Answer:

i) Cost = $37.5

ii) Profit = $7.5

Loss = -$12.5

Step-by-step explanation:

i) If Halim's profit selling the pair of shoes of $45 is 120%, to find the cost pricer of the pair of shoes, we just need to divide the value by the profit:

Cost = 45/120% = 45/1.2 = $37.5

ii) To find his profit, we just need to subtract the selling value by the cost price:

Profit = 45 - 37.5 = $7.5

The loss that he would have if he sells the pair of shoes at $25 is:

Loss = 25 - 37.5 = -$12.5

Answer:

a. $20.45

b. $24.55

c. $4.55

Step-by-step explanation:

In this question, we are asked to calculate the cost price and profit or loss selling a pair of shoes.

we proceed as follows

Firstly, we want to find the cost price given the selling price and the mark up percentage.

mathematically;

profit =( selling price - cost price)/cost price * 100%

here our profit is 120% with the cost price being $45. we plug these values

120 = 45-cp/cp * 100%

120cp = 100(45-cp)

120cp = 4500 -100cp

220cp = 4500

cp = 4500/220 = $20.45

His profit is selling price - cost price = 45 - 20.45 = $24.55

His profit selling same shoe for $25 is 25-20.45 = $4.55

Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.

Answer:

1) y = 2x + 1

y = x + 2 Corresponding with the third graph

2) y = 3x

y = x + 3 Corresponds with the first graph

3) y = 2x - 2

y = x - 2

4) y = 2x + 3

y = x + 5

Likely correspond with the fourth graph

5) y = 4x + 2

y = 2x + 2 Corresponding with the second equation

Step-by-step explanation:

The groups of equation are;

1) y = 2x + 1

y = x + 2

The y-intercept of equation (1) = 1

The x-intercept of equation (1) = -1/2

The slope of equation (1) = 2

So at x = 0 y = 1 and at  y = 0 x = -1/2 and at x = 2 y  = 3

Corresponding with the third graph

The same can be shown with the second equation

2) y = 3x

y = x + 3

The y-intercept of equation (1) = 0

The x-intercept of equation (1) = 0

The slope of equation (1) = 3

So at x = 0 y = 0 and at   x = 2 y  = 6

Corresponds with the first graph

The same can be shown with the second equation

3) y = 2x - 2

y = x - 2

4) y = 2x + 3

y = x + 5

Likely correspond with the fourth graph

5) y = 4x + 2

y = 3x + 2

The y-intercept of equation (1) = 2

The x-intercept of equation (1) = -1/2

The slope of equation (1) = 4

So at x = 0 y = 2 and at  y = 0 x = -1/2 and at x = 0.5 y  =  4

Corresponding with the second equation

The same can be shown with the second equation

Answers:

Slope = 3

y intercept = -20

=========================================

The two points (0,-5) and (1,-2) are on the line y = 3x-5. You can see this through a graph, or by plugging in x = 0 to get y = -5 (do the same for x = 1 to get y = -2). The point (0,-5) is the y intercept as this is where the graph crosses the y axis.

Multiply each coordinate of those two points by the scale factor 4

(0,-5) turns into (0,-20)

(1,-2) turns into (4,-8)

Find the slope of the line through the two new points (0,-20) and (4,-8). Use the slope formula.

m = (y2-y1)/(x2-x1)

m = (-8-(-20)/(4-0)

m = (-8+20)/(4-0)

m = 12/4

m = 3

Note how the slope we just found is the same as the slope of the original line. Dilations preserve slopes, so that means the image is parallel to the preimage.

Since (0,-5) became (0,-20), this means the y intercept is now b = -20

So m = 3 and b = -20 means y = mx+b becomes y = 3x-20. Plug in x = 4 and you'll find that y = -8; proving that (4,-8) is on the line y = 3x-20.
