Answer:

Sound can travel 12 miles per minute.

Step-by-step explanation:

Speed equation is distance divided by time.

So we have 1 mile per 1/12 of a minute.

Let’s write the equation.

Speed of sound = 1 / 1/12

Multiply by the reciprocal.

1 * 12 = 12.

A line passes through the points (7, 10) and (7, 20). Which statement is true about the line? It has a slope of zero because in

geniusboy [140]

Slope formula: $\frac{y2-y1}{x2-x1}$
Apply.
$\frac{20-10}{7-7} = \frac{10}{0} =$ undefined (No slope)

Thus, that answer is: Choice D.

If you're wondering why C isn't this answer, it's because it doesn't matter if 0 is the numerator of a fraction. If it was, then the slope would be 0 regardless. However, if 0 takes place in the denominator, the slope will be undefined; there will be no slope.

Step-by-step explanation:

Given points are:

$(-1,\:3)=(x_1,\: y_1) \:\&\:(1, \:7)=(x_2,\:y_2)$

Equation of line in two point form is given as:

$\frac{y-y_1 }{y_1 - y_2} = \frac{x-x_1 }{x_1 - x_2} \\ \\ \therefore \: \frac{y - 3}{3 - 7} = \frac{x - ( - 1)}{ - 1 - 1} \\ \\ \therefore \: \frac{y - 3}{ - 4} = \frac{x + 1}{ - 2} \\ \\ \therefore \: \frac{y - 3}{ 2} = \frac{x + 1}{ 1} \\ \\ \huge \purple{ \boxed{\therefore \:y - 3 = 2(x + 1)}} \\ this \: is \: the \: equation \: of \: line \: in \: \\ point - slope \: form.\\simplifying \: it \: further \: we \: find: \\ y - 3 = 2x + 2 \\ \\ \therefore \:y = 2x + 2 + 3 \\ \\ \huge \red{ \boxed{\therefore \:y = 2x + 5}} \\ this \: is \: the \: equation \: of \: line \: in \: \\ slope - intercept \: form.$
