Answer:

The standard form is -x + 2y = 8

Step-by-step explanation:

To find this, start by using point-slope form with the given information.

y - y1 = m(x - x1)

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

Now solve for the constant.

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

y - 3 = 1/2x + 1

-1/2x + y - 3 = 1

-1/2x + y = 4

Now to get integers, multiply the whole thing by 2.

-x + 2y = 8

If x and y are complementary angles, then y is a right angle. right?

Nikitich [7]

Always because the sum of x and y is 180 degrees. If x and y are right angles, then x and y are supplementary angles. Never because the sum of x and y has to be 90 degrees. If x and y are complementary angles, then y is a right angle.

5. Find cos theta if sin theta= -12/13 and tan theta > 0. (6 points)

ziro4ka [17]

$\text{Given that,}\\\\\sin \theta = -\dfrac{12}{13}\\\\\implies \sin^2 \theta = \dfrac{144}{169}\\\\\implies 1- \cos^2 \theta = \dfrac{144}{169}\\\\\implies \cos^2 \theta = 1- \dfrac{144}{169}\\\\\implies \cos^2 \theta = \dfrac{25}{169}\\\\\implies \cos \theta = \pm \sqrt{\dfrac{25}{169}} = \pm \dfrac 5{13}\\\\\\\text{Since,}~ \tan \theta >0,\\\\\cos \theta =- \dfrac{5}{13}$

Let x1 = 12, y1 = 15, and y2 = 3. Let y vary inversely with x. Find x2.

Ostrovityanka [42]

We have that an inverse variation in a function is given by:
$y = k / x
$
We must find the value of the constant k.
To do this, we substitute the values of x1 = 12, y1 = 15.
We have then:
$15 = k / 12
$
Clearing k we have:
$k = (15) * (12)

k = 180$
Substituting the value of k we have that the inverse variation is:
$y = 180 / x
$
For y2 = 3 we have:
$3 = 180 / x2
$
Clearing x2 we have:
$x2 = 180/3$
$x2 = 60$
Answer:
$x2 = 60$

Solve for x. 5x + 3 = 2(x + 3) + 3x – 6

Charra [1.4K]

9514 1404 393

Answer:

no solution

Step-by-step explanation:

We can eliminate parentheses and collect terms.

5x +3 = 2x +6 +3x -6

5x +3 = 5x

3 = 0 . . . . . . . . subtract 5x from both sides

There is no value of x that will make this true. There is no solution.
