OPINION

The appellant challenges the sufficiency of the evidence to *165 support the jury verdict finding her guilty of unlawful use of a credit card, a violation of NRS 205.500.

Since the appellant has cited no authorities in support of her position, this court is not required to consider the assignment of error. Howarth v. El Sobrante Mining Corp., 87 Nev. 492, 489 P.2d 89 (1971); Carson v. Sheriff, 87 Nev. 357, 487 P.2d 334 (1971); Smithart v. State, 86 Nev. 925, 478 P.2d 576 (1970). We have, however, reviewed the entire record and found therein substantial evidence to prove each and every element of the crime with which she was charged. Marshall v. State, 87 Nev. 536, 490 P.2d 1056 (1971); Collins v. State, 87 Nev. 436, 488 P.2d 544 (1971). This independent review of the record which we have conducted clearly establishes that the appellant’s claim of error is frivolous. Gay v. State, 87 Nev. 540, 490 P.2d 666 (1971); Sanchez v. State, 85 Nev. 95, 450 P.2d 793 (1969).

Affirmed.
