Answer:
x = 9
Step-by-step explanation:
5 9
(x - (—— • x)) - — = 0
10 2
Simplify 1/2
1 9
(x - (— • x)) - — = 0
2 2
x = 9
Answer:
The correct answer is:
Option 2: Yes, because the slopes of lines are negative reciprocals.
Step-by-step explanation:
Given equations of lines are:
Line p: x+2y=1
Line q: y=2x+1
We can determine if two lines are parallel or perpendicular by comparing the slopes of line.
Slope intercept form of line is given by the formula

Equation of line q is already in slope intercept form.
We have to convert the equation of line p in slope-intercept form

Slope of line p = 2
Slope of line q = -1/2
We can see that

The product of slopes of both lines is -1, hence, the lines are perpendicular.
Hence,
The correct answer is:
Option 2: Yes, because the slopes of lines are negative reciprocals.
Answer:
not so sure though but I think thats the answer
1/2a - 7 + 1/2a = 1/3
1/2a + 1/2a = 1/3 + 7
2/2a = (1 + 21)/3
a = 22/3
Answer With Step-by-step explanation:
C: 3
This is because 6 3/5 is a positive number, and 6 3/5 ÷ 2 1/5 = 3
