Answer:
y=61, x=112
Step-by-step explanation:
119+y=180
180-119=y
61=y
131+56+61+x=360
248+x=360
360-248=x
112=x
Answer:
12.8% decrease
Step-by-step explanation:
if you find the unit rate for the sale, which would be 125 cents divided by 3 cans, equals around 43.6 cents per can. 43.6 cents is an x% decrease of 50 cents, and to find x easily i multiplied by 2. 43.6 x 2=87.2, and 50 x 2 = 100. that means that the sale price is 87.2 % of the original price, which is a 12.8% decrease.
Answer:coefficient of x term is 8
Step-by-step explanation:I(2x-5)(x2-3x2+4)
(2x-5)(-2x2+4)
-4x3+8x+10x2-20
coefficient of x is 8
Answer:
-164 ft/second.
Step-by-step explanation:
The instantaneous velocity is given by the derivative;
f(t) = -16t^2 + 220t
V = f'(t) = -32t + 220
So at 12 seconds:
V = -32*12 + 220
= -164 ft/second ( It is negative because it is descending).
