We have this equation:

$\log(x) + \log(x + 99) = 2$

First, combine both logarithms using the multiplication property and simplify the expression.

$\log[x(x + 99)] = 2$

$\log[ {x}^{2} + 99x ] = 2$

Now, use the definition of logarithm to transform the equation.

${10}^{2} = {x}^{2} + 99x$

${x}^{2} + 99x - 100 = 0$

Finally, use the quadratic formula to solve the equation.

$x = \frac{ -99 ± \sqrt{ {99}^{2} - 4 \times 1 \times ( - 100)} }{2 \times 1}$

With this, we can say that the solution set is:

x = 1
x = -100

We cannot choose x = -100 as a solution because we cannot have a negative logarithm. The only solution is x = 1.

For which value of x is the equation 2(1 + x) = x + 3 true? A) 1 B) 2 C) 3 D) 4

amm1812

Answer:

A) 1

Step-by-step explanation:

To solve, just plug in the numbers to the equation for x until both sides are equal to each other.

Plug in 1:

2(1 + x) = x + 3

Let x = 1:

2(1 + 1) = 1 + 3

Solve. Remember to follow PEMDAS. First, add parenthesis, then multiply. On the other side, add:

2(1 + 1) = 1 + 3

2(2) = 4

4 = 4 (True)

A) 1 is your answer.

114 = 3x + 18

Mama L [17]

Answer: x = 32 y = 20

Step-by-step explanation:

114 = 3x + 18 114 = 3(y + 18)

-18 - 18 /3 /3

= =

96 = 3x 38 = y + 18

/3 /3 -18 -18

= =

32 = x 20 = y
