Answer:
C
Step-by-step explanation:
A function is when the x value has ITS OWN Y VALUE, so the x value can't have more than one y value.
Can't be A, because 6 and 13 both have 10
Can't be B, because there are two x - values (6 and 6)
It can only be C, because each x-value has a different y-value
Answer:
y=19.2. because x=8 when x multiply by 1.6, so y should multiply by 1.6 to get 19.2
Step-by-step explanation:
Answer:
5.5
Step-by-step explanation:
Solve first to find y and -9+9 =0
-9x+4y=-17
9x-6y=3
2y= -14
Y= -14/2
Y=-7
Substitute your y answer into first equation solve to find x .
-9x+4(-7)= -17
-9x-28= -17
-9x= -17+28
-9x= 11
X= 11/-9
X= -1.2222 or -1 and 2/9
So answer is (-1.2222, -7)
