Integers are set of whole numbers <em>and </em>their counterparts, for example:

..., -3, -2, -1, 0, 1, 2, 3, ...

If the given integer is below 0, then its opposite will be positive. Let's check it on the example:
 
Opposite of 5 is -5 (so Cindy is right here)
But opposite of -5 is 5 (so she's wrong)

Find the equation of the line passing through(1,2) and making an angle of 30 degree with y intercept
olya-2409 [2.1K]

Answer:

Equation of the straight line passing through the point ( 1,2 ) and having the slope

 x - √3y -1+2√3 =0

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that the point (1,2) and an angle = ∝ = 30°

The slope of the line

             m = tan 30°

             m = \frac{1}{\sqrt{3} } }

<u><em>Step(ii)</em></u>:-

Equation of the straight line passing through the point ( 1,2 ) and having the slope

 m = \frac{1}{\sqrt{3} } }

           y - y₁ = m(x-x₁)

          y - 2 = \frac{1}{\sqrt{3} } } ( x -1)

        √3(y-2) = (x-1)

⇒       √3y - 2√3 = x -1

           x - √3y -1+2√3 =0

To Find: How much will a home that cost $150,000 be worth 3 years later?

Solution:

Principal = $150000

Rate = 13% =0.13

Time = 3 years

Formula : A=P(1+r)^t

Now substitute the values in the formula

A=150000(1+0.13)^3

A=216434.55
