Answer:
The expected speed is 80 km / h
Step-by-step explanation:
To solve this problem we must propose two equations that relate the data provided in the statement.
Initially it was expected to travel for 2.5 hours.
If we call V the speed at which the car would travel during that time and we also call x the distance traveled then we propose the following equation:
(i)
Then we know that if V increases 20 km/h then t decreases in 0.5 hours:
(ii) *We know that V = x/t
Then we substitute (i) in (ii)
The expected speed is 80 km/h
and the distance to be covered is 200 km
Answer:
This statement is "TRUE".
Step-by-step explanation:
Every elementary row operation is reversible. You can get the reverse answer by multiplying by a constant or by multiplying by its inverse. You can add one row to another row and subtract row 1 from row 2 to get it back.
The algebraic rule describes the 180° counter-clockwise rotation about the origin =======> Answer: Rule for 180 degrees Counter-Clockwise Rotation =======> ( X , Y ) =========> ( - X, - Y ) ====> Make X + Y Signs Opposite.
Rotations Counter-Clockwise:
Rotation of 90 degrees ========> Switch X + Y, Make Y Opposite.
Rotation of 270 degrees ======> ( X, Y ) ===> ( Y, - X ) ==> Switch X + Y, Make X Opposite.
Hope that helps!!!! : )
