Answer:
solid...(-3,0)(-4,-1)...shaded below the line
slope = (-1-0) / (-4-(-3) = -1/(-4 + 3) = -1/-1 = 1
y = mx + b
-1 = 1(-4) + b
-1 = -4 + b
-1 + 4 = b
3 = b
this line is : y < = x + 3 <== (thats less then or equal)
====================
solid...(1,1)(2,-1)...shaded below the line
slope = (-1-1) / (2-1) = -2/1 = -2
y = mx + b
1 = -2(1) + b
1 = -2 + b
1 + 2 = b
3 = b
Step-by-step explanation:
Let the number of CD's be x and total cost be y
y=7x-10
*the 7 comes from the price of each individual CD ($7)
*the 10 comes from the discount ($10)
Answer: x=−1 or x=1 or x=−2 or x=3
Step-by-step explanation: Step 1: Factor left side of equation.
(x+1)(x−1)(x+2)(x−3)=0
Step 2: Set factors equal to 0.
x+1=0 or x−1=0 or x+2=0 or x−3=0
x=−1 or x=1 or x=−2 or x=3
<span>Growth rate = (Present - Past)/Past
Plugging in what we know
Growth rate =(5600â’4420)/4420
Thus
Growth rate=.26697
Now we can plug the growth rate into our first formula which gives us
P=5600e^(.26697â‹…2)
Solve for P and we get
P
=
9551.58
however since you can not have .58 of a person we round down to 9551.
So Youngtown will have 9551 citizens in the year 2000</span>
