Answer:
B is (7,3)
Step-by-step explanation:
Solve for the x-coordinate:
(3+x)/2=5
3+x=10
x=7
Solve for the y-coordinate:
(-8+y)/2=-2.5
-8+y=-5
y=3
So the coordinates of B are (7,3)
Answer:
<h2>y = 6x + 9</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:

m - slope
b - y-intercept → (0, b).
Parallel lines have the same slope.
Therefore if <em>k</em>: y = 6x + 7 → m = 6, and <em>l</em>: y = mx +b,
then <em>l</em> is parallel to <em>k</em> if m = 6.
We have the equation: y = 6x + b.
The line <em>l</em> passes through (0, 9). Therefore b = 9.
Finally we have:
<em>y = 6x + 9</em>
I think this is right maybe
Answer:
Step-by-step explanation:
- The concept of demand is applied, demand may be elastic, inelastic and unitary as the detailed steps and calculations is as shown in the attached file.
- For elastic demand, P > 1
- For inelastic demand, P < 1
- For unitary, P = 1
The standard deviation is the square root of the variance.
