-194
F(10)= -(10)^2-9(10)-4=-194
Step-by-step explanation:
if the 2 matrices are inverse, then their product must be the identity matrix
1 0
0 1
so,
m×3 + 2×-7 = 1
7×3 + 3×-7 = 0
m×-2 + 2×m = 0
7×-2 + 3×m = 1
that means we have to solve only
3m - 14 = 1
3m = 15
m = 5
The answer is $4.05 you know where to put the decimal point because money value ends in the hundreth place. hope this helps !
I think its A and D, I'm takeing this 1 right know lol, if you already took it do you remember which were correct?
Whenever two lines intersect, they form two pairs of vertical angles. Vertical angels have a common vertex, but they are never adjacent angles. Fin, vertical angles are always congruent.
