First, we have to add them all together to get the total amount of markers.

2 + 1 + 3 + 2 + 2 = 10

Red: 3/10

Yellow: 2/9

3/10 x 2/9 = 6/90

Simplify: 6/90 = 1/15

C. 1/15 would be your answer.

Hope this helps! Have a great day!

Which of the following shows the extraneous solution(s) to the logarithmic equation? log4 (x) + log4(x - 3) = log4 (-7x + 21)
Salsk061 [2.6K]
First join the log4 on the left:

log4( x*(x-3) = log4(-7x+21)

Then x = -7, works: -7*(-10)=70 = -7*(-7)+21

x=-3, 18 = 42, does not work

x=3 0=0 works,

However, when one puts x = -7 in the *original* exression, log4(-7) or log4(-10) do not exist (you know why?). So x= -7 is extraneous.

Now x=3 gives log4(0) on the left and right, which does not exist.

So, C is the answer, both are extraneous. Seem to work but indeed don't work in the *original* equation

Which equation represents the graphed function ?
goldenfox [79]

Answer:

A

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (1, 1)

m = \frac{1-3}{1-0} = - 2

note the line crosses the y- axis at (0, 3) ⇒ c = 3

y = - 2x + 3  → A
