Answer:

Step-by-step explanation:

The parallel lines must have the same slope.

The slope of the given line is 3.

So the parallel line has slope 3 and passes through (1,1)

The general equation of the line is y = m*X + b where m is the slope and b is the intercept.

Solving for B, the intercept is B = y - m*x.

Because (1,1) is on this line X=1, Y=1, and M=3

Plugging them in and substituting:

B = 1 - 3*1 = 1 - 3 = -2.

So the y-intercept of the parallel line is -2.

The equation of the parallel line is y = 3x + -2 = 3x - 2

The original line crosses the y-axis at y=3, while the parallel line

cross the y-axis at y=-2, which is 4 squares down on the

graph paper. With the slope of 3, M=3 = 3/1 = rise/run --> up three and on to the right.

You can now draw the graphs.

Answer: See below; x=1/6

Step-by-step explanation:

This problem may seem intimidating, but all you need to know are your exponent rules. Let's first work inside the parenthesis. Since the bases are the same, we can directly subtract the exponents.

$\frac{3}{4} -\frac{3}{8}$ [common denominator]

$\frac{6}{8} -\frac{3}{8}$ [subtract]

$\frac{3}{8}$

Now, our new answer is $(3^\frac{3}{8} )^\frac{4}{9}$ .

Unfortunately, the answer is asking for an exponent with a single base. One of the properties is when the exponents are separated by parenthesis, you multiply them together.

$\frac{3}{8} *\frac{4}{9}$ [cross cancel to simplify]

$\frac{1}{2} *\frac{1}{3}$ [multiply]

$\frac{1}{6}$

Our final answer is $3^\frac{1}{6}$ .

The value is x is $\frac{1}{6}$ since $3^\frac{1}{6}$ is equal to $3^x$ , we know that $x=\frac{1}{6}$ .

The blades of a windmill turn on an axis that is 30 feet from the ground. The blades are 10 feet long and complete 2 rotations e

Tasya [4]

The sine model is y=10 sin(1/30 t) + 30. The 30 represents default distance from the ground, and the ten is required to represent the length of the blades. Every 30 seconds, one rotation completes, so t must be multiplied by 1/30.

What is a rational inequality?

Advocard [28]

A rational inequality is "an inequality which contains a rational expression." When trying to solve rational inequality's you need to first find the zeros, two find the undefined points then you divide the two in order to get your answer.

Hope this helps!
