4x + y = 3y = -4x + 32x + y = -5y = -2x - 52x + 3y = 9y = -2/3x + 33x + 4y = -8y = -3/4x - 24x - 2y = 10y = 2x - 5-6x + 4y = -8y = 3/2x - 24x - y = 3y = 4x - 33x - y = -8y = 3x + 82x - 4y = 4y = 1/2x - 12x - 5y = 15y = 2/5x - 3What is a rational number?Any number that can be written as a fraction.What is an irrational number?A number that goes on forever and has no pattern.How do you write a repeating decimal as a fraction?Put a 9 under the repeating digit.

hope i'm right lol

Answer from: Quest

answer: solve 5\cdot 2^x=2405⋅2

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}

5⋅2

=240

=48
