How to solve -3z+1=7

Mathematics

Alenkasestr [34]3 years ago

Answer:  z = -2

Step-by-step explanation:

The goal is to get the variable "z" alone, so we have to simplify it. You subtract 1 from each side, making the left side read "-3z" and the right simply have 6. You then have to get rid of the coefficient, which is the number that your variable (z) is being multiplied by. So you then divide each side by -3. You will be left with "z = -2" because 6 divided by -3 is equal to -2.

Can you help with this one too.
lidiya [134]

Answer:

Odd, Even

Step-by-step explanation:

A function is said to be an Even function if it follows f(-x) = f(x).

A function is said to be an Odd function if it follows f(-x) = -f(x).

It means we can plug -x in place of x and check if it comes out to be f(x) or -f(x) i.e. y or -y?

Given y = sin³x/cos³x and y = 1/sec³x

y = sin^3x/cos^3x\\f(x) = sin^3x/cos^3x\\f(-x) = sin^3(-x)/cos^3(-x)\\f(-x)= (sin(-x))^3/(cos(-x))^3\\f(-x)=(-sin(x))^3/(cos(x))^3\\f(-x)=-sin^3x/cos^3x\\f(-x)=-f(x)\\Odd\; function

y=1/sec^3x\\f(x)= 1/sec^3x\\f(x)=cos^3x\\f(-x)=cos^3(-x)\\f(-x)=(cos(-x))^3\\f(-x)=(cos\;x)^3\\f(-x)=cos^3x\\f(-x)=f(x)\\Even\; function

Hence, first function is Odd, second function is Even.

HELP:How many ways can four
Tju [1.3M]

Answer:

24 ways.

Step-by-step explanation:

In this case, you just need a factorial.

For the first seat, you have 4 students you can place.

For the second seat, you have 3 students.

For the third, you have 2.

For the fourth, you have 1.

So, you can arrange the students by doing 4 * 3 * 2 * 1 = 12 * 2 = 24 ways.

Hope this helps!
