You would have to add x1 + x2 and divide by 2. do the same with y1 and y2.
(1/2,-1/2)
Answer:
Yes
Step-by-step explanation:
Hi, the expression is correct.
Since she wants to price (p) her used books with a 50% gross profit, to do this she has to multiply the cost of the books (c ) by a percent increase (1 + %/100).
So, for a 50% gross
p = (1 + 50/100) c = (1+ 0.5 )c
p= 1.5c

Answer:
y=-⅓x+7
Step-by-step explanation:
Since the new line we need to make must be parallel to the old one the number changing x must stay the same. this means that that we will still have -⅓ X. Now that we have part of the line formula, we can try to fit it to the point. Because the X is equal to 9, -1/3*9 is -3. To get it to the correct point, we have to add 7, so that our Y is 4. If we combine the two parts of the equation, we get Y=-⅓x+7
Answer:
X = -14
All you have to do is type in 2(x+5)=(x-4) in to a algebra calculator and you will get -14
140>120
70% of 200>3/4*160
