Find the equation of the straight line passing through the point (0,1) which is perpendicular to the line y= -2x + 2
mylen [45]

Answer:

y = 1/2x + 1

In order to evaluate a slope that is perpendicular to the given equation, you need to find the opposite reciprocal of the original slope. This means you take the original slope, flip the numerator and the denominator, and change the sign in front.

-2 ⇒ 1/2

Next, we need to substitute the information given into the point-slope formula.

The point-slope formula is:

y - y₁ = m(x - x₁)

y - 1 = 1/2(x - 0)

y - 1 = 1/2x

y = 1/2x + 1

Therefore, the line perpendicular to y = -2x + 2 is y = 1/2x + 1.

You shopped online and found you mp3 player for $9.75 less than the store price p. The online price was $64. Write and solve an
katrin [286]

Answer:

  • 64 = p - 9.75
  • p = 73.75

Step-by-step explanation:

A value that is 9.75 less than p can be represented by the expression ...

  p - 9.75

We are told that value is equal to 64, so the equation is ...

  64 = p - 9.75

__

This equation is solved by adding 9.75 to both sides.

  64 +9.75 = p -9.75 +9.75

  73.75 = p

The store price is $73.75.

Is 4y^2 + 9 = -4 a linear equation?
bekas [8.4K]

Answer:

  No.

Step-by-step explanation:

The exponent of y is 2, which is not 1, so the equation is 2nd degree, <em>not linear</em> (1st degree).

Determine the relationships between the following lines: *
Dennis_Churaev [7]

9514 1404 393

Answer:

  the lines are perpendicular

Step-by-step explanation:

You can tell something by looking at the differences of coordinates:

  B-A = (6-2, -11-5) = (4, -16) . . . . . Δy/Δx = -16/4 = -4

  D-C = (-1-3, 9-10) = (-4, -1) . . . . .  Δy/Δx = -1/-4 = 1/4

The product of the slopes of these lines is (-4)(1/4) = -1, so ...

  the lines are perpendicular
