Answer:

x=4

Step-by-step explanation:

The left and right sides are equal so:

5x-2 + 4x = 7x-4 + x+6

Collect the like terms and calculate the sum :

9x-2 = 8x+2

Move terms and change it's sign:

9x-8x = 2+2

And finally:

x=4

Also if you solve the equations of the other sides you'll find x₁=0.5 and x₂=4

which the intersection with the previous answer will be x=4

Point B is reflected over the y-axis to create the point B'. Then, points B, B' and C are connected to form a triangle. What is the area of the triangle formed? 48 square units 14 square units 28 square units 24 square units

Answers

Answer:

24 square units

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation translation and dilation.

If a point O(x, y) is reflected along the y axis, the new location would be O(-x, y).

The coordinate of the triangle is B(3, 5), C(3, -3). Therefore since B is reflected along y axis to form B'. Hence, B' = (-3, 5)

[tex]|BC|=\sqrt{(3-3)^2+(5-(-3))^2}=8\ units \\\\|CB'|=\sqrt{(-3-3)^2+(5-5)^2}=6\ units \\\\Area\ of\ triangle\ BCB'=\frac{1}{2}* |BC|*|BB'|=0.5*8*6\\\\Area\ of\ triangle\ BCB'=24\ units[/tex]

1. Triangle QRS has a perimeter of 55. If RT bisects angle R, what is the length of QT?


a. 10

b. 12

c. 15

d. 18

Answers

Answer:

[tex]QT = 10[/tex]

Step-by-step explanation:

Given

[tex]Perimeter = 55[/tex]

See attachment for triangle

The perimeter is calculated as:

[tex]Perimeter = QR + RS + QS[/tex]

This gives:

[tex]55 = 3x + 18 + 2x +12[/tex]

Collect like terms

[tex]3x + 2x = 55 - 18 - 12[/tex]

[tex]5x = 25[/tex]

[tex]x = 5[/tex]

From the attachment:

[tex]QT = 2x[/tex]

[tex]QT = 2 * 5[/tex]

[tex]QT = 10[/tex]

Triangle QRS has a perimeter of 55. If RT bisects angle R, then the length of QT is 10 and this can be determined by using the formula of the perimeter of a triangle.

Given :

Triangle QRS has a perimeter of 55.RT bisects angle R.QS = 2x +12QR = 3xRS = 18

The perimeter of the triangle QRS is given by:

Perimeter = QR + RS + QS

55 = QR + RS + QS

Now, put the values of sides QR, RS, and QS in the above equation.

55 = 3x + 18 + 2x + 12

55 = 5x + 30

25 = 5x

x = 5

Now, the length of the QT is given by:

QT = 2x

QT = 10

7. No Broken Hearts [2.5 Points]Robert has a standard deck of 52 playing cards. Robert shuffles the deck, draws a card, andchecks if the card has a suit of hearts. If the card has a suit of hearts he stops. Otherwise,he replaces the card back into the deck and continues to repeat this process until he drawsa card that has a suit of hearts.a) What is the probability that Robert performs exactly 5 draws

Answers

Answer:

0.079

Step-by-step explanation:

Number of suit of hearts = 13

Total number of cards in deck = 52

P(drawing a suit of heart) = number of suit of heart / total number of cards in deck

P(drawing a suit of heart) = 13 /52 = 1 /4

Hence, Probability of success, p = 1/4

P(not drawing a suit of heart) = 1 - 1/4 = 3/4

Hence, Probability of performing exactly 5 draws :

To perform exactly 5 draws :

1st draw = not a heart suit

2nd draw = not a heart suit

3rd draw = not a heart suit

4th draw = not a heart suit

5 draw = a heart suit

P(performing exactly 5 draws) =

(3/4 * 3/4 * 3/4 * 3/4 * 1/4)

= 0.0791015625

= 0.079
