Nina knows that the average of the x-intercepts represents the line of symmetry for a quadratic function through the x-axis
Which equation represents the average of the x-intercepts for x) = 4x2-24x + 207

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

investment b is an ordinary annuity with $3,909.64 in the account after one year.

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

=240

=48
