Answer:
-5
Step-by-step explanation:
the slope is the variable in front of the x
Answer:
This equation has one solution
Step-by-step explanation:
Number of solution depends on the involved variables so here in this equation only one variable involve so one solution exist.
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:
D, <VMY cannot be a right angle, its an obtuse angle (more specifically, ab a 120 degree angle)
10.99x = 3.99x + 280
7x = 280
x = 40
