x + 3y = 7 x - 3y = 1 Solve the system of equations. A) x = 4, y = 1 B) x = 1, y = 4 C) x = - 2 3 , y = 3 Eliminate D) x = 3, y

Answer:

x=4, y=1

Step-by-step explanation:

x + 3y = 7

x - 3y = 1

Add the equations together to eliminate y

x + 3y = 7

x - 3y = 1

---------------------

2x = 8

Divide by 2

2x/2 = 8/2

x = 4

Subtract the two equations to eliminate x

x + 3y = 7

-x + 3y = -1

----------------------

6y = 6

Divide by 6

6y/6 = 6/6

y =1

The Pythagorean Theorem is a^2 + b^2 = c^2
It’s usually used on triangles when two sides are given but one isn’t. C represents the hypotenuse while A and B are interchangeable. So solving for the hypotenuse would look like √a^2+ b^2= c but solving for a or be would look like √c^2-b^2 = a and √c^2-a^2= b.

So number wise √5^2+12^2 = 13

3. An elevator is moving upward with a speed of 14.3 m/s . Two seconds later, the elevator is still moving upward, but its speed

By definition of average acceleration,

<em>a</em> (average) = (3.7 m/s - 14.3 m/s) / (2.0 s) = -5.3 m/s²
