Mathematics
1 answer:
Alisiya [41]3 years ago

Answer:

y= –1/x

Step-by-step explanation:

Perpendicular = gradients are the inverse of each other or in other words, gradient 1×gradient 2 = –1

Examples of perpendicular gradients:

2 and –1/2

2/4 and -4/2

When inversing a number:

Change the sign (– to +/ + to –)

Swap the numerator with the denominator (1/2 becomes 2/1, or simply 2)

Okay so here are the steps....

(5 + 2i) + (8 - 3i)       <---- when we have exponents we should worry about the                                            "i" because it is equal to √-1 but here it isn't the case.
<u>

(13 - i)</u>
<u />   <----- This is the answer!
