In a valcano, erupting lava flows continuously through a tube system about 19 kilometers to the sea. assume a lava flow speed 0.

Sunny_sXe [5.5K]

Lava flows continuously about 19 kilometers to sea if speed of lava is 0.5 kilometer per hour then it will take 38 hours to reach the sea.

As given,

Distance covered = 19kilometers

Speed of lava = 0.5 kilometer per hour

0.5 kilometers=1 hour

⇒ 1kilometers = (1/0.5)hour

⇒ 19 kilometers = (19 / 0.5) hour

⇒ 19 kilometers = 38 hours

Therefore, lava flows continuously about 19 kilometers to the sea if speed of the lava is 0.5 kilometer per hour then it will take 38 hours to reach the sea.

Write an equation for the line (4,7) and ( 1,1)2. Write an equation for the graph

Nastasia [14]

ANSWER:

$y=2x-1$

STEP-BY-STEP EXPLANATION:

We have that the equation in its slope-intercept form is the following:

$\begin{gathered} y=mx+b \\ m\text{ is the slope and b is the y-intercept } \end{gathered}$

The slope can be calculated as follows:

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

We use the points (4,7) and (1,1) to calculate the slope:

$m=\frac{1-7}{1-4}=\frac{-6}{-3}=2$

Now, we calculate the value of b, using the point (1,1) and the slope, like this:

$\begin{gathered} 1=1\cdot2+b \\ b=-2+1 \\ b=-1 \end{gathered}$

Therefore, the equation would be:

$y=2x-1$
