correct me if im wrong
tnx
Answer:
The second one
Step-by-step explanation:
B c A
Because B has c and a, which is part of A (A={a, b, c})
The rate of change of function 1 (a horizontal line) is zero.
The rate of change (slope) of function 2 is the x-coefficient, 8.
8 is 8 more than 0.
The 4th selection is appropriat:
8
Answer:
I think its 3 1/4
Step-by-step explanation:
9 3/4 ÷ 3 = 3 1/4

To factor quadratic equations of the form ax^2+bx+c=y, you must find two values, j and k, which satisfy two conditions.
jk=ac and j+k=b
The you replace the single linear term bx with jx and kx. Finally then you factor the first pair of terms and the second pair of terms. In this problem...
2k^2-5k-18=0
2k^2+4k-9k-18=0
2k(k+2)-9(k+2)=0
(2k-9)(k+2)=0
so k=-2 and 9/2
k=(-2, 4.5)
