Answer:

(0,5)

Step-by-step explanation:

Just plug them in:

2x - y = 10

- 2 (0) - (5) = 10?

no because 2 x 0 is 0. That would mean -5 = 10. which isn't true

- 2 (10) - (10)?

yes because 2 x 10 is 20. Subtract 10 from that and you get 10. so 10 =10

- 2 (5) - (0)?

yes because 2 x 5 is 10. There is nothing to subtract from 10 so you get 10. 10 =10.

TRUE OR FALSE: FOR ANY FUNCTION, X=F^-1(Y), THEN Y=F(X). PLEASE EXPLAIN
Vesnalui [34]

Answer:

True.

Step-by-step explanation:

For example let f(x) = 3x + 1  then f-1(x)  is found as follows

Let f(x) = y = 3x + 1 then

3x = y - 1

x = (y-1) / 3

x = f-1(x) = (x - 1)/3.

So:

Replacing the x  in y by (x - 1)/3 :-

x = f(-1)(y) = ( (3x + 1) - 1) / 3

= 3x / 3

= x.

So y = f(x).

5x + (1x+6)= 78<br> BARDZO POTRZEBUJĘ
kifflom [539]

Answer:   x = 12

Step-by-step explanation:  

1. add 5x + 1x which will equal 6x so now your equation is:  6x + 6 = 78

2. subtract 6 from 78 to get 72:  6x = 72

3. divide 72 by 6x to get your answer 12

5: Answer the questions completely: Jordan has a new puppy. She wants to put a fence around part of her yard to cover an area of
irga5000 [103]

Given that Jordan has a new puppy and she wants to put a fence around part of her yard to cover an area of 200 square feet.

Now we have to find what dimensions (length x width) should she make the rectangular area. None of the length or width are given so there can be lots of answers.

Since area is rectangular and we know that rectangle has different value of length and width so we just need to find two factors of given area 200 square feet.

For example 20 times 10 is 200.


So the dimension of the rectangular area will be:

Length = 20 feet and width = 10 feet


Now perimeter of the rectangle is given by formula:

Perimeter = 2(length+width) = 2(20+10)=2(30)=60


Hence perimeter is 60 feet.

Can you subtract closed polynomials
netineya [11]

Answer:

Polynomials are closed under addition. When subtracting polynomials, the variables and their exponents do not change. Only their coefficients will possibly change. This guarantees that the difference has variables and exponents which are already classified as belonging to polynomials.
