The figure shows two parallel lines crossed by a line. We have completed the figure with another variable y. Please see the attached image.

Angles y and 4x+28 are linear, thus their sum is 180°:

y + 4x + 28 = 180

Angles y and 8x + 10 are corresponding, thus

y = 8x + 10

Substituting:

8x + 10 + 4x + 28 = 180

Simplifying:

12x + 38 = 180

Subtracting 38:

12x = 142

Dividing by 12

x = 11.83°

Answer:

Second option is the right choice.

Step-by-step explanation:

$Volume=2\pi rh+2\pi r^2\\\\V=2\left(3.14\right)\left(13\right)\left(14\right)+2\left(3.14\right)\left(13\right)^2\\\\\approx2205\:in^2$

What is the slope of the line that passes through the points (-3, 5) and (1, 7)?

Stells [14]

Answer: The slope of the line is $\frac{1}{2}$

Step-by-step explanation:

The slope of a line can be calculated with the following formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Then, given the points $(-3, 5)$ and $(1, 7)$ , you can identify that:

$y_2=5\\y_1=7\\\\x_2=-3\\x_1=1$

Knowing these values you can substitute them into the formula for calculate the slope:

$m=\frac{5-7}{-3-1}$

Finally, evaluating, you get that the slope of that line is:

$m=\frac{-2}{-4}\\\\m=\frac{1}{2}$
