The answer is A) -5 (if you get the app math papa you can plug in the equation and plug in the values to get the answer.)
Answer:
x = -2
y = 6
Step-by-step explanation:
y= -3x
x + y =4
Substitute y = -3x from the first equation into the second equation
x + (-3x) = 4
Combine like terms
-2x = 4
Divide by -2
-2x/-2 = 4/-2
x = -2
Now find y
y = -3x
y = -3(-2)
y = 6
For t=0

</span>F1 = P*(1 +(r/m))^n
i=r/m
n=m*t---------- >1*6=6
we have
P1=1870
r=8%
m=1
t=6 years
F1 = 1870*(1 +(0.08/1))^6------------------ >2967.45 dollars
for t=2
Allan borrows--------------------------- > 1240 dollars
for t=6 years
F2 = P2*(1 +(r/m))^n
i=r/m
n=m*t---------- >1*4=4
we have
P2=1240
r=8%
m=1
t=4 years------------> (6-2)=4 years
F2 = 1240*(1 +(0.08/1))^4------------------ >1687 dollars
F1+F2=2967.45+1687=4654.45 dollars
the answer is 4654.45 dollars
A) true
b) true
c) true
d) false
e) true
