You can’t really know the y value unless you’re told that they’re both directly proportional. if so, then check out the pic
8 will go into 66 , 8.25 times
Answer:
-21
Step-by-step explanation:
3x7=21 and a negative x a positive is always negative
Answer:
z = -166
Step-by-step explanation:
1. Subtract 3 from both sides to get z/2 = -83
2. Multiply 2 by both sides to get z = -166
z = -166
Answer:
x = 
Step-by-step explanation:
Given
-
=
← factor denominator
-
= 
[ x ≠ 0, x ≠ - 1 as these would make the terms undefined ]
Multiply through by x(x + 1)
4x² - 5(x + 1) = 4
4x² - 5x - 4 = 4 ( subtract 4 from both sides )
4x² - 5x - 9 = 0 ← in standard form
(x + 1)(4x - 9) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
4x - 9 = 0 ⇒ 4x = 9 ⇒ x = 
However, x ≠ - 1 for reason given above, then
solution is x =
