1/3 x + 1 = 5/6 x - 3

Answers

Answer:

x=8

Step-by-step explanation:

Step 1: Subtract 5/6x from both sides.

1/3x+1−5/6x=5/6x−3−5/6x

−1/2x+1=−3

Step 2: Subtract 1 from both sides.

−1/2x+1−1=−3−1

−1/2x=−4

Step 3: Multiply both sides by 2/(-1).

(2/−1)*(−1/2x)=(2/−1)*(−4)

x=8

18w2(squared) - w - 39​

Answers

Answer:

w = 1.5 and -1.44

Step-by-step explanation:

Given the quadratic equation 18w^2 - w - 39

Using the general formuls

w = 1 ±√1²-4(18)(-39)/2(18)

w =1 ±√1+2808/36

w =1 ±√2809/36

w = 1+53/36 and 1-53/36

w  = 54/36 and -52/36

w = 1.5 and -1.44

What is a trapezoid?

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a trapezoid, one pair of opposite sides are parallel.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

In the isosceles trapezoid, the sum of the opposite angle is 180 degrees. Then the equation is given as,

∠NMQ + ∠NPQ = 180°

∠NPQ + 32° + 30° = 180°

∠NPQ = 118°

The measure of the angle ∠NPQ will be 118°. Then the correct option is C.

What is this exactly?

Step-by-step explanation:

What is the y-intercept of the line that passes through the points (2,-1) and (-3,9)

Answers

Answer:

The equation of the straight line y = -2x +3

y-intercept =  3 and m =-2

Step-by-step explanation:

Step(i):-

Given that the points are ( 2,-1) and (-3,9)

The slope of the line

[tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{9-(-1)}{-3-(2)} = \frac{10}{-5} = -2[/tex]

Step(ii):-

The equation of the straight line passing through the point ( 2,-1) and slope m=-2

      y-y₁ = m( x- x₁)

     y -(-1) = -2 ( x-2)

      y +1 = -2x +4

     2x +y +1-4 =0

    2x +y -3 =0

Final answer:-

The equation of the straight line y = -2x +3
