Answer:
a) -3
b) 117
c) 100
Step-by-step explanation:
(a) 2(1)²-5(1)
1²= 1
2×1= 2
2-5= -3
(b) 2(9)²-5(9)
9²= 81
81×2= 162
162-45= 117
(c) 2(4)²-5(4) +2(8)²-5(4)
4²=16
16×2= 32
32-20= 12
8²=64
64×2= 128
128-40= 88
88+12= 100
hope it helps!
Answer:
D : { -3, 3, 12}
Step-by-step explanation:
I would suggest substituting the range for the function and solving for x like so.
i.e -6 = 1x-3, -6 + 3 = 1x -3 + 3, -3 = x, <u>x = </u><u>-</u><u>3</u><u>.</u>
0 = 1x - 3, 0 + 3 = 1x - 3 + 3, 3 = x, <u>x = 3</u><u>.</u>
9 = 1x - 3, 9 + 3 = 1x -3 + 3, 12 = x, <u>x = 12</u>
1.89 times 2 is $3.78 which is more than 3.69, so the answer is b.
