Here, 0.625x - y = -9.625
y = 0.625x + 9.625
Substitute the value of y in 2nd equation,
-65x - (0.625x + 9.625) = -5
-65x - 0.625x -9.625 = -5
-65.625x = 9.625 - 5
x = -4.625/65.625
x = -0.070
Now, substitute it in first equation,
-65(-0.070) - y = -5
4.58 + 5 = y
y = 9.58
In short, Your Answer would be: (-0.070, 9.58)
Hope this helps!
Answer:
6 hours
Step-by-step explanation:
6 inches burns at rate .8 inches in 1 hour
to be 1.2 inches has to burn 6 -1.2 = 4.8 inches of the candle
4.8 inches / .8 inches in 1 hour = 6 hours
f^-1(x) = sq.rt 5(x - 10)/5, sq.rt 5(x - 10)/5 is the inverse of y = 5x^2 +10
Step-by-step explanation:
interchanging the variables
x = 5y^2 + 10
5y^2 +10 = x
5y^2 = x - 10
dividing by 5
5y^2/5 = x/5 + -10/5
y^2 = x/5 + - 10/5
y^2 = x/5 - 2
y = 5 (x-10) 0/5 (sq.rt)
g(5x^2 + 10) = 5x/5
g(5x^2 + 10) = x
f^-1(x) = sq.rt 5(x - 10)/5, sq.rt 5(x - 10)/5 is the inverse of y = 5x^2 +10
