The Four Vertices Of A Parallelogram Are (3,2) (6,3) (9,6) And (a,B) Find A And B
Answer 2
If we label the points A(3,2) B(6,3) C(9,6) and D(a,b)
To get from A to B we can move 3 right and 1 up
If the parallelogram was labelled anticlockwise then
to get from C the D we need to go 3 left and 1 down
This would make D the point (9 - 3, 6 - 1) = (6,5)

AB || DC because both have a slope of 1/3 [because (3 - 2)/(6 - 3) = (6 - 5)/(9 - 6)]
AD || BC because both have a slope of 1 [because (5 - 2)/(6 - 3) = (6 - 3)/(9 -6)]

You could make D (12,7) but then the corners would not be labelled in order which is the accepted method
In this case the slopes of AC and BD both be 2/3 [because (6 - 2)/(9 - 3) = (7 - 3)/(12 - 6) = 4/6]

What is the measure of 2x?

Answers

Answer:

130 °

....................

Hi! I'm happy to help!

To solve this, we need to first solve for x.

The total of all the interior angles in a quadrilateral (closed, not curved, shape with 4 sides) is 360°. So, we can single out the xs by subtracting the other angles.

360-89

271

271-76

195

Now that we know that, without the other two angles, the quadrilateral is worth 195. The only 2 angles left have x in them. Since there are 3 xs, we can use this to find out our x.

3x=195

Now, divide both sides by 3.

x=65

Now that we have the value of x, the measure of 2x will just be double that.

65×2

130

The measure of 2x is 130°

What is 48% of 159 express your answer rounded correctly to one decimal place

Answers

Answer:

.48 * 159 = 76.32

Step-by-step explanation:

48%
=0.48

Step 2: multiply to find the percent
0.48*159=76.32

So 48% of 159 is 76.32

Step 3: Round to the nearest tenth (assuming the one decimal place means tenth place)

76.32
=76.3

For what values of k will the equation 4x² + 8x + k = 0 have two real solutions?

Answers

Answer:

k < 4

Step-by-step explanation:

Given a quadratic equation in standard form

ax² + bx + c = 0 ( a ≠ 0 )

Then the discriminant Δ = b² - 4ac informs us about the nature of the solutions.

• If b² - 4ac > 0 then 2 real and distinct solutions

• If b² - 4ac = 0 then 1 real and repeated solution

• If b² - 4ac < 0 then no real solutions

4x² + 8x + k = 0 ← is in standard form

with a = 4, b = 8 , c = k , then

b² - 4ac = 8² - (4 × 4 × k) = 64 - 16k

For two real solutions

64 - 16k > 0 ( subtract 64 from both sides )

- 16k > - 64

Divide both sides by - 16, reversing the symbol as a result of dividing by a negative quantity.

k < 4

Then any value less than 4 will ensure the equation has two real solutions
