Answer:
The solution of the system is x=-1, y=-2
Step-by-step explanation:
we have
----> equation A
----> equation B
Solve the system by graphing
Remember that the solution of the system is the intersection point both lines
using a graphing tool
The intersection point is (-1,-2)
see the attached figure
therefore
The solution of the system is x=-1, y=-2
Answer:
The relation is discrete function
Domain is {x|x = 2,2,2}
Range is {y|y = 4, -1, -3}
Step-by-step explanation:
I. This function is discrete because x = 2,2,2
and y = 4, -1, -3
Or (2,4), (2,-1) and (2,-3)
If this function is continuous, the x and y will be something like this -3 <= x <= 3
II. Domain is x.value
III. Range is y.value

<span>Answer: 39 quarter
The value of a stock share in a new technology company has been increasing at a rate of 8.6% quarterly. That means the stock will increase by 8.6%/4= 2.15% rate per quarter. The exponent function to find the number of money the investor have would be:
</span>an= $102.15(1.0215)^t
<span>
The time needed for getting </span>$233.10 would be:
an= $102.15(1.0215)^t
$233.10= $102.15(1.0215)^t
2.2819 * $102.15= $102.15( 1.0215)^t
2.2819 = (1.0215)^t
t= log1.0215 2.2819
t= 39
