Answer:
x = - 23
Step-by-step explanation:
Given
- x - 7 = 16 ( Isolate - x by adding 7 to both sides )
- x = 23 ( multiply both sides by - 1 )
x = - 23
The range of a log is all real numbers, only the domain is limited. Therefore the answer is +infinity to -infinity.
Answer:
y=-3.571
Step-by-step explanation:
To get rid of the x's make the other x cancel out the other.
5x-y=25+(-5(x+4y=-10)=-21y=75= -3.571
Answer: q = -13
Step-by-step explanation:
(q+5)/4 = -2 first you multiply 4 to remove denominators
(q+5) = -8 then subtract 5
q = -13
Answer 1
The formula of the future value of annuity ordinary is
Fv=pmt [(1+r)^(n)-1)÷r]
Solve the formula for n
Fv/pmt=(1+r)^(n)-1)÷r
cross multiplication
(Fv/pmt)×r=(1+r)^(n)-1
(Fv/pmt)×r+1=(1+r)^(n)
take the log for both sides
Log ((Fv/pmt)×r+1)=n×log (1+r)
Divide each side by log (1+r)
N=[Log ((Fv/pmt)×r+1)]÷log (1+r)
Now solve to find n
N=log((10,000÷800)×0.03+1)
÷log(1+0.03)=10.77years round your answer to get 11 years
Answer 2
PMT=81,000÷(((1+0.075÷12)^(12
×19)−1)÷(0.075÷12))
=161.25
Answer 3
PMT=87,000÷(((1+0.054÷12)^(12
×8)−1)÷(0.054÷12))
=726.56
