On a coordinate grid, point A is at (−3.0, −5.4) and point B is at (−3.0, 5.4). Point B is a reflection of point A across the ___–axis. Input either a lowercase x or y.

Answers

Answer 1

Answer: Given:
Point A (-3.0,-5.4)
Point B (-3.0,5.4)

reflection across y-axis ⇒ (a,b) reflected (-a,b)
reflection across x-axis ⇒ (a,b) reflected (a,-b)
reflection across the origin ⇒ (a,b) reflected (-a,-b)
reflection on y = x ⇒ (a,b) reflected (b,a)

Point B is a reflection of Point A across the x-axis.

Two Amtrak trains traveling on parallel tracks leave Tucson at the same time. In 6 hours the faster train is 382 miles from Tucson and the trains are 112 miles apart. Find how fast each train is traveling.

Answers

Answer: the faster train is travelling at 63.7 mph

The slower train is travelling as 45 mph

Step-by-step explanation:

Distance = speed × time

Speed = distance/time

The two trains leave Tucson at the same time. In 6 hours, the faster train is 382 miles from Tucson. This means that the speed at which the faster train is travelling is

382/6 = 63.7mph

In 6 hours, both trains are 112 miles apart. This means that the distance covered by the slower train in 6 hours is

382 - 112 = 270 miles

Therefore, the speed at which the slower train is travelling is

270/6 = 45 mph

AC=A, C, equals
Round your answer to the nearest hundredth.

Answers

Answer:

We have the equation A*C = A

Now, as both sides of the equality are the same thing, we can do the same operation to both sides and the equality will remain true.

We can divide both sides by A and get:

(A*C)/A = A/A

C = 1

So here we finded the value of A.

If A and C are matrices, then C is the identity matrix.

The given statement is mathematically impossible, as there is no number that is equal to both itself and its opposite. Therefore, the answer is undefined.

In other words, there is no number that can be substituted for both A and C in the equation AC = A, C to make it a true statement.

Here is a more detailed explanation:

If A is equal to zero, then C would also have to be equal to zero. But this would mean that AC = 0, which is not equal to A, C.

If A is any other number, then C would have to be equal to the negative of A. But this would mean that AC = -A, which is not equal to A, C.

Therefore, there is no solution to the equation AC = A, C.
