The answer is D. because you use Pythagoreans theory and do 12^2+23^2 which equals 673, then you root it and get 26.
F(x)=3x2-11
f(5)=6-11
5f=-5
5f/5=-5/5
f=-1
Answer:
A.
Step-by-step explanation:
First up, chill a bit xd
So hot dog = x
Drink = y
2 hot dogs = 2x
2 drinks = 2y
2x + 2y = 4.75
3 hot dogs = 3x
1 drink = y
3x + y = 7.75
Its the second one. The inverse is the opposite of the original
<span>if v belongs to V, then we can find scalars a1,a2,...,an, such that
v=a1*v1+a2*v2+...+an*vn,
L1(v)=L1(a1*v1+a2*v2+...+an*vn)
=a1*L1(v1)+a2*L1(v2)+...+an*L1(vn)
=a1*L2(v1)+a2*L2(v2)+...+an*L2(vn)
=L2(a1*v1+a2*v2+...+an*vn)
=L2(v)</span>
