If the uniform lists at retail cost of (c), which of the following choices would Janice use to correctly calculate her total cost (T) of the uniform?A. (T) = (c) – 0.3c + 0.08c B. (T) = 0.7c + 0.08(0.7c) C. (T) = 0.7 (0.3c + 0.08c) D. (T) = 0.7 (c – 0.08c)

What is 1/2 of 2 3/4?

Answers

Answer:

1 3/8

Step-by-step explanation:

First, change the mixed fraction to improper fraction.

2 3/4 = 8/4 + 3/4 = 11/4

1/2 of 11/4 = (11/4)(1/2) = 11/8

11/4 - 11/8 = 22/8 - 11/8 = 11/8

11/8, or 1 3/8 is your answer.

Which system of equations is represented by the graph? A. y = x2 − 5x − 3
6x − y = −27

B.y = x2 − 5x + 3
6x − y = 27

C. y = x2 + 5x + 3
6x + y = −27

D. y = x2 + 5x − 3
6x + y = 27

Answers

Answer:

The correct option is C.

Step-by-step explanation:

The vertex form of a parabola is

y=a(x-h)^2+k              .... (1)

Where, (h,k) is vertex.

From the given figure it is clear that the vertex of the parabola is at (-2.5, -3.25) and the y-intercept is (0,3).

Substitute h=-2.5, k=-3.25, x=0 and y=3 in equation (1) to find the value of a.

3=a(0+2.5)^2-3.25

3+3.25=6.25a

6.25=6.25a

Divide both sides by 6.25.

1=a

Substitute h=-2.5, k=-3.25 and a=1 in equation (1), to find the equation of parabola.

y=1(x+2.5)^2-3.25

y=x^2+5x+6.25-3.25

y=x^2+5x+3

The equation of parabola is y=x^2+5x+3.

If a line passes through two points then the equation of line is

y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1)

The line passes through two points (-6,9) and (-5,3).

y-9=(3-9)/(-5+6)(x+6)

y-9=(-6)/(1)(x+6)

y-9=-6(x+6)

y-9=-6x-36

Add 9 on both the sides.

y=-6x-36+9

y=-6x-27

The equation of line is y=-6x-27.

Therefore the correct option is C.
C. y = x2 + 5x + 3
6x + y = −27
