1 answer:

8 0

Alright so 5x-4+2x=3 so we are solving for x so 5x+3x=7x so you are left with 7x-4=3 then you add 4 to 3 on the other side that leaves you with 7x=7 so then divide 7 from 7 then you will get x=1

A car wash attendant counted the number of cars washed and the total amount of money earned. The company charged the same price

Bogdan [553]

The answer is m(n)= 11n
If you take the different of the money from 21 cars and 25 cars, you get 44 and since 21 and 25 is only a difference of 4, you’ll divide the 44 earned by the 4 cars washed to get $11 per car and then just make sure to use the correct variables

If f(x) = 2x2 - x - 6 and g(x) = x2 - 4, find f(x) ÷ g(x).

Phantasy [73]

$f(x)=2x^2-x-6,\ g(x)=x^2-4\\\\f(x)\div g(x)=\dfrac{f(x)}{g(x)}=\dfrac{2x^2-x-6}{x^2-4}=\dfrac{2x^2-4x+3x-6}{x^2-2^2}\\\\=\dfrac{2x(x-2)+3(x-2)}{(x-2)(x+2)}=\dfrac{(x-2)(2x+3)}{(x-2)(x+2)}=\dfrac{2x+3}{x+2}\ for\ x\neq0\\\\Answer:\ f(x)\div g(x)=\dfrac{2x+3}{x+2}$
