Find all solutions to the following equation. If there are any extraneous solutions, identify them and explain why they are extr
vagabundo [1.1K]

Answer:

b = 3, which is an extraneous solution because if we replace b = 3 in the equation, we must be 5/0 and 30/0, and there is division by 0.

Step-by-step explanation:

\frac{7}{b+3} + \frac{5}{b-3} = \frac{10b}{b^2-9}

The minus common multiply must be (b-3)*(b+3) = b² - 9

\frac{7*(b-3)}{b^2-9} + \frac{5*(b+3)}{b^2 -9}  = \frac{10b}{b^2-9}

7b - 21 + 5b + 15 = 10b

2b = 6

b = 3

Which is an extraneous solution because if we replace b = 3 in the equation, we must be 5/0 and 30/0, and there is division by 0. So this solution is invalid.

Which logarithmic equation is equivalent to the exponential equation below?
Nataly_w [17]
With any equation you are allowed to take the logarithm of both sides so
5^c=125 now take the logarithm base 5 to both sides giving.
log5(5^c)=log5(125), using the rule log(a^b)=a*log(b) you get
c log5(5)=log5(125), since log5(5)=1
c=log5(125)

g A restaurant offers 7 entrees and 11 desserts. In how many ways can a person order a two-course meal?
Kitty [74]

Answer:

2-course\ meal = 77\ ways

Step-by-step explanation:

Given

Entrees = 7

Desserts = 11

Required

Determine the number of ways to get a two-course meal

This is solved as follows:

<em>The entrees can be ordered in 7 ways</em>

<em>The desserts can be ordered in 11 ways;</em>

2-course\ meal = Entrees * Desserts

Hence:

2-course\ meal = 7 * 11

2-course\ meal = 77\ ways
