Answer:
w(t-4)=t^2-9t+20
Step-by-step explanation:
w(t)=t^2-t
w(t-4)=(t-4)^2-(t-4)
w(t-4)= t^2-8t+16-t+4
w(t-4)=t^2-9t+20
The amount of money that Davis has in this scenario is; $50
<h3>How to solve algebra word problems?</h3>
Let the amount of money he has be $X.
Now, if he buys 10 notebooks, he will have $10 left. Thus;
X - 10n = 10 -----(1)
If he buys 15 notebooks, he will be $10 short. Thus;
X - 15n = -10 ------(2)
Subtract eq 1 from eq 2 to get;
-5n = -20
n = -20/-5
n = 4
Thus;
X - 10(4) = 10
X = 10 + 40
n = $50

The answer is Debt
Financing helps you manage your money properly and helps you eliminate risks of going into debt
Answer:
option (c)
Step-by-step explanation:
Given,
ABCD is a square.
AC and BD are diagonals
We know that,
Sides of the square make 90 degrees with each other.
And Diagonals bisect the opposite angles of the square.
Now,
Hence, option (c) is correct.
Distance=speed times time
find time
divide both sides by speed
distance/speed=time
distance=60
speeed=40
60/40=6/4=3/2=1.5
answer is 1.5hours
