Answer:
x = 4
y = 6
Step-by-step explanation:
3x + 4y = 36
3x + 4(-1/2x + 8) = 36
3x - 2x + 32 = 36
x + 32 = 36
x + 32 - 32 = 36 - 32
x = 4
y = -1/2x + 8
y = -1/2(4) + 8
y = -2 + 8
y = 6
Answer:
Total number number of cars which do not have defects = 539
and 21 are defected out of 560 i.e. 560 - 539 = 21
Step-by-step explanation:
Total cars checked by Car factory = 320
Number of defected cars = 12
The number of cars which do not have defects = 320 - 12 = 308
Total Number of cars = 560
So the equation becomes
![\left[560\:\times \:308\right]\:\div \:320](https://tex.z-dn.net/?f=%5Cleft%5B560%5C%3A%5Ctimes%20%5C%3A308%5Cright%5D%5C%3A%5Cdiv%20%5C%3A320)
⇒ 

⇒ 

⇒ 
Therefore, total number number of cars which do not have defects = 539
and 21 are defected out of 560 i.e. 560 - 539 = 21
Answer:
C. The function has a range that is all real numbers.
Step-by-step explanation:
Y has restraints- it doesn't go below 0
therefore it isn't all real numbers. it's more like y≥0
