Answer:
Assuming you just want it simplifies, the answer would be m+5
Step-by-step explanation:
4m+5-3m -------> combining like factors
m+5
Answer:
C
Step-by-step explanation:
Tides can be predicted far in advance and with a high degree of accuracy. Tides are forced by the orbital relationships between the Earth, the moon and the Sun. ... The predictability of planetary motion means that we can also reconstruct tides in the past.
QUESTION 1
The given system of equations are:
We equate the two equations to get:
When x=0,
The solution is (0,1)
QUESTION 2
The given equations are:
and
We equate both equations to get:
Group similar terms,
We put x=0 into any of the equations to find y.
The solution is (0,-1).
QUESTION 3
The given equations are:
and
We equate both equations:
Group similar terms:
This is not true.
Hence the system has no solution.
Answer:
$150
Step-by-step explanation:
Simple interest for any principal amount p , rate of interest r and time t is given by
Simple interest = (p*r*t)/100
_________________________________
Given
p =$500
r = 3%
t = 10 years
Therefore SI = $500*3*10/100 = $150.
$150 is earned in 10 years at 3% simple interest on $500.
