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 statements are true for the functions g(x)=x^2 and h(x)=-x^2? Check all that apply

galina1969 [7]

Answer:

if x=0 then they have same value

1 and 2 options are out

for x=-1

g(-1)=1

h(-1)=-1

3 is true

4th

FALSE

for all values except 0, g(x)>h(x)

correct ones are

g(x) > h(x) for x = -1.

For positive values of x, g(x) > h(x).

For negative values of x, g(x) > h(x).

Investment A 50 increases each year by 8% investment B 60 increases by 3 each year what year will investment A be bigger than be

UkoKoshka [18]

Answer:

After 10 years the investment A will be bigger than investment B.

Step-by-step explanation:

In Investment A, 50 increases each year by 8% and in investment B, 60 increases by 3 each year.

If after x years the investment A will be equal to investment B, then we can write the equation as

$50(1 + \frac{8 \times x}{100}) = 60 + 3x$

⇒ 50 + 4x = 60 + 3x

⇒ x = 10

Therefore, after 10 years the investment A will be bigger than investment B. (Answer)
