Combining the numbers, we get 3w+12=5
3w=-7
w=-7/3
We have that
the first balance indicates--------> 10 g
the second balance indicates--------> 0 g
the third balance indicates--------> 7.5 g
therefore
the <span>mass of the chick is (10+0+7.5)----> 17.5 g
the answer is
17.5 g</span>
Answer:
f(x) = x^2 + 3x + 2.
Step-by-step explanation:
The zeroes of the quadratic function are -1 and -2 so we can write it as:
f(x) = a(x + 1)(x + 2) where a is some constant.
Now, when x = 1, f(x) = 6 so
6 = a(1+1)(1+2)
6 = a*2*3 = 6a
a = 1.
So the function is f(x) = (x + 1)(x + 2) = x^2 + 3x + 2.
