What is the slope-intercept form of 3x +2y=1?
klasskru [66]

Answer:

y = (-3/2)x + 1/2

Step-by-step explanation:

Note that slope intercept form = y = mx + b

Change the given equation so it matches the form:

3x + 2y = 1

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. First, subtract 3x from both sides:

3x (-3x) + 2y = 1 (-3x)

2y = -3x + 1

Next, Divide 2 from both sides:

(2y)/2 = (-3x + 1)/2

y = (-3/2)x + 1/2

y = (-3/2)x + 1/2 is your answer.

The angle \theta_1θ
enyata [817]

Answer:

sin\theta_1 = \dfrac{\sqrt{217}}{19}

Step-by-step explanation:

It is given that:

cos\theta_1 = -\dfrac{12}{19}

And we have to find the value of sin\theta_1 = ?

As per trigonometric identities, the relation between sin\theta\ and \ cos\theta can represented as:

sin^2\theta + cos^2\theta = 1

Putting \theta_1 in place of \theta Because we are given

sin^2\theta_1 + cos^2\theta_1 = 1

Putting value of cosine:

cos\theta_1 = -\dfrac{12}{19}

sin^2\theta_1 + (\dfrac{12}{19})^2 = 1\\\Rightarrow sin^2\theta_1 + \dfrac{144}{361} = 1\\\Rightarrow sin^2\theta_1 = 1-\dfrac{144}{361}\\\Rightarrow sin^2\theta_1 = \dfrac{361-144}{361}\\\Rightarrow sin^2\theta_1 = \dfrac{217}{361}\\\Rightarrow sin\theta_1 = +\sqrt{\dfrac{217}{361}}, -\sqrt{\dfrac{217}{361}}\\\Rightarrow sin\theta_1 = +\dfrac{\sqrt{217}}{19}, -\dfrac{\sqrt{217}}{19}

It is given that \theta_1 is in 2nd quadrant and value of sine is always positive in 2nd quadrant. So, the answer is.

\Rightarrow sin\theta_1 = \dfrac{\sqrt{217}}{19}

What is a closed line of credit
Vinvika [58]

You may start out with a "line of credit" agreement with a bank that allows you to create relatively small loans by the bank to yourself at a specified interest rate and under other specific terms. Of course you must repay these loans, with interest, and that's how the bank makes its money.

If you fail to repay the bank, the bank may close your account and demand that you immediately repay all the money you owe it. A "closed line of credit" is a pretty sad thing.
