located in Quadrant II of the graph, where x-values are negative and y-values are positive.
Each marking on the graph represents one unit of distance. The two <em>axes</em> meet at the origin, where the coordinate point is equal to
.
So, you can count backwards once from the origin to get your x-value ⇒
and count up upwards four times from
to get your y-value ⇒
.
Finally, place these in a coordinate point
⇒
.
Answer:
The solution of the system is the ordered pair (-13,-4)
Step-by-step explanation:
we have
-----> equation A
----> equation B
Solve the system by elimination
Multiply by 2 both sides equation B
----> equation C
Adds equation A and equation C

<em>Find the value of a</em>
substitute the value of b in any equation (i take equation B)



therefore
The solution of the system is the ordered pair (-13,-4)
Little late, but your answer would be 133 pieces of candy corn.
Best of luck.
