\dfrac{2}{5},\dfrac{13}{15},\dfrac{3}{5},\dfrac{1}{5},\dfrac{1}{5}

step-by-step explanation:

The intersection of two sets A and B, denoted by A ∩ B, is the set containing all elements of A that also belong to B.

The union (denoted by ∪) of a collection of sets is the set of all elements in the collection.

P(s) of a set s is defined as ratio of number of elements in s to the number of elements in universal set

given Universalset=\{\text{2,3,4,5,6,7,8,9,12,13,14,16,20,22,56}\}

given A=\{9,12,13,20,22,56\} and H=\{4,5,8,9,16,22\}

and C=\{1,4,20,22,56\}

For Question A:

A∩H=\{9,12,13,20,22,56\} ∩ \{4,5,8,9,16,22\}

=\{9,22}\}

(A∩H)∪C=\{9,22}\} ∪ C=\{1,4,20,22,56\}=\{1,4,9,20,22,56\}

p((A∩H)∪C)=\frac{6}{15}=\frac{2}{5}

For Question B:

H∩C=\{4,22\}

p(H∩C)'=\frac{15-2}{15}=\frac{13}{15}

For Question C:

p(H)'=\frac{15-6}{15}=\frac{3}{5}

For Question D:

C\H=\{1,20,56\}

p(C\H)=\frac{3}{15}=\frac{1}{5}

For Question E:

A\C=\{9,12,13\}

p(A\C)=\frac{3}{15}=\frac{1}{5}

Triangle DIG is reflected across the l-axis.
drek231 [11]

there is not such thing as an I axis, but I will show you what happens for both x and y axis so you can fill out the assignment with the correct information.

IF you meant flipping over the x axis, then the dot will go from top to bottom, bottom to up, the x position won't change only its height(y position)

This meant that for reflecting across the x axis, (x,y)->(x,-y)

For y axis its the opposite, just flipping to the side.

This meant that for reflecting across the y axis, (x,y)->(-x,y)

Show that the statement is true. If GH has endpoints G(−2, 1) and H(4, −1), then the midpoint M of GH lies on the line y = −x +
Alex777 [14]
Midpoint = (x1 + x2) / 2, (y1 + y2)/2
(-2,1)....x1 = -2 and y1 = 1
(4,-1)...x2 = 4 and y2 = -1
time to sub
m = (-2 + 4) / 2 , (1 + (-1) / 2
m = (2/2), (0/2)
m = (1,0) <==

y = -x + 1.....(1,0)...x = 1 and y = 0
0 = -1 + 1
0 = 0 (correct)

so the midpoint  M (1,0) lies on the line since its coordinates satisfy the equation <===

X=(y)/(y-3) make y the subject
Liula [17]

Answer:

\displaystyle y=\frac{3x}{x-1}

Step-by-step explanation:

<u>Solving Equations</u>

We have the expression:

\displaystyle x=\frac{y}{y-3}

And it's required to make y the subject.

It can be done by isolating y on the left side of the equation and the rest of the expression on the right side.

The first step is removing the denominator by multiplying both sides by y-3:

\displaystyle (y-3)x=(y-3)\frac{y}{y-3}

Simplifying the right side:

\displaystyle (y-3)x=y

Remove the parentheses:

yx-3x=y

Move the y's to the left side and the rest of the expression to the right side:

yx-y=3x

Factor out y:

y(x-1)=3x

Divide by x-1:

\mathbf{\displaystyle y=\frac{3x}{x-1}}

Triangle has 180 degrees:
180=2m-3+m+4+3m+5
Combine like terms
180 = 6m+6
Subtract 6 from 180
174=6m
Divide by 6
m=29
