The coordinates of the midpoint of two points A and B are the averages of the corresponding coordinates of A and B.
So if one point is (a, b) and another point is (c, d), the point exactly between them has coordinates ((a+b)/2, (c+d)/2).
In this example, the points
A(-3a, b)
B(3a, b)
have midpoint
F((-3a+3a)/2, (b+b)/2) = F(0, 2b/2) = F(0, b)
factor the exspresion 8y^2-22y-21
what are you asking help with. Also, i can barely see the image.
2 burgers for $7.79
1 bowl of soup for $4.99
4 drinks for $1.39
They paid 6% tax. They then paid a tip that was about twice the amount of the tax they paid. Which is the closest estimate of the total amount Ethan and his friends paid for their food, drink, tax and tip?
A) $50
B) $35
C) $35
D) $60
6.29 * 2 = 12.58
7.79 * 2 = 15.58
4.99
1.39 * 4 = 5.56
12.58 + 15.58 + 4.99 + 5.56 = 38.71 <-- total without tax/tip
38.71 * .06 = 2.32 <-- tax
2.32 * 2 = 4.64 <-- tip
38.71 + 2.32 + 4.64 = 45.67 <-- total cost
The closet to the total cost would be option A) $50
