(x1,y1)
(x2,y2)
(xm,ym)
Midpoint formula is given as below.
((x1 + x2)/2 , (y1 + y2)/2 )
Where
(x1 + x2)/2 = xm ----------- (1)
(y1 + y2)/2 = ym ----------- (2)
Equation (1) implies that;
x1 + x2 = 2xm
x2 = 2xm – x1
Equation (2) implies that;
y1 + y2 = 2ym
y2 = 2ym – y1
Thus the end point is
<span>(x2,y2) = (2xm – x1, 2ym – y1)</span>
Answer: 16y² - x²
Step-by-step explanation: The - sign means a difference, so the choices with + signs are eliminated (though 64x² and 9 are squares)
10 is not a square so that one is eliminated (though the y² and the 4x² are squares)
16 is the square of 4, y² is the square of y, and x² is the square. That expression shows a difference of squares.
Answer:
x=16 y=38
Step-by-step explanation:
x+y=54.......equation 1
x=y-22........ equation 2
substitute
y-22+y=54
2y-22=54
2y=54+22
2y=76
y=76/2
y=38''
x=y-22
x=38-22
x=16''
Answer:e
Step-by-step explanation:n
Answer:
530 grams
Step-by-step explanation:
970 grams = 0.970 kg
1 kg = 1000 grams
Thus: 500+30 = 530 grams
