Bogdan [553]

Answer:

D) 8.667 mph

Step-by-step explanation:

Given: Distance= 6.5 miles

           Times= 45 minutes

First, convert the time into hours as we need to find speed in the unit of mph.

We know, 1 hour= 60 minutes

∴ Time= \frac{45}{60} = 0.75\ h

Now, find the speed of John´s bike

Speed= \frac{distance}{time}

⇒ Speed= \frac{6.5}{0.75} = 8.667\ mph

∴ Speed of John´s bike is 8.667 mph

What is the slope of a line perpendicular to the line whose equation is
Marina86 [1]

Answer:

The slope of a line perpendicular to the line whose equation is 4x - 5y = 10 is -5/4.

Step-by-step explanation:

provided the equation;

4x- 5y=10.(let it be equation of line1 )

and the other line be line2

from perpendicularty principle

M1×M2= -1

BUT for M1(slope of line L1)

y= mx+c

where "c" is constant value.

"m" is slope.

therefore

5y= 4x - 10

(dividing by five throughout)

y=(4x/5) - 2

y= (4/5)x - 2

therefore M1= (4/5)

Returning back to our principle

M1×M2= -1

(4/5)M2=-1

<u>M2= -5/4</u>
