Answer: -66

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

use PEMDAS.  Evaluate the parentheses, then multiplication, then addition.

-3[-3(-4 - 1) - (-3 - 4)]

           ↓           ↓

-3[-3(  -5  ) - (   -7   )]

       ↓          ↓

-3[   15     +    7      ]

               ↓

-3[           22          ]

  ↓

-66

A Canadian television station shows 16 minutes of commercials every hour between 8:00 a.m. and 11:00 p.m. every day.
valentinak56 [21]

There are 16 minutes of commercials per hour from 8 A.M to 11 P.M

First, we have to find out how many hours is 8 A.M to 11 P.M

The hours are: 8, 9, 10, 11, 12, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and 11.

So, it is 16 hours from 8 A.M to 11 P.M

Then, we multiply multiply 16 by 16 to find out how many minutes of commercials are in 16 hours.

16 x 16 = 256

So, there is 256 minutes of commercials in 16 hours.

Lastly, multiply 256 by 365 to see how many minutes of commercials are in one year.

256 x 365 = 93,440

Therefore, there are 93,440 minutes of commercials in a year.

2. Perpendicular to y=1/3X-5 and goes through the point (3, -5)
Rudiy27

Answer:

Step-by-step explanation:

To be perpendicular the product of the two slopes is equal to negative one.

m1(m2)=-1, in this case the slope of the reference line is 1/3 so the other line will have a slope

m/3=-1

m=-3 so our perpendicular line is

y=-3x+b, using point (3,-5) we can solve for the y intercept b

-5=-3(3)+b

-5=-9+b

b=4 so the completed perpendicular line passing through point (3,-5) is

y=-3x+4
