Giselle pays $190 in advance on her account at the athletic club. each time she uses the club, $10 is deducted from the account. model the situation with a linear function. a. b = 190 10x b. b = 180 10x c. b = 180 – 10x d. b = 190 – 10x

This is so harddd! solve. 1 + 1 = solve 4 + 4 = solve 3 x 3

This is different from the first one can someone me

Angle xyz is formed by segments xy and yz on the coordinate grid below: a coordinate plane is shown. angle xyz has endpoints at 3 comma negative 1 and 6 negative 2 and 3 comma negative 3 and measures 36.87 degrees. angle xyz is rotated 270 degrees counterclockwise about the origin to form angle x′y′z′. which statement shows the measure of angle x′y′z′?
