4 and 2
Step-by-step explanation:
a positive times a negative makes a negative
The value of x when y = -14 is 7
Step-by-step explanation:
Direct variation is a relationship between two variables that can
be expressed by an equation in which one variable is equal to a
constant times the other
If y varies directly with x, then
- y ∝ x
- y = k x, is the equation of variation where k is the constant of variation
∵ y varies directly with x
∴ y ∝ x
∴ y = k x
To find k substitute x and y by their initial values
∵ y = 16 and x = -8
- Substitute y by 16 and x by -8 in the equation above
∴ 16 = k(-8)
- Divide both sides by -8
∴ -2 = k
∴ The value of k is -2
- Substitute the value of k in the equation above
∴ y = -2 x ⇒ equation of variation
∵ y = -14
- To find x substitute y by -14 in the equation of variation
∵ -14 = -2 x
- Divide both sides by -2
∴ 7 = x
∴ The value of x is 7
The value of x when y = -14 is 7

Answer:
unpaid balance is $156439.86
Step-by-step explanation:
present value= $190000
rate = 3% monthly = 3/12 = 0.25 % = 0.0025
time = 25 year = 25 × 12 300
to find out
the unpaid balance
solution
first we calculate monthly payment
payment = principal ( 1- (1+r)^(-t) /r )
and we put all value here
190000 = principal ( 1- (1+0.0025)^(-300) / 0.0025 )
principal = 190000 / ( 1- (1+0.0025)^(-300) / 0.0025 )
principal = 901
so after 6 year unpaid is
present value = principal ( 1- (1+r)^(-t) /r )
put here principal 901 and rate 0.0025 and time 300 - (year )
time = 300 - (6*12) = 300 - 96 = 228
payment = 901 ( 1- (1+0.0025)^(-228) / 0.0025 )
payment = 901 ( 713.63)
so unpaid balance is $156439.86
