Answer:

x = 8

Step-by-step explanation:

This is an equilateral triangle, so we know that the angles are all equal too.

That means each angle is 60 degrees (b/c 60 * 3 = 180)

7x + 4 = 60

7x = 56

x = 8

The graph of an absolute value function opens down and has a vertex of (0, -3). The domain of the function is . The range of the

Firdavs [7]

Answer:

Domain: All real numbers

Range: $y\leq -3$

Step-by-step explanation:

The domain is the set of all x values. The quadratic equation continue to operate over all x-values in both directions. The domain is all real numbers.

The range is the set of all y-values. Here the quadratic begins at -3 and continues in a downward direction forever. Then range is $y\leq -3$

What is the value of log 27^9?

KengaRu [80]

Answer: The answer is $\dfrac{2}{3}.$

Step-by-step explanation: We are given to find the value of $\log_{27}9.$

Here, we will be using the following properties of logarithm.

$(i)~\log a^b=b\log a,\\\\(ii)~\log_ba=\dfrac{\log a}{\log b}.$

So, we will be solving the given problem using these two as follows.

$\log_{27}9=\dfrac{\log9}{\log27}=\dfrac{\log 3^2}{\log 3^3}=\dfrac{2\log 3}{3\log 3}=\dfrac{2}{3}.$

Thus, the required value is $\dfrac{2}{3}.$

For every $50.00. Michael earns, he saves $5. for the future. How much money will he have saved when he earns a total of $500.

xeze [42]

The answer is D

This is because if for every $50 he saves $5, and he has saved a total of $500, you can set up a proportion to find out how much money he has saved at that point.

The proportion is as follows:

50/5 == 500/x

x is equivalent to the amount of money he has saved

You can cross multiply to get the following equation:

50x == 2500

To isolate x, you must divide both sides by 50, giving you an answer of:

x = 50

This is the same as option D
