X+4=y=-2x-2
x+4=-2x-2
add 2x to both side
3x+4=-2
minus 4 both sides
3x=-6
divide 3
x=-2
sub back
y=x+4
y=-2+4
y=2
(x,y)
(-2,2)
Answer:
a) Job A.
Step-by-step explanation:
Time, t = 2000 hours per year
Job A:
Salary = $13 per hour
Job B:
Salary = $11 per hour
Healfh insurance = $3400 per year
= $3400/2000
= $ 1.7 per hour
B:. Mb = $11 × 2000 = $22000
Health insurance costs 3400$ per year so while we are working our job A we have: so $11.3 × 2000 = $22600. So on job A we earn $600 per year more than on job B.
Answer:
a) Amount saved if the interest is compounded annually is $5832
b) Amount saved if the interest is compounded semi-annually is $5849.5
Step-by-step explanation:
Principal Amount P = 5000
Time t = 10 years
Annual interest i = 8% = 0.08
We need to find amount saved if interest is compounded a) annually b) semi-annually
a) Amount saved if the interest is compounded annually
If interest compounded annually, n= 1
Using Formula:
Putting values:
So, Amount saved if the interest is compounded annually is $5832
b) Amount saved if the interest is compounded semi-annually
If interest compounded semi-annually, n= 2
Using Formula:
Putting values:
So, Amount saved if the interest is compounded semi-annually is $5849.5
