Answer:
s = 6 1/2
Step-by-step explanation:
Answer:
y=2x+7
y=4x+7
y=5x
Step-by-step explanation:
substitute the numbers for the variables in the form y=mx+b
Step-by-step explanation:
solving functions separately.
1st: from given data taxi charges $1.00 for the first mile.so it is first rule of function.

2nd: the company charge $0.20 per tenth of a mile.so 2nd rule of the function will be

simplifying


, 
piece wise function is f(x)={2 , 0<x<1
{x , 1<x<2
the graph of the function is given below
Answer:
P=163,487,500
Step-by-step explanation: P=Ae^(kt)
151000000=145000000*e^(k5)
151000000/14500000=e^(k5)
1.04137931=e^(k5)
Ln 1.04=Ln e^(k5)
0.04=k5
k= 0.008
P=145,000,000*e^(.008*15)
P=145,000,000*e^0.12
e=2.71828
P=145,000,000*1.12749685
p=163,487,500
9514 1404 393
Answer:
(1) -5 and -3
Step-by-step explanation:
Descarte's rule of signs tells you the lack of sign changes among the coefficients means there are <em>no positive real roots</em>. That eliminates all answer choices except the first one.

If you want to go to the trouble, you can factor the equation:
y = (x +3)(x +5)
These factors are zero when x = -5 and x = -3.
