Answer:
x = 108 because of supplementary angles
Step-by-step explanation:
Solving for x:
Since x and 72 are supplemenatry angles, they'll equal to 180, so:
x + 72 = 180
x = 180 - 72
x = 108
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:

Step-by-step explanation:
inconsistent
Option c: 
is the equation of the line
Explanation:
The equation of line EF is given by 
To determine the equation of line in slope intercept form is given by 
where m is the slope.
From the above equation, the slope of the equation is 
Let us substitute the slope in the formula
Thus, the new equation is
Also, it contains the point (0,-2)
Substituting the point in the equation , we get,
Thus, substituting the value of c in the equation , we have,
Thus, the equation of line parallel to the line EF in slope intercept form is
Hence, Option c is the correct answer.
we know that
1) the product of 
and is equal to
2) Double the number 
is equal to
so
3) the product of and added to Double the number is equal to
therefore
the answer is
