The top graph

Step-by-step explanation:

The first difference is the top graph says that there are 3 pieces of data between 1-5 and the bottom says 4 pieces. There are actually 3 pieces between 1-5 so the top graph is correct.

Find r if 3(r - 7) = 4(2 - 2r) + 4
Arturiano [62]

Answer:

r=3

Step-by-step explanation:

3(r - 7) = 4(2 - 2r) + 4

Distribute

3r -21 = 8 -8r +4

Combine like terms

3r -21 = 12 -8r

Add 8r to each side

3r +8r-21 = 12 -8r+8r

11r -21 = 12

Add 21 to each side

11r -21+21 =12+21

11r = 33

Divide each side by 11

11r/11 = 33/11

r = 3

Write as a product of 2 binomials and a monomial (factor out as much as possible from each binomial). (14x+21y)(6ab–3a)
mihalych1998 [28]

Answer: The answer is 21a(2x+3y)(2b-1).


Step-by-step explanation: Given expression is as follows

E=(14x+21y)(6ab-3a).

We are to write the above expression "E" as a product of two binomials and a monomial.

A monomial is an expression with a single term and a binomial is an expression with two terms.

So, let us start as follows -

E\\\\=(14x+21y)(6ab-3a)\\\\=7(2x+3y)3a(2b-1)\\\\=21a(2x+3y)(2b-1).

Here,

21a~\textup{is a monomial and}~(2x+3y),~(2b-1)~\textup{are binomials}.

Thus, the required factorisation is

E=21a(2x+3y)(2b-1).

Hey! I need help with these two (not just one, both) as soon as possible!
torisob [31]

Answer:

1. 1/2(x - 3)³

2. 3x/y²

Step-by-step explanation:

1. to simplify, we could just FOIL the equations out, but since this is a division, we can cancel out any common factors in the numerator and the denominator to make it easier

2(x - 3)³

----------

4(x- 3)^6

what do these two have in common? both have a (x - 3)³ to start off, so we can cancel out the (x - 3)³ in the numerator, and take the diference in the denominator which gives us (x - 3)³

2(x - 3)³ / (x - 3)³ = 2

4(x - 3)^6 / (x - 3)³ = 4(x - 3)³

so now we have:

2

-----

4(x - 3)³

we can simplify 2/4 and get 1/2 so now we have the following:

 1

--------

2(x - 3)³

there is nothing else to simplify, so this is the final answer

2. to solve 8x/y² - 5x/y², we see they both have <em>like denominators</em>, this means that we can just combine the terms over one denominator and we get the following:

8x - 5x

----------

   y²

we can subtract 5x from 8x because both have an x in them and are therefore able to be subtracted

8x - 5x = 3

so the final answer is 3x/y²
