Answer:

Px = √27 = 3√3

Step-by-step explanation:

∆Pxy is a right triangle.

Py = 6

xy = ½*6 = 3

Use pythagorean theorem to find Px.

Px = √(Py² - xy²)

Px = √(6² - 3²)

Px = √(36 - 9)

Px = √27 = 3√3

Write the equation of the line which passes through (1, 2) and with slope of −1/3
Sati [7]

Answer:

<h2>          x + 3y = 7            </h2>

Step-by-step explanation:

The equation of a line which passes through <em>(x₁, y₁)</em> and with slope of <em>m</em> in point-slope form:

                                y - y₁ = m(x - x₁)

m = -¹/₃

(1, 2)    ⇒   x₁ = 1,  y₁ = 2

Therefore,  the equation of the line which passes through (1, 2) and with slope of −1/3 in point-slope form:

y - 2 = -¹/₃(x - 1)

y - 2 = -¹/₃x + ¹/₃                     {add ¹/₃x to both sides}

¹/₃x + y - 2 = ¹/₃                     {add 2 to both sides}

¹/₃x + y = 2¹/₃                       {multiply both sides by 3}

x + 3y = 7

Give me the answer for question 3 please
Paha777 [63]
Try calculating each of these yourself: 

<span>First, 34(58 + 9) = 34(67) = 2278 </span>

<span>A. 34 x 67 = 2278 </span>

<span>B. 58(34 + 9) = 58(43) = 2494 </span>

<span>C. 34 x 58 + 34 x 9 = 34 x (58 + 9) = 34 * 67 = 2278 </span>

<span>D. 1,972 </span>

<span>So the answer is B and D are not equal to 34(58 + 9).

Hope I helped! If you need anything else just ask!</span>
