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
Yes, because you can multiply $3 by 3 to get $9 and 6 muffins by 3 to get 9 muffins.
Answer:
A
Step-by-step explanation:
Take a look at the graph starting from the left. You’ll see that on the horizontal line, the graph starts at -4 then starts to go downward until it gets to -2 and it starts going up after that so your first interval is (-4, -2). The line increases from -2 to 2 and then it starts sliding downward again from 2 to 4 so your second decreasing interval is (2, 4).
The answer is 8/7. 6/7 divided by 3/4 = 6/7 x 4/3. 6/7 x 4/3 = 24/21 = 8/7
