You drive 15 miles in one fourth of an hour. What is your average speed?
Mazyrski [523]
Hello ! I'm happy to help
the answer all revolves around this simple formula:
speed= distance/time
since you were driving for 1/4 of an hour that's 15 minutes
and we already know that you traveled 15 miles
so the speed would equal 15 miles every 15 minutes
if you want to find the total distance travelled is 15x15 =225

Find the equation of the line with a slope of 4 and passing through (0,3)
Simora [160]

4x -  y + 3 =0 is the equation of the line

Step-by-step explanation:

Given:

The slope of the line  =  5

The points through with the line passes = (0,3)

To Find:

The equation of the line  =?

Solution:

The equation  y = mx + b

where m is the slope and (0,b) is the y-intercept.

The slope is given which is m = 4 and a point (0,3)

Then you can use slope-point equation

y - y_o = m(x - x_o)

where (x_o,y_o) is the given point

y - (3) = 4(x - 0)

y - 3 = 4(x)

y = 4x - 22

y - 3 = 4x

4x - y + 3 = 0
