Triangle ABC is labeled with points A(5, 2), B(1, 2) and C(3, 6) on a coordinate plane. Find the coordinates of A' B' C' after a
Ilia_Sergeevich [38]

Answer:

After reflection over the x-axis, we have the coordinates as follows;

A’ (5,-2)

B’ ( 1,-2)

C’ (3,-6)

Step-by-step explanation:

Here, we want to find the coordinates A’ B’ and C’ after a reflection over the x-axis

By reflecting over the x-axis, the y-coordinate is bound to change in sign

So if we have a Point (x,y) and we reflect over the x-axis, the image of the point after reflection would turn to (x,-y)

We simply go on to negate the value of the y-coordinate

Mathematically if we apply these to the given points, what we get are the following;

A’ (5,-2)

B’ ( 1,-2)

C’ (3,-6)

How much longer, to the nearest minute, would it take to travel 290 miles at 60mph versus 70 mph.
velikii [3]
So using the equation distance = velocity * time
we get distance/velocity = time
60 MPH: 290/60 = 4.83333 Hours
60 MPH: 290/70 = 4.1429 Hours

Difference between them:
4.8333 - 4.1429 = 0.69 Hours, then multiply that by 60 and you get
41 Minutes.

Hope this helped!
*psst it would help if you gave me brainliest answer, I'm close to ranking up :) Thanks!
