B. Multiply the top equation by 3
-2y will turn into -6y and the y's will cancel out
Kaia found a common dividend (if thats the right word), a common factor that both could be divided by, and then did the distributive property backwards pretty much, taking out that common factor from each. You can't use it on that last one because eleven is a prime number (unable to be divided by anything other than one and itself), so the two numbers won't have a common dividor number thingy.
Answer:
The answer is 2 and (-9)
Step-by-step explanation:
x² + 7x – 18 = 0
x² + 9x – 2x – 18 = 0
x(x + 9) – 2(x + 9) = 0
(x – 2) (x + 9) = 0
x = (2, -9)
Thus, The zeroes of the polynomial is 2 and (-9).
Answer:
$9.95
Step-by-step explanation:
total cost for 3=$29.85
cost for one = $29.85÷3
answer = $9.95
Answer:
Given differential equation,



Taking integration both sides,

Put 7 - 5y = u ⇒ -5 dy = du ⇒ dy = -du/5,



Here, x = 0, y = 0

Hence, from equation (1),
