2. identify if the expressions below are
polynomials or not. (drag and drop)
a. -0.7jk2 + 0.0015jk + 0.25k
b. 2vx + 5x
c. 2y2 + 2z - y
d. -*x2+x-1
e x3 + x² v5 - 2x
f. 2y+ + 5 -

Which equation represents the line that passes through the points and (4, 10) and (2, 7)? y = 3/2x - 11y = 3/2x +4y = - 3/2x + 19y = - 3/2x + 16

Graph the equation by plotting point x=2

International calls require the use of a country code. many country codes a 3-digit numbers. country codes do not begin with a 0 or 1. there are no restrictions on the second and third digits. how many different 3-digit country codes are possible?
