Good morning
Answer:
NO
Step-by-step explanation:
Here we just substitute x and y by their values and see if the inequality still true or not
y = 3
6x + 3 = 6(2) + 3 = 15
since 3 < 15 then the inequality y > 6x + 3 is wrong.

2x2-8x (two x squared minus 8 x)
Step-by-step explanation:
e = 20sin(πt/4 - π/2)
= 20[(sinπt/4)(cosπ/2) - (cosπt/4)(sinπ/2)]
Used sin(x - y) = sinxcosy - cosxsiny.
= 20[0 - cosπt/4]
Since cosπ/2 = 0 and sinπ/2 = 1.
= -20cosπt/4.
