How do I figure the equation out
Tatiana [17]

Answer:

<em><u>Answer for Parallel line:</u></em> y = 3x - 13

<em><u>Answer for Perpendicular line: </u></em>y = (-1/3)x +17/3

Step-by-step explanation:

<em><u>Parallel line</u></em>

For the slope of a line parallel to another (given) line, just read the slope of the given line. It (in this case) is the coefficient in front of the x.

m = 3

So far what you have is y = 3x + b

To find b, use the given point (2,5)

x = 2

y = 5  Substitute these values into the skeletal equation. y = 3x + b

2 = 3*5 + b     Subtract 15 from both sides.

2 = 15 + b

2 - 15 = b switch sides

b = - 13

Answer y = 3x - 13

Part B

<em><u>Perpendicular line</u></em>

The perpendicular line will have a slope determined by the following formula

m1 * m2 = - 1

m1 is the slope of the given line which is 3

3 * m2 = - 1

m2 = - 1/3

So far, what you have is

y = (-1/3)x + b To find b, use the same 2 givens as above.

y = 5

x = 2

Substitute into the skeletal equation.

5 = (-1/3)(2) + b

5 = -2/3  + b  Switch sides.  

b - 2/3 = 5  Add 2/3 to both sides.

b = 5 + 2/3

b = 5 2/3 = 17 / 3

Answer

y = (-1/3)x + 17/3

If this doesn't seem right, and you have choices, could you please list them?

Can anybody help me out with this problem pleaseee :D
Oksanka [162]
<h3>Answer: 10</h3>

Explanation:

"percent" means "per one hundred". Think "cent" as in "100 cents in a dollar". That's one way to remember.

So when we say something like 2%, we mean 2 out of 100 leading to the fraction 2/100 = 0.02

The same applies for 4.8% turning into 4.8/100 = 0.048

A quick shortcut without the use of a calculator has us move the decimal point 2 spots to the left to go from 4.8% to 0.048

-------------

After converting 4.8% to 0.048, we then multiply this by 200

200*(0.048) = 9.6

this value rounds to 10 which is the answer
