Answer:

x = 7

Step-by-step explanation:

Rearrange the equation to make x the subject.

Original:

7x + 3 = 52

subtract 3 from both sides

7x = 52 -3

7x = 49

Divide both sides by 7

x = 49/7

x = 7

Write the standard equation of the ellipse with center at the origin, and vertices at (-4,0), (4,0), (0, -3), and (0,3).
levacccp [35]

9514 1404 393

Answer:

  (a)  x^2/16 +y^2/9 = 1

Step-by-step explanation:

The form for the equation of an ellipse centered at the origin is ...

  (x/(semi-x-axis))^2 +(y/(semi-y-axis))^2 = 1

The vertex values tell you the semi-x-axis is 4 units, and the semi-y-axis is 3 units. Then you have ...

  (x/4)^2 +(y/3)^2 = 1

  x^2/16 +y^2/9 = 1

__

In case you don't remember that form, you can try any of the points in the equations. The equation that works will quickly become apparent.

Solve by completing the square. w2 − 8w − 39 = 0 Write your answers as integers, proper or improper fractions in simplest form,
adell [148]

Answer:

4+√55= 11.42

4-√55= -3.42

Step-by-step explanation:

  • w² − 8w − 39 = 0
  • w²- 2*4w + 16- 55=0
  • (w-4)²=55
  • w-4=√55 ⇒ w= 4+√55= 11.42
  • w-4=- √55 ⇒ w= 4-√55= -3.42
