Answer:
X * (X +1) = 420
X^2 + X = 420
X^2 + X -420 = 0
X = 20
Step-by-step explanation:
Question:
Point T, the midpoint of segment RS, can be found using the formulas x = (1/2) (6 – 2) + 2 and y = (1/2) (4 – 6) + 6. What are the coordinates of point T?
Answer:

Step-by-step explanation:
Given


Required
Determine the coordinates of T
The coordinates of T can be represented as 
To do this, we simply solve for x and y

Solve 6 - 2

Solve 1/2 * 4



Solve 4 - 6

Solve 1/2 * -2


Hence, the coordinates of T(x,y) is:

88 + 89 + 79 + 77 = 333. 420-333= 87. The minimum score he can get is 87
The first one is 13 points and the 2nd one is 8. I'm pretty sure, hope this helps! :)
Translation of 7 units to the right ⇒ subtract 7 units to the argument ⇒ f(x-7)
Translation of 5 units up ⇒ add 5 units to the function ⇒ f(x) + 5
g(x) = f (x-7) + 5 = (x-7)^2 + 5
The subtraction of 7 units to the argument of the function (this is x) translates the function 7 units to the right.
Adding 5 units to the function f, translates the graph 5 units up.
