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:
19 Cds left.
Step-by-step explanation:
The question said he used 31 Cds, so 50 minus 31 is 19.
90%=0.9
30%=0.3
115.9%=1.159
9%=0.09
7%=0.07
0.452=45.2%
0.006=0.6%
0.002=0.2%
0.05=5%
4.78=478%
