Answer:

8m-5

Step-by-step explanation:

Lets write this out in an equation.The plus means addition and the minus means subtraction.

6m+2m-5

Since there is two things with the same variable we can combine them.

8m-5

That is as simple as it gets.

6m plus 2m minus 5

If you turn that into an algebraic expression, it would look something like this:

6m + 2m - 5

Now, you combine like terms.

6m + 2m - 5 = 8m + 5.

Solve for y, 12x-20y=180

nydimaria [60]

Answer:

y=35x−9

Step-by-step explanation:

Step 1: Add -12x to both sides.

12x−20y+−12x=180+−12x

−20y=−12x+180

Step 2: Divide both sides by -20.

−20y−20=−12x+180−20

y=35x−9

Prove the identity (sina-cosatanb)/(cosa+sinatanb) = tan (a+b)

OLga [1]

Sina - (cosa)(tanb)/cosa + (sina)(tanb)
sina ≡ (tana)(cosa)

(tana)(cosa) - (cosa)(tanb)/cosa + (tana)(cosa)(tanb)
= cosa(tana - tanb)/cosa(1 + tanatanb)
(cosas cancel out)
= (tana - tanb)/(1 + tanatanb) ≡ tan(a-b)

State which of the following sets of ordered pairs represent a function.

anastassius [24]

Answer:

d. Set A and Set B

Step-by-step explanation:

We have been given three sets:

Set A: (5, 2), (4, 3), (3, 4), (2, 5)

Set B: (-1, -6), (0, 2), (1, 2), (3, 6)

Set C: (2, 1), (4, 2), (2, 3), (8, 4)

Now we need to state about which of the following sets of ordered pairs represent a function.

We know that a function can't have repeated values in domain that is x-value can't repeat.

we see that set C has repeated x-value "2".

Then set C is not a function.

Hence correct choice is:

d. Set A and Set B

What are the solutions of the equation x2=16/25

Margarita [4]

Answer:

8/25

Step-by-step explanation:

8/25 • 2/1 = 16/25. To work this backward, you need to know that any whole number can be converted into a fraction by putting the number over one. 2 = 2/1. divide 16 by 2 and you get 8, and that 8 goes over 25. Then, set up your equation. 2/1 • 8/25 = 16/25.
