Answer:
You count something
Step-by-step explanation:
If you imagine 9 slots that are empty and you fill 3 of them then there is 6 empty slots so -6
square root of 30. Hope this helps
Y = -2 x - 9
3 x - 4(-2 x - 9 ) = -8
3 x + 8 x + 36 = - 8
11 x = - 44, x = - 4
y = 8 - 9 , y = -1
This is a unique solution, the system is independent.
Answer:
18,0
Step-by-step explanation:
By useing desmos, the line has an x intercept of 18 making that the answer.
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
