17.2046505341 is the answer
By using change base formula which is :
log x to the base b = (log x)/(log b) to a new base
∴ log₄(x+3) = log (x+3) / log 4
and
log₂(2+x) = log (2+x) / log 2
∴ the correct answer is number one
See the attached figure.
Equation of a line is given by y = mx + c; where m is the slope.
5x + 2y = 9
2y = 9 - 5x
y = -5/2 x + 9/2
Therefore, slope = -5/2
