The answer is 157.5
A 5% discount is 0.05 then, you have to multiply 150 times 0.05 after, that you get 157.5.
HOPE THIS HELPS!!!!
Hello from MrBillDoesMath!
Answer:
Choice D.
Discussion:
Substitute x = 9 in the choices
A. when x = 9, x^2 - 6x + 9 = 36
B. when x = 9, x^2 + 16x + 63 = 288
C. when x = 9, x^2 + 14x + 45 = 252
D. when x = 9, x^2 -12x + 27 = 0
Thank you,

Answer:
The COMMON RATIO of the sequence is -2.
Step-by-step explanation:
Here, the given sequence is:
5, -10, 20 ,-40
Here, The first term ( a 1 ) of the sequence is (5)
The second term (a 2) of the sequence is (-10)
Third term of sequence (a 3) is 20
Now, calculating the common ratio (r) of sequence ,we get:

So, here r =(-2)
⇒ The COMMON RATIO of the sequence is -2.
Hence, the given sequence in in GEOMETRIC PROGRESSION.
1) <span>30x4 − 20x3 + 15x2
This is the answer to 1. Don't forget to rearrange the terms in ascending order. That can trip people up.
2) </span><span>x3 + 8x2 + 13
Don't forget to check the terms sign. The subtraction symbol switches them all. </span>
898.55 = 4.55 × 26 + t
t = tips
4.55 × 26 = 118.3
898.55 = 118.3 + t
898.55 - 118.3 = 780.25
780.25 = t
Your answer is D
