Answer:
120 min
Step-by-step explanation:
step 1. divide 100% by 2.5 (=40)
step 2. 40 time 3 minutes = 120!
so by the time it gets to 120 minutes it 100% and guaranteed
y = x^2 + 5x -3
y-x =2
Replace y in the second equation with the first one:
x^2 + 5x -3 - x = 2
Simplify by combining like terms:
x^2 + 4x -3 = 2
Subtract 2 from both sides:
x^2 + 4x -5 = 0
Fctor the polynomial:
(x-1) (x+5) = 0
Solve for both X's:
x = 1 and x = -5
Now replace x in the second equation with both value and solve for y:
y -1 =2, y = 3
y - -5 =2, y +5 = 2, y = -3
Now combine the sets of answers:
(1,3) and (-5,-3)
Answer:
120.9
Step-by-step explanation:
I dunno if this is right or wrong but this is what a calculated somehow please tell me if this is wrong or not
100 * 100 = 10,000.
10,000 * 100 = 1,000,000
100^3 = 1,000,000.
