All vectors are in Rn. Check the true statements below: A. For any scalar c, u* (cv) = c(u*v).

B. For a square matrix A, vectors in Col A are orthogonal to vectors in Nul A.

C. If vectors v1; :::;vp span a subspace W and if x is orthogonal to each vj for j = 1; :::; p, then x is in W(orthogonal)?.

D. If the distance from u to v is equal to the distance from u to -v, then u and v are orthogonal.

E. v*v =llvll^ 2

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?

He graph of f(x) = |x| is stretched by a factor of 0.3 and translated down 4 units. which statement about the domain and range of each function is correct? the range of the transformed function and the parent function are both all real numbers greater than or equal to 4. the domain of the transformed function is all real numbers and is, therefore, different from that of the parent function. the range of the transformed function is all real numbers greater than or equal to 0 and is, therefore, different from that of the parent function. the domain of the transformed function and the parent function are both all real numbers.
