Anthony jogs 11 1/2 miles in 23 mins. If Anthony continues to jog at a steady pace, how many miles will he jog each minute?

frozen [14]

For this case we can raise a rule of three based on Anthony trotting $11 \frac {1} {2}$ miles in 23 minutes.

$11 \frac {1} {2} = \frac {2 * 11 + 1} {2} = \frac {23} {2}$

$\frac {23} {2}$ miles -----------> 23 minutes

x ----------------------------------------> 1minute

$x = \frac {\frac {23} {2} * 1} {23}\\x = \frac {\frac {23} {2}} {23}\\x = \frac {23} {2 * 23}\\x = \frac {1} {2}$

ANswer:

0.5 miles per minute

A line passes through the point (-8, 6) and has a slope of 3/2

Vladimir79 [104]

Answer:

y-6=3/2(x+8)

Step-by-step explanation:

so the point slope form is y-y₁=m(x-x₁)

so enter the points (-8, 6)

y-6= 3/2(x-(-8))

y-6=3/2(x+8)
