Use distributive property to simplify -(x+3y-z)

Mathematics
1 answer:
UkoKoshka [18]3 years ago
4 0

Answer:

-x - 3y + z

Step-by-step explanation:

Think of a imaginary 1(-1 because of the sign) in front of the parenthesis and distribute it to the other number and so x will become -x, 3y will become -3y and -z will become z because two negatives make a positive.

Verizon [17]

Answer:

The 22nd Term is -77.

Step-by-step explanation:

The pattern is -5.  If you subtract 5 from each starting number you'll get the following number.

Ex:  28 - 23 = 5

      23 - 18  = 5

       18 - 13  = 5

Subtract 5, 22 times and you will get -77.

Answer:a. [tex] $f\propto  L$ [\tex]

b. [tex] f \propto \sqrt{T} [\tex]

c. [tex] f \propto \frac{1}{\sqrt{P}} [\tex]

I. Decrease in length increases leads to increase in pitch.

II. Increase in tension leads to increase in pitch.

III. Increase in linear density reduces the pitch

Step-by-step explanation: I. Since the frequency is inversely proportional to the length increase in length leads to decrease in frequency likewise decrease in length leads to increase in frequency.

II. Since the frequency is directly proportional to the square root of the tension increase in tension leads to increase in frequency likewise decrease in tension leads to decrease in frequency.

III.since the frequency is inversely proportional to the square root of the linear density so increase in linear density leads to decrease in frequency and likewise decrease in linear density leads to increase in frequency.
