Answer:

The slope of the line through (-1, 8) and (3, -4) = m = -3

Step-by-step explanation:

Given the points

  • (-1, 8)
  • (3, -4)

Determining the slope between (-1, 8) and (3, -4)

  • (x₁, y₁) = (-1, 8)
  • (x₂, y₂) = (3, -4)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

                 =  [-4 - 8] / [3 - (-1)]

                 = [-12] / [3+1]

                 = -12/4

                 = -3

Thus, the slope of the line through (-1, 8) and (3, -4) = m = -3

Answer:

The answer is -3

Step-by-step explanation:

Slope = Rise/Run = Change  in y/Change in x

Slope = (-4 - 8) / (3 - -1)

= -12/4

= -3

So, the answer is -3

Hope this helps! :)

BCDE is a parallelogram. What is the measure of ∠BEC? Enter your answer in the box. ° A parallelogram B C D E. Side E D is the b
Elenna [48]

Solution:

In Parallelogram B CDE

BC= DE, BC ║DE

CD = BE , CD ║BE

Also, ∠B=∠D and ∠C=∠E →→In a parallelogram opposite sides are equal and parallel, as well as opposite angles are equal.Diagonals Bisect each other.

∠B= 60° , ∠C ED= 40°

CE is a transversal and BC║DE.

∠CED=∠BCE = 40° →→Alternate interior angles

In Δ BCE

∠B + ∠BCE + ∠BEC= 180°→→→Angle sum property of Triangle.

60° + 40° + ∠ B E C= 180°

100° + ∠BEC=180°

∠BEC= 180° -100°

∠BEC= 80°

AABC - ADEF <br><br> Find the value of x
kobusy [5.1K]

Answer:

\boxed{x = 4}

Step-by-step explanation:

If ΔABC ~ ΔDEF

Then their sides must be proportional such that:

=> \frac{x}{3} = \frac{8}{6}

Cross Multiplying

=> x * 6 = 8*3

=> 6x = 24

Dividing both sides by 6

=> x = 4

Please answer this ASAP. The question is down below. Thank you!
Sonja [21]

Answer:

y = .5x^2 -2x -5

Step-by-step explanation:

Well we can start by seeing if the parabola is the same width by comparing it to its parent function ( y = x^2 )

In y = x^2 the 2nd lowest point is just up 1 and right 1 away from the vertex.

This is not true for our parabola.

So we can widen it by to the desidered width by making the x^2 into a .5x^2.

So far we’ve got y = .5x^2

Now the parabola y intercept is at -5.

So we can add a -5 into the equation making it.

y = .5x^2 - 5

Now for the x value.

So we can find the x value by seeing how far away the parabola is from from the y axis.

So the x value is -2x.

So the full equation is y = .5x^2 -2x -5

Look at the image below to compare.
