Equations:
Y=-50x+14,040
Y=20x+12,500
Solution X=22, Y=12,950
They will be at the same spot when the graphs intersect and the poi is (22 , 12,940)
So they will meet up at 22, 12,940
2.5 / 18 = 6.4 / x
cross multiply
(2.5)(x) = (18)(6.4)
2.5x = 115.2
x = 115.2 / 2.5
x = 46.08 inches
Answer:
Unicorn A is 300 years old
Unicorn B is 20 years old
Explanation:
15x + x = 320
16x = 320
x = 20
15 * 20 + 20 = 320
So the rule with multiplying exponents of the same base is to add the exponents together. Applying this rule here would look like this:
In short, your simplified expression is going to be -16x^7y^6.
