(Note that the units cancel out so you end up getting the answer)

The final answer is 2 miles~

3. Write the following equation in slope intercept form: -2x + y = 9 A.) Y = -2x + 9 B.) Y = -2x – 9 C.) Y = 2x + 9 D.) Y = 2x –

Ira Lisetskai [31]

Hey! :)

So when we write something in slope intercept form, all we're doing is solving for y. So let's do that with this equation!

-2x + y = 9

add 2x to both sides

y = 2x + 9

So C is your answer.

Please let me know if you need anything further explained!

(3a^4b)(5ab^2)-(a^5b^2)(9b)

Sliva [168]

Answer:

The expanded value of the given expression is

$(3a^4b)(5ab^2)-(a^5b^2)(9b)=6a^5b^3$

Step-by-step explanation:

Given expression is

$(3a^4b)(5ab^2)-(a^5b^2)(9b)$

To find the value of the given expression:

$(3a^4b)(5ab^2)-(a^5b^2)(9b)=15a^5b^3-9a^5b^3$

(By multiplying the products and doing algebraci subtracion of the above expression)

Now taking the common terms in the above equation we get

$(3a^4b)(5ab^2)-(a^5b^2)(9b)=3a^5b^3(5-3)$

$=3a^5b^3(2)$

$=6a^5b^3$

Therefore the expanded value of the given expression is

$(3a^4b)(5ab^2)-(a^5b^2)(9b)=6a^5b^3$
