<u>Step-by-step explanation:</u>

$\sqrt{100} + \sqrt{-81}$

$\sqrt{100} = 10$
$\sqrt{-81} = \sqrt{-1} * \sqrt{81} = i * 9 = 9i$

$\sqrt{100} + \sqrt{-81}$

= 10 + 9i

Answer:

i think the answer would be C

Step-by-step explanation:

since it seemed you had to divide the numbers a hundred would turn into ten and ninety would turn into nine and because you have one negative and one positive that means it would have to be a negative so it would be

10 - 9i

PLSS HELPP WILL GIVE BRAINLIEST PLS ANSWER ALL 3

podryga [215]

Answer:

$\large \boxed{\sf non \ linear, \ non \ linear, \ linear, \ linear}$

Step-by-step explanation:

Write the equations in the form y = mx + b

If the equation contains exponents then it is non-linear, if not then it is linear.

2xy = 3

This graph forms a curve so it is non-linear

y = 1x³ + 5

This equation is non-linear because it contains an exponent

y = x/3

y = 1/3x + 0

This equation is linear ( no exponent(s) )

2y = 1/2x

y = 1/4x + 0

This equation is linear ( no exponent(s) )
