Answer:

x = -4

x = -11/9 = -1.222

Step-by-step explanation:

(6−i)(−7−9i)

= -42 - 54i +7i + 9i^2

= -42 - 47i + 9i^2

x = -4

x = -11/9 = -1.222

brainliest please :)

If gumballs cost 150 a bag ,and there 15!gumballs in each bag much do you need to charge for each gumball in order to make money

pshichka [43]

More than 10 a gumball.

150 divided by 15 is 10, which would be the price you bought for. If you want to make more money, you must at least have a surge pricing of 10 unit prices per gumball.

What is the inverse function of y=x^2-7

Vikentia [17]

With inverse functions you just swap 'x' and 'y' and solve for 'y'.

$\sf y=x^2-7$

Swap 'x' and 'y':

$\sf x=y^2-7$

Add 7 to both sides:

$\sf x+7=y^2$

Take the square root of both sides:

$\sf y=\boxed{\sf\pm\sqrt{x+7}}$
