please answer please!!!! Will mark brainliest for complete answer. -the first photo is to calculate the area. Just question number 7 a and b i). And question number 8.

Answer:

the mark-up is $10 or 20% of the original price.

Step-by-step explanation:

This is because 60-50 is 10. And 20% or 1/5 of 50 is 10.

1). Slope = (-2)

2). Midpoint = (2, -2)

3). Slope of the perpendicular bisector = (1/2)

4). Equation of perpendicular bisector will be x - 2y = 6

Step-by-step explanation:

A line segment has the endpoints at (4, -6) and (0, 2).

1). Then the slope of the given line segment will be = (y - y')/(x - x') = (2 + 6)/(0 - 4) = 8/(-4) = (-2)

2). Mid point of the line segment is given by

Therefore midpoints of the line segment will be  = (2, -2)

3). Slope of the perpendicular bisector is represented by

⇒ (-2)×m2 = (-1)

⇒

4). Now we have to find the equation of perpendicular bisector passing through (2, -2) and slope (1/2).

Since standard equation of the line will be given as y = mx + c

passes through (2, -2).

c = (-1) - 2 = -3

Finally the equation of perpendicular bisector will be

⇒ 2y = x - 6

⇒ 2y - x = -6

⇒ x - 2y = 6

Answer: linear/first degree

Step-by-step explanation:

 (6-t-t^4)+(9t+t^4)

=6-t-t^4+9t+t^4

=8t+6

The degree of a polynomial is determined by the highest degree in the polynomial. The highest degree in this binomial is one, which is first degree or known as linear.

Step-by-step explanation:

Answer:

No solution.

Step-by-step explanation:

 x - 3y - 3 = 0

3x - 9y - 2=0

Multiply the first equation by - 3:

-3x + 9y + 9 = 0

Add this to the second equation:

0 + 0 + 7 = 0

0 = -7  , which is absurd so there is no solution to this system.

Answer:

Area = (x² + 11x + 24)

Step-by-step explanation:

Area of the blue square with sides 'x' units = (Side)²

                                                                       = x²

Area of the pink rectangle = Length × width

                                            = 3 × (x)

                                            = 3x

Area of the orange rectangle = Length × Width

                                                 = 8 × 3

                                                 = 24

Area of the green rectangle = Length × width

                                               = (x) × 8

                                               = 8x

Now total area of the entire rectangle = x² + 3x + 24 + 8x

                                                                = (x² + 11x + 24)

Therefore, area of the entire rectangle will be a polynomial (x² + 11x + 24)

Answer:

The rule for the plotted line is [tex]y = \left | x - 50 \right |[/tex]

Step-by-step explanation:

The coordinates when y = 0, x = 50

When y = 10, x = 60

Therefore, the slope = (10 - 0)/(60 - 50) = 1

The equation in slope and intercept form is y - 10 = 1 × (x - 60)

y = x -60 + 10 = x -50

y = x - 50

Also, we have

When y = 20, x = 30

y = 10, x = 40

Therefore, the slope = (10 - 20)/(40 - 30) = -1

The equation in slope and intercept form is y - 10 = -1 × (x - 40)

y = -x + 40 + 10

y = 50 - x

Therefore, when x < 50, y = 50 - x

When x > 50, y = x - 50

Which is equivalent to [tex]y = \left | x - 50 \right |[/tex]

The rule for the plotted line is [tex]y = \left | x - 50 \right |[/tex]

Answer:

The answer is

Step-by-step explanation:

In order to solve this question we use ratio and proportion.

From the question

$ 2.50 is the price of one gallon

To find the number of gallons that cost $16.2 , multiply $16.2 by one gallon and divide it by $ 2.50

That's

[tex] \frac{16.2 \times 1}{2.50} [/tex]

= 6.48

We have the final answer as

6 gallons

Answer:

D

Step-by-step explanation:

The tangent- tangent angle x is half the difference of the intercepted arcs.

The sum of the 2 arcs on the circle = 360°, thus

lower arc = 360° - 243° = 117°, then

x = [tex]\frac{1}{2}[/tex] (243 - 117)° = 0.5 × 126° = 63°

Answer:

24x-320

Step-by-step explanation:

Area of a rectangle is length*width.

This basically means we have to multiply one of its sides with the other side.

Hence, our expression would be:

8(3x-40)

Simplify by distributing.

8*3x+8*-40

24x-320

The area of the rectangle is 24x-320.
