That in algebraic form would be \frac{1}{2}n + 15 = 9

Subtract 15 to both sids and you get
\frac{1}{2}n = -6

Multiply 2 on both sides and you get
n = -12

Can someone please answer?<br><br> Which theorem is it?
tamaranim1 [39]

9514 1404 393

Answer:

  HL

Step-by-step explanation:

The triangles are right triangles, opening the possibility of using the special right-triangle congruence theorems.

The hypotenuses are marked congruent, and one leg is shared. No angles (except the right angle) are marked congruent. With only two sides and one angle, the AAS, SSS, and ASA theorems cannot apply.

The HL theorem can be used to show the triangles are congruent.

Airida [17]

Answer: a

Step-by-step explanation:

\left(\frac{f}{g} \right)(x)=\frac{f(x)}{g(x)}=\frac{\sqrt{x^{2}-1}}{\sqrt{x-1}}}=\sqrt{\frac{x^{2}-1}{x-1}}=\sqrt{\frac{(x-1)(x+1)}{x-1}}=\boxed{\sqrt{x+1}}

Select point B, and drag it. As you drag B, circle AB changes. Verify that you can make circle AB coincide with AC. Return B to
-BARSIC- [3]

Answer:

When AB coincides with AC, the boundary of EAF maps exactly onto the boundary of CAD, implying that EAF dilates into CAD. So, the boundaries of EAF and CAD are similar.

The proportional relationship may be stated in different forms, but should be equivalent to this equation:

radius of Ab/ radius of Ac= length of arc EF/ length of arc CD

Explanations will vary, but should be based on the similarity of EAF and CAD. The proportional relationship follows from the fact that corresponding pairs of lengths in two similar figures have the same ratio.

Step-by-step explanation:

This is the exact answer so make sure you change it up a little.
