Answer:
Step-by-step explanation:
P=2(L+W), we are given a side of 20 and a side of b
P=2(20+b)
P=40+2b
A) P(6)=40+12=52ft TRUE
B) P(8)=40+16=56ft TRUE
C) P(10)=40+20=60ft FALSE
D) P(12)=40+24=64ft FALSE
E) P(11)=40+22=62ft FALSE
So only A and B are true
1. Add a positive integer by moving to the right on the number line.
2. Add a negative integer by moving to the left on the number line.
3. Subtract an integer by adding its opposite.
Answer:
(-5, -8)
Step-by-step explanation:
<span><span>PART A) the initial value of the function is 150 at 0 weeks, that means that there are still 150 songs to be downloaded at the beginning.
</span> The rate of change is -30 songs each week, that is because the amount of songs left to be downloaded decrease by 30 each week.</span>
<span><span>PART B:
</span><span> lets use 2 points of the graph p1(0, 150), p2(1, 120)
calculate the slope:
m = (y2- y1)/(x2 - x1) = (120 - 150)/(1 - 0)
m = -30
and now use line equation in form point-slope:
y - y1 = m(x - x1)
y - 150 = -30(x - 0)
y = -30x + 150</span></span>
5 x (10^2) =
5 x 100 = 500
I guess you mean:
4,5 x (10^2) =
4,5 x 100 =
450
Which acctually is a valid answer.
