Use pythagorena theorme

D=\sqrt{(x1-x2)^{2}+(y1-y2)^{2}}
NOTE: x1 and x2 means the first x and second x, not x^1 and x^2

points given are
(1,1)
(5,6)
x1=1
y1=1
x2=5
y2=6
D=\sqrt{(1-5)^{2}+(1-6)^{2}}
D=\sqrt{(-4)^{2}+(-5)^{2}}
D=\sqrt{16+25}
D=\sqrt{41}

What is the midpoint of the line segment with endpoints ( 3.5,2.2) and (1.5,-4.8)?
Fantom [35]

Answer:

Option A) (2.5,-1.3) is correct

The midpoint of the given line segment is M=(2.5,-1.3)

Step-by-step explanation:

Given that the line segment with end points (3.5, 2.2) and (1.5, -4.8)

To find the mid point of these endpoints midpoint formula is M=\left(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\right)

Let (x_1,y_1) be the point (3.5, 2.2) and (x_2, y_2) be the point (1.5, -4.8)

substituting the points in the formula

M=\left(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\right)

M=\left(\frac{3.5+1.5}{2}, \frac{2.2-4.8}{2}\right)

=\left(\frac{5}{2}, \frac{-2.6}{2}\right)

=\left(2.5,-1.3\right)

Therefore M=(2.5,-1.3)

The midpoint of the given line segment is M=(2.5,-1.3)

USE the RULE (x,y) -----&gt; (x - 2, y - 4) to graph the image of this rectangle.
Olin [163]
So for example B(4,1) so x=4, y=1
->B'(4-2,1-4)
->B'(2,-3)

->A'(1-2,1-4)
->A'(-1,-3)

->C'(4-1,-2-4)
->C'(3,-6)

->D'(1-2,-2-4)
->D'(-1,-6)

so the image of the rectangle ABCD->A'B'C'D'

Please help!! I’m stuck on this
beks73 [17]

Answer:

B.  x = -4\,\lor \,x = -1

Step-by-step explanation:

Let \sqrt{-4-5\cdot x} = x, we solve for x by algebraic means.

1) \sqrt{-4-5\cdot x} = x Given

2) -4-5\cdot x = x^{2} Definition of power/Symmetry of equality

3) x^{2}+5\cdot x + 4 = 0 Compatibility with addition/Commutative and associative properties/Existence of additive inverse/Modulative property

4) (x+4)\cdot (x+1) = 0         x^{2}+(a+b)\cdot x +a\cdot b = (x + a)\cdot (x+b)

5) x = -4\,\lor \,x = -1 Result

Hence, the correct answer is B.
