Write an equation for the line that passes through the given point and is parallel to the graph of the given equation.
vova2212 [387]

Answer:

\displaystyle 2x - 3y = 6\:OR\:y = \frac{2}{3}x - 2 \\ \\ 3x - 2y = 40\:OR\:y = \frac{3}{2}x - 20

Step-by-step explanation:

2 = ⅔[6] + b

4

\displaystyle -2 = b \\ \\ y = \frac{2}{3}x - 2

If you want it in <em>Standard Form</em>:

y = ⅔x - 2

- ⅔x - ⅔x

_________

−⅔x + y = −2 [We do not want fractions in our standard equation, so multiply by the denominator to get rid it.]

−3[−⅔x + y = −2]

\displaystyle 2x - 3y = 6

_______________________________________________

−5 = 3⁄2[10] + b

15

\displaystyle -20 = b \\ \\ y = \frac{3}{2}x - 20

If you want it in <em>Standard</em><em> </em><em>Form</em>:

y = 3⁄2x - 20

- 3⁄2x - 3⁄2x

__________

−3⁄2x + y = −20 [We do not want fractions in our standard equation, so multiply by the denominator to get rid of it.]

−2[−3⁄2x + y = −20]

\displaystyle 3x - 2y = 40

* Parallel Lines have SIMILAR <em>RATE OF CHANGES</em> [<em>SLOPES</em>], so ⅔ and 3⁄2 remain the way they are.

3. tan(α) = height/distance
distance = height/tan(α)
distance = (648 m)/tan(13°) ≈ 1399.5 m

6. when y = |x| is translated 6 units down, 6 is subtracted from the y-value:
.. y = |x| -6

10. In point-slope form, the line through point (h, k) with slope m is
.. y -k = m(x -h)
For (h, k) = (10, -9) and m = -2, you have
.. y +9 = -2(x -10)

(3_4sin²a) (sec²_4tan²a) =(3-tan²a)(1-4sin²a)<br>​
jonny [76]

Answer:

Being male and preferring brand A are independent.

Because: if independent then P(male and brand A) = P(male) P(brand A) = 0.48 * 0.75 = 0.36 and that is true (= value in the table)  

P(male|brand A)=0.36/0.75=0.48 = P(male)

So the two answers are:

(1) "independent"

(2) =

Solve for y then find the value of x. y+6x=11;x=-1,0,3
Brrunno [24]

Answer:

Solution for y is y = 11 - 6x

For x = -1, the y value is 17

For x = 0, the y value is 11

For x = 3, the y value is -7

Step-by-step explanation:

Solve for y --> y + 6x = 11

y + 6x = 11

  -6x      -6x

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

y = 11 - 6x

Plug -1, 0, and 3 into this equation to find values of y --> x = 11 - y / 6

When x is -1, the y value becomes 17. Secondly, when x is 0, the y value becomes 11. Thirdly, when x is 3, the y value becomes -7.
