find the value of x for which abcd must be a parallelogram

a) 9
b)18
c) 1
d)2

Missing part of question

(a) (-3, 4) and (5, 4)

(b) (4, 5) and (4, -3).

Answer:

(a) (-3, 4) and (5, 4)

Zero slope

Horizontal line

(b) (4, 5) and (4, -3).

Undefined slope

Vertical line

Step-by-step explanation:

Solving (a): (-3, 4) and (5, 4)

Slope (m) is calculated as:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

This gives

[tex]m = \frac{4-4}{5 - -3}[/tex]

[tex]m = \frac{0}{8}[/tex]

[tex]m = 0[/tex]

This line has a slope of zero.

When slope equals 0, then the line is horizontal

Solving (b): (4, 5) and (4, -3)

Slope (m) is calculated as:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

This gives

[tex]m = \frac{5--3}{4-4}[/tex]

[tex]m = \frac{8}{0}[/tex]

m = undefined

This line has an undefined slope.

When the slope of a line is undefined, then the line is vertical

Answer:

$96.55

Step-by-step explanation:

The computation of the money he would require is shown below:

Since lee wants to buy both pairs of shoes and the two pairs of socks

So the amount of money he needed is

= $37.07 + $42.48 + 2 × $8.50

= $37.07 +  $42.48 + $17

= $96.55

Answer:

30 degrees.

Step-by-step explanation:

A triangle has 180 degrees. The two base angles are 75 degrees each. The third angle is x

75 + 75 + x = 180          Combine like terms on the left

150 + x = 180                Subtract 150 from both sides.

-150         -150

x = 30

The third angle is 30 degrees.

Answer:

6 inches

Step-by-step explanation:

The mode is the most frequently occurring number.

The mode of Martha's Fish is 21.

The mode of Jamie's Fish is 15.

21 - 15 = 6

The mode of Martha's fish is 6 inches longer than the mode of Jamie's fish.

Answer:

A) $840

Step-by-step explanation:

15•40 gives us how much money he makes a week normally

divide the result, 600, by 5 to find out how much he makes a day normally which is $120

now that we know how much he normally makes a day we can double $120 to $240 to show how much he makes on holiday days

so he makes $120 normally and $240 on holiday

120•3= 360

240•2= 480

then add

360+ 480= $840

Answer:

All the measurements are correct

Step-by-step explanation:

What we have here are right triangles

For right triangles, the square of the hypotenuse (the side facing the right angle) equals the sum of the squares of the two other sides

Starting from the left;

a) 13^2 = 12^2 + 5^2

169 = 144 + 25

169 = 169

This triangle is valid

b) 25^2 = 24^2 + 7^2

625 = 576 + 49

625 = 625

This triangle is valid

c) 5^2 = 3^2 + 2^2

25 = 9 + 16

25 = 25

Step-by-step explanation:

90=x+6+3x-4

90=4x+2

88=4x

/4    /4

x=22

3(22)-4=66-4=62

22+6=28

180-28=152

Answer:

x=8/3

Step-by-step explanation:

2(3-(2x+4))-5(x-7)=3x+1 (first distribute)

-9x+33=3x+1 (subtract 33 from both sides)

-9x=3x-32 (subtract 3x from both sides)

-12x =-32 (divide both sides by -12)

x=8/3

Answer:

r = 8

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to 3

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (4, - 6) and (x₂, y₂ ) = (r, 6)

m = [tex]\frac{6+6}{r-4}[/tex] = [tex]\frac{12}{r-4}[/tex] , then

[tex]\frac{12}{r-4}[/tex] = 3 ( multiply both sides by (r - 4))

12 = 3(r - 4) ← divide both sides by 3

4 = r - 4 ( add 4 to both sides )

8 = r

Answer:

A. Y = 144/x

Step-by-step explanation:

Inversely means y = 1/x

If y = 48, when x = 3

so 144/3 = 48

Therefore the answer is A

If the  value of y varies inversely with x then the function Y= 144/x represents the relationship between x and y if y = 48 when x = 3

A relation is a function if it has only One y-value for each x-value.

If y varies inversely with x, it means that y is inversely proportional to x, or y=k/x, where k is a constant of proportionality.

To find k, we can use the given values of y and x:

y = k/x

48 = k/3

k = 144

Now that we know k, we can write the function that represents the relationship between x and y:

y = 144/x

Therefore, if the  value of y varies inversely with x then the function Y= 144/x represents the relationship between x and y if y = 48 when x = 3
