On a line segment B is between AC and C is between B and D using the segment addition postulate if AB=7 AC=15 AD=32 what does BC BD and CD equal

Answers

Answer:

BC = 8

BD = 24

CD = 17

Step-by-step explanation:

First i found that I know AB is 7 and AC is 15 so i realize AB is part of AC so I subtract AB from AC for the difference and got the rest using the same logic

If you dont mind a thx 5 star and brainliest is greatly appreciated trying to hit next level and need 5 more brainliest
AB+AC=BC
7+15=BC
BC=22

AB+AD=BD
7+32=BD
BD=39

AC+AD=CD
15+32=CD
CD=47

Consider two linear transformations y = T(x) and z = L(y), where T goes from R^m to R^p and L goes from R^p to R^n. Is the transformationz = L(T(x)) linear as well ? [The transformation z = L(T(x)) is called the composite of T and L.]

Answers

Yes.

Proof: Consider x, y in R^m. Then since T is linear, we have:

T(a*x + b*y) = a*T(x) + b*T(y)

But since L is linear, we have:

L(a*T(x) + b*T(y)) = a*L(T(x)) + b*L(T(y))

So:

L(T(a*x + b*y)) = a*L(T(x)) + b*L(T(y))

and the composition is linear.

Angela bought gifts for her friends, and each gift costs 10$. Let y represent the total cost and x represent the number of gifts. Write an equation to represent the proportional relationship between the total cost and the number of the gifts she bought.

Answers

Answer:

Step-by-step explanation:

If Angela bought gift for her friend and each gift costs 10$. This means that the more the number of her friends, the more the money she will pay and vice versa. This is known as a direct relationship.

Let y represent the total cost and

x represent the number of gifts

According to direct variation]

y ∝ x

y = kx

k is the constant of proportionality

If each gift item cost $10, x gift will cost 10x. The constant of proportionality in this case will be 10. Substituting, the equation will become;

y = 10x

Hence the required relationship is y = 10x
