Write the equation 0.3x2 + 5x - 7 =0 in general form and then choose the value of "b."

For this case we have that by definition, an equation of the second degree is given by:

We have the following equation:

Then, according to the definition above, we have to:

Thus, b equals 5.

Option C

step-by-step explanation:

answer: solve 5\cdot 2^x=2405⋅2  

x

=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  

x
