Answer:

D) 11x + 9

Step-by-step explanation:

3(2x + 5) - (-5x + 4) = (6x + 15) - (-5x + 4) = 6x + 15 + 5x - 4

add like terms:

(6x + 5x) + (15 - 4) = 11x + 9

If a dart board was thrown randomly at the dartboard shown below, what is the probability that it will land in the bull’s-eye? T
vampirchik [111]

Answer:

Correct option: C -> 2%

Step-by-step explanation:

To find this probability we just need to divide the area of the bull's-eye circle by the total area of the outer circle.

The area of a circle is given by the equation:

area = \pi * radius^2

The outer radius is 14 cm, so:

outer\ area = \pi * 14^2 = 196\pi\ cm^2

The inner radius is 2 cm, so:

inner\ area = \pi * 2^2 = 4\pi\ cm^2

So the probability is:

inner\ area / outer\ area = 4\pi / 196\pi = 0.02 = 2\%

Correct option: C

You have the right idea that things need to get multiplied.

What should be done is that the entire fraction needs to get multipled by the lowest common denominator of both denominators.

Let's look at the complex numerator. Its denominators are 5 and x + 6. Nothing is common with these, so both pieces are needed.

The complex denominator has x - 3 as its denominator. With nothing in common between it and the complex numerator, that piece is needed.

So we multiply the entire complex fraction by (5)(x + 6)(x -3).

Numerator: (\frac{1}{5} -\frac{5}{x + 6})(5)(x +6)(x-3) =\frac{1}{5}(5)(x +6)(x-3) -   \frac{5}{x + 6}(5)(x +6)(x-3)

= (x+6)(x-3) - (5)(5)(x-3)

= (x+6)(x-3) - 25(x-3)

= (x-3)(x + 6 - 25) <--- by group factoring the common x - 3

= (x -3)(x - 19)

Denominator:

\frac{25}{x - 3} * (5)(x + 6)(x - 3) = (25)(5)(x + 6) = 125(x + 6)


Now we put the pieces together.


Our fraction simplies to (x - 3) (x - 19) / 125 (x + 6)

12. Write the slope-intercept form of the equation of the line.
wlad13 [49]

Answer:

The answer is the first choice.

Step-by-step explanation:

We can eliminate choices 2 and 4 because the y-intercept is wrong. The line passes through the y-axis at 3, so you would add 3 after the slope. Now we have choices 1 and 3. Choice 1 is y=-4/5x+3 and choice 3 is y=4/5x+3. When we do rise over run, we can use the points (0,3) and (5,-1). We get -4/5. Therefore, the answer is choice 1.

I hope this helps and please mark me as brainliest!
