Step-by-step explanation:

Option D is the correct answer

Because if the blouse is of 8 dollars then 4 blouses = 32 and skirt = 12 so 3 skirts = 36

36 + 32 = 68

Susan bought 6 blouses = 8 x 6 = 48

3 skirts = 12 x 3 = 36

48 + 36 = 84

Answer:

Graph A → Equation A → Table B → Property D

Graph D → Equation B → Table A → Property B

Graph B → Equation C → Table C → Property E

Graph C → Equation D → Table E → Property A

Graph E → Equation E → Table D → Property C

Step-by-step explanation:

Graph A corresponds to equation A, x·y = 2, and Table B → Property D

xy = 2 has a vertical asymptote at x = 0, and a horizontal asymptote at y = 0

y = 2/x, when x = 0, y = ∞

Graph D corresponds to equation B, -\left |  x\right | + 1 which corresponds to table A → Property B

The domain extends from (-∞, ∞), and [1, -∞)

Graph B corresponds to equation C, -(x + 2)² which gives the values in Table C and Property E wich is a horizontal shift of 2 units left and a reflection across the x-axis

Graph C corresponds to equation D, (1/3)·x - 2, which gives the values on Table E and Property A

The y-intercept of (1/3)·x - 2 = (0, -2), and the x-intercept = (6, 0)

Graph E corresponds to equation E, x³ = y, which gives the values on Table D  Property C, y is x cubed

5. What is BC?<br> 4x - 8<br> 2x + 12<br> 3x + 4
borishaifa [10]

Answer:

BC = 34

Step-by-step explanation:

Given that ∠B = ∠C then the triangle is isosceles.

Thus AB and AC are congruent, that is

4x - 8 = 2x + 12 ( subtract 2x from both sides )

2x - 8 = 12 ( add 8 to both sides )

2x = 20 ( divide both sides by 2 )

x = 10

Hence

BC = 3x + 4 = (3 × 10) + 4 = 30 + 4 = 34

A circle has a central angle measuring 3pi/4 radians that intersects an arc of length 45 in. What is the length of the radius of
goldfiish [28.3K]
Central angle = 3π / 4 radians

Length of the arc = (3 π / 4) (radius) = 45 in

=> radius = 45 in * 4 / (3π) = 45 * 4 / (3 * 3.14) in

radius = 19.1 in

Answer: 19.1 in
