The domain is the x coordinate, and the range is the y coordinate. You just have to list them EX; (4,0), (6,7) (4,9)
Domain. Range.

Factorise the following expression using grouping and use binomial products to simplify.
rewona [7]

Answer:

11x-55-5a+ax

11(x-5)+a(x-5)

(11+a)(x-5)

Step-by-step explanation:

First you factor out the common factors

for(11x-55) is would be 11 as both of these figures are the multiple of 11

for(ax-5a) the common factor is a which will be factor out

Then after doing the process you will get

11(x-5)+a(x-5)

then factor out(x-5)which will give you

(11+a)(x-5)

Which ordered pair can be included in the table of values shown below for the equation p=25x-2?
pishuonlain [190]

Answer:

(0,-2)

Step-by-step explanation:

So since you are given the equation, p=25x-2, all you really need to do is plug in the ordered pairs and see which satisfies the equation.

This means makes both side have the same number value.

Let's try (x,p)=(-2,-2):

 p=25x-2 with (x,p)=(-2,-2)

-2=25(-2)-2

-2=-50-2

-2=-52

-2 and -52 do not represent the same number so (-2,-2) is not a point on the given line.

Let's try (x,p)=(-2,0):

p=25 x -2 with (x,p)=(-2,0)

0=25(-2)-2

0=-50-2

0=-52

0 and -52 do not represent the same number so (-2,0) is not a point on the given line.

Let's try (x,p)=(0,-2):

p=25 x  -2 with (x,p)=(0,-2)

-2=25(0)-2

-2=0   -2

-2=-2

-2 and -2 are the same number and so (0,-2) is a point on the line.

Let's try (x,p)=(0,0)

p=25 x  -2 with (x,p)=(0,0)

0 =25(0)-2

0 =  0   -2

0 =   -2

0 and -2 are not the same number so (0,0) is not a point on this line.
