The function d(x)=1375-110x represents the distance (in miles) a high speed train is from its destination after x hours.
how long does the train travel before reaching its destination?

12.5 hours

Step-by-step explanation:

The function d(x) = 1375 -110x represents the distance in miles a high-speed train is from its destination after x hours of travel.

So, when the train reaches its destination then d(x) will become zero miles.

Therefore, 0 = 1375 - 110x

⇒ x = 12.5 hours.

So, the train will travel 12.5 hours to reach its destination. ( Answer )

false

step-by-step explanation:

whenever we assume a point on a plane then according to geometry it will definitely have 2 dimensions and if it assumed in space then it will have 3 dimensions.

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
