The average rate of change of f(x)=3x+9 is 9. true or false?
MA_775_DIABLO [31]
The rate of change is the slope.
f(x) is the same as y...
f(x) = 3x + 9.....y = 3x + 9....and in y = mx + b form, the rate of change(slope) can be found in the m position.

y = mx + b
y = 3x + 9....so the slope or rate of change is 3...not 9...so answer is false

Which expressions are equivalent? Select two answers.
professor190 [17]

Answer:

<h2>A, C</h2>

Step-by-step explanation:

The distributive property:

<em>a(b + c) = ab + ac </em>or<em> a(b - c) = ab - ac</em>

<em></em>

A.\\\\\dfrac{1}{5}(x-50)=\dfrac{1}{5}x-\left(\dfrac{1}{5}\right)(50)=\dfrac{1}{5}x-\dfrac{50}{5}=\dfrac{1}{5}x-10\\\\B.\\\\-\dfrac{1}{3}(3x+18)=\left(-\dfrac{1}{3}\right)(3x)+\left(-\dfrac{1}{3}\right)(18)=-\dfrac{3}{3}x-\dfrac{18}{3}=-x-6\\\\-x-6\neq\dfrac{1}{3}x-6

C.\\\\\dfrac{1}{2}(x+16)=\dfrac{1}{2}x+\left(\dfrac{1}{2}\right)(16)=\dfrac{1}{2}x+\dfrac{16}{2}=\dfrac{1}{2}x+8\\\\D.\\\\\dfrac{1}{8}(8x+8)=\left(\dfrac{1}{8}\right)(8x)+\left(\dfrac{1}{8}\right)(8)=\dfrac{8}{8}x+\dfrac{8}{8}=x+1\\\\x+1\neq\dfrac{1}{8}x+1\\\\E.\\\\-\dfrac{1}{4}(x+2)=-\dfrac{1}{4}x+\left(\dfrac{1}{4}\right)(2)=-\dfrac{1}{4}x+\dfrac{2\!\!\!\!\diagup^1}{4\!\!\!\!\!\diagup_2}=-\dfrac{1}{4}x+\dfrac{1}{2}\\\\-\dfrac{1}{4}x+\dfrac{1}{2}\neq-\dfrac{1}{4}x+2

wo urns contain white balls and yellow balls. The first urn contains 3 white balls and 6 yellow balls and the second urn contain
vlada-n [284]

Answer:

Answer is

\frac{7}{30}

Step-by-step explanation:

Given that there are two urns.  First urn contains 3 white balls and 6 yellow balls and the second urn contains 7 white balls and 3 yellow balls.

A ball is drawn from each urn.

Probability for ball from urn I is white = no of white balls/total balls in I urn

= \frac{3}{9} =\frac{1}{3}

Probability for ball from urn II is white = no of white balls/total balls in I urn

=\frac{7}{10}

Since drawing one ball from each urn is independent of the other we find

Prob that both balls are white=

Prob that ball from I urn is white *Prob that ball from II urn is white

== \frac{7}{10} *\frac{1}{3}\\=\frac{7}{30}
