8u/u^2-18u+81 subtract 72/u^2-18u+81
Karo-lina-s [1.5K]
Your question is:
\frac{8u}{u^2-18u+81} -\frac{72}{u^2-18u+81}
Then, the above formula equate:

\frac{8u-72}{u^2-18u+81}
Factor out 8 from the numerator we get:
\frac{u-9}{u^2-18u+81}
Factorization of the denominator:
\frac{u-9}{(u-9)^2}
Simplifying the numerator and the denominator by (u-9) we get:
\frac{1}{(u-9)}

Select the graphs that have an equation with a < 0.
Eddi Din [679]

Answer:

Second graph only.

Step-by-step explanation:

The standard equation of a parabola is ax^2+bx+c where a,b and c are coefficients.

If the coefficient of (a) is positive then the parabola is concave upwards (as in picture 1)

If the coefficient of (a) is negative then the parabola is concave downwards as in picture 2.
