Answer:

1 1/2 miles

Step-by-step explanation:

if running 1 lap around a track is 1/2 miles then all we have to do is add it up

so we know that 1/2 miles is one lap

so if he runs two laps we would have run 1 mile

now that we know that he would have ran 1 mile in 2 laps then all we have to do it just add 1 more 1/2 mile in which would give u the answer of 1 1/2 miles or 1.5 miles

Which equation represents the line that is perpendicular to y = 5 and passes through (-4,-3)?

kenny6666 [7]

Answer:

The required equation is: y=-3

Option D is correct.

Step-by-step explanation:

We need to write equation of line that is perpendicular to y = 5 and passes through (-4,-3).

The equation of line in slope-intercept form is expressed as: $y=mx+b$

where m is slope and b is y-intercept.

Finding Slope:

Comparing with the given equation y=5, the slope m =0

The slope of required line will be opposite reciprocal of 0 as both lines are perpendicular. so it will be m=0

Finding y-intercept

The y-intercept can be found using slope m=0 and point (-4,-3)

$y=mx+b\\-3=0(-4)+b\\b=-3$

So, y-intercept b is b=-3

The equation of required line having slope m=0 and y-intercept b=-3 is

$y=mx+b\\y=0(x)-3\\y=-3$

So, required equation is: y=-3

Option D is correct.

Every function associates input values with output values. The domain of a function is the set of all the inputs the function accepts.

You will basically always find your function graphed with the inputs on the horizontal axis and the outputs on the vertical axis. This means that every point on the graph has coordinates $(x,f(x))$ , and the domain is the set of all the x values.
