A. (−3, 3)
<span>3x – 4y = 21
</span>3(-3) - 4(3) = 21
-21 = 21 >>>>> not equal
B. (−1, −6)
<span>3(-1) - 4(-6) = 21
</span>21 = 21 >>>>>>>>>>Equal
C. (7, 0)
<span>3(7) - 4(0) = 21
</span>21 = 21>>>>>>>>>>equal
D. (11, 3)
<span>3(11) - 4(3) = 21
</span>21 = 21 >>>>>>>>>equal
D. Becaus it is the only one that mentions the characters of a triangle
150+3p
p=30
150+3(30)
150+90
240
When p=30 in 150+3p, the final value is 240.
18 / 2 = 9 || 9 x 3 = 27. Therefore, 27 students are registered in Bob’s class.
