Answer:
(2, 4)
Step-by-step explanation:
Midpoint Formula: 
Simply plug in your coordinates into the formula:
x = (5 - 1)/ 2 = 4/2 = 2
y = (5 + 3)/2 = 8/2 = 4
Answer: 8g + 1
Step-by-step explanation:
(5g + 4) + 3(g - 1)
5g + 4 + 3g - 3
Bring like terms together
5g + 3g + 4 - 3
Combine like terms
8g + 1
Answer:
-13
Step-by-step explanation:
2x²+26x+156=0
x²+13x+78=0
x²+13x=-78
x²+13x+169/4=-143/4
(x+13/2)²=-143/4
x+13/2=(i√143)/2 or x+13/2=-(i√143)/2
x=(i√143)/2-13/2 or x=-(i√143)/2-13/2
(i√143)/2-13/2+(-(i√143)/2)-13/2=(i√143-13-i√143-13)/2=-26/2=-13
Answer:
both statements are fine
Step-by-step explanation:
To find the price of a product after decreasing it, they can be done in the two ways that the statement tells us,
First, calculate that% that was decreased and then subtract it from the original price or simply multiply that original price by the percentage in which the new price would remain.
For example:
let "x" be the original price
in the first case it would be:
0.2 * x and then subtract from x, i.e .:
x - 0.2 * x
in the second case it is:
1 - 0.2 = 0.8
that is, the new price would be 0.8 * x
