Answer:

Option C.

Step-by-step explanation:

If a line passes through two points (x_1,y_1) and (x_2,y_2), then the rate of change is

m=\frac{y_2-y_1}{x_2-x_1}

From the given graph it is clear that the line passes through the points (0,20) and (10,50). So, the slope of the lien is

m=\frac{50-20}{10-0}=\frac{30}{10}=3

The slope of two parallel lines are same. So, the slope of parallel line is 3.

The point slope form of a line is

y-y_1=m(x-x_1)

The slope of parallel line is 3 and it passes through the point (4,15). So, the equation of parallel line is

y-15=3(x-4)

Using distributive property

y-15=3x-12

Add 15 on both sides.

y=3x-12+15

y=3x+3

The required equation is y=3x+3. Therefore, the correct option is C.

A sold a commodity to b at 10% profit b again sold it to a at 10% loss. What does a have
ozzi
Let's answer this step-by-step.

First of all, let's estsblish the original price of the commodity as being 100%. Therefore:

Original price of commodity = 100%

Then, when A sold the commodity to B, it was sold at a 10% profit. Therefore:

Price of commidity when A sold to B:
100% x 1.1 = 110%

After that, when B sold it back to A, it was sold at a 10% loss. Therefore:

Price of commodity when B sold to A:
110% x 0.9 = 99%

Hence, A now has 99% of the original value of the commidity.
