Log3x - log3(x − 8) = 2?????

Answers

Answer 1
Answer:

Answer:To solve the equation log3x - log3(x - 8) = 2, we can use the properties of logarithms to simplify and solve for x.

First, let's apply the quotient rule of logarithms. The quotient rule states that log(base a)(b) - log(base a)(c) = log(base a)(b/c).

Using this rule, we can rewrite the equation as log3(x / (x - 8)) = 2.

Next, let's rewrite 2 as a logarithm. The logarithmic form of 2 is log(base a)(b) = c, where a^c = b. In this case, a^c = 3^2 = 9. Therefore, we can rewrite the equation as log3(x / (x - 8)) = log3(9).

Now that the bases are the same, we can set the arguments of the logarithms equal to each other. Therefore, x / (x - 8) = 9.

To solve for x, we can multiply both sides of the equation by (x - 8) to eliminate the fraction. This gives us x = 9(x - 8).

Expanding the right side of the equation, we get x = 9x - 72.

Next, we can subtract 9x from both sides of the equation to isolate x. This gives us -8x = -72.

Dividing both sides of the equation by -8, we find that x = 9.

Therefore, the solution to the equation log3x - log3(x - 8) = 2 is x = 9.

Suppose that the cost of a paving stone is $2.50 plus $.18 for every 4 in.³ of concrete how much would each paving stone cost ?

Answers

We need to know the dimension of the paving stone.

For example, the paving stone is shaped like a rectangular prism with the following dimension.

Length = 10 inches
Width = 3 inches
Height = 2 inches

Volume of a rectangular prism = Length * Width * Height
V = 10 in * 3 in * 2 in
V = 60 in³

60 in³ / 4 in³ = 15

cost of paving stone = 2.50 + .18(15) = 2.50 + 2.7 = 5.20 per paving stone.

Write the equation of the line in slope-intercept form that has: slope: -1 point: (2, -3) *

Answers

Answer:

y = -x - 1

Step-by-step explanation:

Slope - Intercept form is y = mx + b

m = slope

b = y-intercept

We already have the slope of -1.  Substitute it into the equation.

y = -x + b

To find b, substitute the given point (2, -3) into the equation.  

-3 = -2 + b

b = -1

Substitute the value of b into the equation and you are left with:

y = -x - 1

Answer:

y = -1x - 3

Step-by-step explanation:

y = mx + b

m = slope = -1

b = y-intercept = -3

Plug in

y = -1x - 3
