Solve for x : log(3x) + log(x + 4) = log(15).<br><br>Please explain it to me.​
zlopas [31]

Answer:

x = 1

Explanation:

\sf \rightarrow log(3x) + log(x + 4) = log(15)

Rule: log(a) + log(b) = log(ab)

\sf \rightarrow log(3x(x + 4)) =  log(15)

cancel out log on both sides

\sf \rightarrow 3x(x + 4) = 15

relocate constant variable

\sf \rightarrow 3x^2 + 12x -15 = 0

take 3 as a common factor

\sf \rightarrow 3(x^2 + 4x -5) = 0

divide both sides by 3

\sf \rightarrow x^2 + 4x -5 = 0

middle term split

\sf \rightarrow x^2 + 5x -x-5 = 0

factor common terms

\sf \rightarrow x(x  + 5) -1(x+5)= 0

collect into groups

\sf \rightarrow (x-1)(x+5)= 0

set to zero

\sf \rightarrow x-1 = 0 , \ x+5= 0

relocate variables

\sf \rightarrow x = 1,  \ x = -5

There must be a positive solution for log, so the solution is only x = 1

What is the equation of the funcion that is graphed as line b?
dolphi86 [110]

Answer:

The equation for b would be y = 1/2x + 1

Step-by-step explanation:

In order to find this, start by finding two points on the line. We'll use (0,1) and (2, 2). From there we start by finding the slope.

m(slope) = (y2 - y1)/(x2 - x1)

m = (2 - 1)/(2 - 0)

m = 1/2

Now using that, we can plug it, along with a point into point-slope form to get the answer.

y - y1 = m(x - x1)

y - 1 = 1/2(x - 0)

y - 1 = 1/2x

y = 1/2x + 1

grandymaker [24]
2 1/2 pounds of apple makes serve 6
(2 1/2 x 24)/6 = 10 pounds of apple will make serve 24.

Therefore, she will use 10 pounds of apples.
