Classify the equation as having one solution, infinitely many solutions or no

Mathematics
1 answer:
ICE Princess25 [194]2 years ago
4 0

Answer:

No solutions

Step-by-step explanation:

Simplify both sides of the equation as much as possible:

9r + 5 - 4 = 4r + 5r - 12

9r + 1 = 9r - 12

Both sides have "9r" which when cancel out, leave the equation as:

+1 = -12

This means there are no solutions.

(-19+7i)-(29+32i)=<br><br> in the form (a+bi)
olga_2 [115]
ANSWER

-48-25i

EXPLANATION

We want to simplify the expression,

(-19+7i) - (29+32i)

Let us expand the bracket to obtain,

-19+7i-29-32i

We now group the complex number parts and real number parts.

-19 -29+7i-32i


We simplify further to obtain,

- 48-25i


This is in the form,

a+bi

where

a=-48

and

b=-25
