Answer:

x = 4

Step-by-step explanation:

9(x - 2) = 18

9 * x = 9x

9 * -2 = -18

9x - 18 = 18

+18 +18

9x - 18 + 18 = 9x

18 + 18 = 36

9x = 36

---- -----

9 9

9x/9 = x

36/9 = 4

x = 4

Answer: x=4

Explanation:

Parenthases first. 4-2 = 2

Now multiply. 9 * 2 = 18

18=18

This equation is correct.

A bag contains 6 red tiles, 8 blue tiles, and 6 green tiles. A tile is drawn, the color recorded, and then the tile placed back

tester [92]

Answer:

9 red tiles

Step-by-step explanation:

Total number of tiles: $6+8+6=20$

Total number of red tiles: $6$

Probability of getting red in one draw: $\frac{6}{20}=0.3$

This means that you would expect to get red $0.3$ or 30% of the times.

Hence, when you draw tiles 30 times from the bag, you would expect red to be picked 30% of 30 times. This is:

$0.3*30=9$

So, you would expect to draw a red tile from the bag 9 times.

Find the roots of the following function: y = x2 − 7x − 30

DIA [1.3K]

Answer:

x = 3, −10

Step-by-step explanation:

The roots (zeros) are the x values where the graph intersects the x-axis. To find the roots (zeros), replace y with 0 and solve for x.

Properties of Logarithms

We'll recall below the basic properties of logarithms:

$log_b(1) = 0$

Logarithm of the base:

$log_b(b) = 1$

Product rule:

$log_b(xy) = log_b(x) + log_b(y)$

Division rule:

$\displaystyle log_b(\frac{x}{y}) = log_b(x) - log_b(y)$

Power rule:

$log_b(x^n) = n\cdot log_b(x)$

Change of base:

$\displaystyle log_b(x) = \frac{ log_a(x)}{log_a(b)}$

Simplifying logarithms often requires the application of one or more of the above properties.

Simplify

$\displaystyle log_\frac{1}{2}(64)$

Factoring $64=2^6$ .

$\displaystyle log_\frac{1}{2}(64)=\displaystyle log_\frac{1}{2}(2^6)$

Applying the power rule:

$\displaystyle log_\frac{1}{2}(64)=6\cdot log_\frac{1}{2}(2)$

Since

$\displaystyle 2=(1/2)^{-1}$

$\displaystyle log_\frac{1}{2}(64)=6\cdot log_\frac{1}{2}((1/2)^{-1})$

Applying the power rule:

$\displaystyle log_\frac{1}{2}(64)=-6\cdot log_\frac{1}{2}(\frac{1}{2})$

Applying the logarithm of the base:

$\mathbf{\displaystyle log_\frac{1}{2}(64)=-6}$
