The two-point A and B will be -1+2i and -2+2i respectively.
<h3>What is the complex number?</h3>
A complex number is one that has both a real and an imaginary component, both of which are preceded by the letter I which stands for the square root of -1.
The complex number is given as;
x+iy
Where x is the real part and iy is the imaginary part.
The two points added to obtained -3 + 4i are;
A = -1+2i
B= -2+2i
The sum of the two points is;
⇒A+B;
⇒-1+2i + -2+2 i
⇒-3 + 4 i
Hence the two-point A and B will be -1+2i and -2+2i respectively.

Shop a
Step-by-step explanation:
1.60/4=£0.4 per battery
2.7/6= £0.45 per battery
Hence the batteries at shop a are cheaper
140,000. the hundred is under 5 so you round down
I don’t understand this can you explain please
We have been given a system of nonlinear equations.

In order to solve this system we can first equate the two equations in order to get a quadratic in x.

Our next step is to bring all the terms on one side.

Now we have to solve this equation. We can solve it by factoring using the splitting middle term method.



Upon setting each of these factors equal to zero using zero product property we get

Upon solving both these equations we get

Now we can substitute these values of x in the equation

We get


Therefore, our final set of solutions are
