Answer:

Third Choice:

x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}

Step-by-step explanation:

One line has

x + \dfrac{b}{2a} = \pm \dfrac{\sqrt{b^2 - 4ac}}{2a}

The next line's reason is that b/2a was subtracted from both sides.

The missing line is:

x = -\dfrac{b}{2a} \pm \dfrac{\sqrt{b^2 - 4ac}}{2a}

Then it simplifies to

x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}

Use a paragraph, flow chart, or two-column proof to prove the angle congruency. Given: ∠ CXY ≅ ∠ BXY
Llana [10]

Answer:

See explanation

Step-by-step explanation:

Consider triangles CAX and BAX. In these triangles,

  • \overline{AC}\cong \overline{AB} - given
  • \angle CAX\cong \angle BAX - given
  • \overline{AX}\cong \overline{AX} - reflexive property

By SAS postulate, \triangle CAX\cong \triangle BAX

Congruent triangles have conruent corresponding parts. So,

\overline{CX}\cong \overline{BX}

Consider triangles CXY and BXY. In these triangles,

  • \overline{CX}\cong \overline{BX} - proven
  • \angle CXY\cong \angle BXY - given
  • \overline{XY}\cong \overline{XY} - reflexive property

By SAS postulate, \triangle CXY\cong \triangle BXY

Congruent triangles have conruent corresponding parts. So,

\angle XCY\cong \angle XBY

Need some help please
aliina [53]

Answer:

the answer is 12 attendees

Step-by-step explanation:

Let a=the attendees & Let d=the cost

if the budget is $97 and the cost of the gala is represented by the equation d=7a+13, substitute the $97 for d

d=7a+13

97=7a+13

now take subtract 13 from both sides

97-13=7a+13-13

since the 13 cancels out on the right side it'll now read:

84=7a

to get a by itself you now divide 7 from both sides getting a by itself

84/7=7a/7

12=a

so the answer will be 12
