Hey there!
Since it's 30n, 30 is the coefficient and it's being multiplied by n.
We plug in n.
30(2) =
60
Hope this helps!

2. Which is an equation of the line with a slope of 2 that passes through (3,-5)?
Vadim26 [7]

Answer:

y + 5 = 2(x - 3) (Answer A)

Step-by-step explanation:

Since the slope and a point on the curve are given, use the point-slope formula for the equation of a straight line:

y - k = m(x - h)

Here, m = 2, h = 3 and k = -5, so we have:

y + 5 = 2(x - 3) (Answer A)

Complete the equation of the line through (-6, 5) and (-3, -3)
statuscvo [17]

Answer:

y = -8/3x - 11

Step-by-step explanation:

(-6, 5) and (-3, -3)

Slope:

m=(y2-y1)/(x2-x1)

m=(-3-5)/(-3+6)

m=(-8)/3

m= -8/3

Slope-intercept:

y - y1 = m(x - x1)

y - 5 = -8/3(x + 6)

y - 5 = -8/3x - 16

y = -8/3x - 11

Find the value of x and y so that the quadrilateral is a parallelogram.
Mashutka [201]

Applying the properties of a parallelogram, the values of x and y are: x = 8; y = 20.9

<h3>Properties of a Parallelogram</h3>
  • The opposite sides in a parallelogram have the same length.
  • Opposite angles are equal.
  • Adjacent angles in a parallelogram are supplementary.

4x - 17 = 2x - 1 (equal sides)

  • Solve for x

4x - 2x = 17 - 1

2x = 16

x = 8

(3y+5) + (6y -13) = 180

  • Solve for y

9y - 8 = 180

9y = 180 + 8

9y = 188

y = 20.9

Therefore, applying the properties of a parallelogram, the values of x and y are: x = 8; y = 20.9
