Answer:
r = i + j + (-2/3)(3i - j)
Step-by-step explanation:
Vector Equation of a line - r = a + kb ; where r is the resultant vector of adding vector a and vector b and k is a constant
if a = i + j ; b = t(3i - j) and r = -i +s(j)
for this to be true all the vector components must be equal
summing i 's
i + 3ti = -i; then t = -2/3
j - tj = sj; then s = 1-t; substitue t; s=1+2/3 = 5/3
so r = i + j + (-2/3)(3i - j) which will symplify to -i + 5/3j

Answer:
b) 5u.
Step-by-step explanation:
El triangulo es 45-45-90, entonces los dos lados son iguales. Si un lado es 8u, el otro lado tambien es 8u.
Entonces, 8u + x = 13u.
x = 13u - 8u
x = 5u

A triangle is rotated around N to give the primed version.
A. Same shape and size -- TRUE. Rotation doesn't change shape or size.
B. Corresponding points are equidistant to N. That's TRUE, each point is rotated around N to get its corresponding point, which will be the same distance from N.
C. DN=D'N. TRUE, just an example of corresponding points.
D. Corresponding side lengths unequal, FALSE. Rotation doesn't change lengths.
The word mono in Latin means one. Since a monarchy has only one leader, it is logical to say that a monomial has only one term.
