I have this problem for hw and it’s due tomorrow. can someone please help me? (it’s y-4 not 4-4)

Vesnalui [34]

Answer:

All real numbers

Step-by-step explanation:

$-2(y - 4) = 20 - 2y - 12$

Start by distributing -2 inside the parentheses.

$-2y + 8 = 20 - 2y - 12$

Combine like terms on the right side of the equation.

$-2y + 8 = 8 - 2y$

Subtract 8 from both sides of the equation.

$-2y =- 2y$

Divide both sides by -2 to isolate y.

$0=0$

This is a true statement, so there are infinite solutions.

$y=a(b)^x$ where a is the initial value and b is the growth rate. Our initial value is 490 and our growth rate is .2 so the equation is

$y=490(.2)^x$
