3 = q/11 i need it real quick

makkiz [27]

Answer:

$q=33$

Step-by-step explanation:

So we have:

$3=\frac{q}{11}$

Multiply both sides by 11:

$11(3)=(11)\frac{q}{11}$

The right side cancels:

$11(3)=q$

Multiply the left:

$33=q$

Thus, the value of q is 33.

One root of the quadratic equation x^2 − 2x + m = 0 is 9. If the other root is n, what is n−m?

mote1985 [20]

$9^2-2*9+m=0\\
\\
81-18+m=0\\
\\
m=-63$

$x^{2} -2x-63=0\\
\\
\Delta=(-2)^2-4.1.(-63)=4+252=256\\
\\
x=\frac{2 \pm 16}{2}\\
\\
x_1=\frac{18}{2}=9\\
\\
n=x_2=\frac{-14}{2}=-7\\
\\
n-n=-7-(-63)=-7+63=56$
