Answer:
The solution set is (2,4).
Step-by-step explanation:
Given that:
−2x + 2y =4 Eqn 1
−4x + 8y =24 Eqn 2
Multiplying Eqn 1 by -2
-2(-2x+2y=4)
4x-4y= -8 Eqn 3
Adding Eqn 2 and 3
(-4x+8y)+(4x-4y)=24-8
-4x+8y+4x-4y=16
4y=16
Dividing both sides by 4
Putting y=4 in Eqn 1
-2x+2(4)=4
-2x+8=4
-2x=4-8
-2x=-4
Dividing both sides by -2
Hence,
The solution set is (2,4).

Each co-worker can get 3 whole boxes, there is one half left over
Hey there,
The slope is the rise over the run of a line right?
And the formula is y2-y1 as the numerator and x2-x1 as the denominator.
So in this case the two xs are 1 and 2 right?
And the denominator is the second denominator is the second x minus the first x right?
In this case the second x is 2 roght?
And the first x is 1.
So it’s 2-1 which is 1.
So the answer is x2-x1 which is 1
Hope this helps
Answer:
see below
Step-by-step explanation:
-90 degrees, the rule is (x, y) --------> (-y, x)
The leftmost point is at (1,1) so it will be at (-1, 1)
The top right point is at (4,1) so it will be at (-1,4)
The bottom right point is at (4,-1) so it will be at (1,4)
