Answer:
The easiest way to do this is to reflect Figure I over the Y axis. Then move it up 3 and left 2.
Ok so the average is 50
average of x number of things is
(add value of all things)/x=average
4 test scores needed
so divide by 4
3 test scores ar known
average is 50
x= missing score
(43+48+42+x)/4=50
times 4 both sides
133+x=200
minus 133 both sides
x=67
a score of 67 is needed
1. (x, y) = (7, -12)
2. x = 1, x = 2 are both solutions
Answer:
C
Step-by-step explanation:
3 1/2 x 2 = 7
