Answer:
d) 
Go to station 10
Step-by-step explanation:

Expand:


Subtract 41 from both sides:


Divide both sides by -1:


Answer:
f(x) = (X^3 +6) + 4
Step-by-step explanation:
to move left add +6 from <u>inside</u> the parenthesis
to move up add +4 <u>outside</u> of parenthesis
<em>*since there were no parenthesis you add them*</em>
The value of x satisfies both -9x + 4y = 8 and -3x - y = 4 given the same value of y is
Step-by-step explanation:
The system of equations has two equations:
Let us solve the system of equations to find the value of x and substitute it in the two equations to check if it gives the same value of y in the two equations
∵ -9x + 4y = 8 ⇒ (1)
∵ -3x - y = 4 ⇒ (2)
- Multiply equation (2) by 4 to make the coefficients of y in the
two equations have same value and different signs
∴ -12x - 4y = 16 ⇒ (3)
- Add equations (1) and (3) to eliminate y
∴ -21x = 24
- Divide both sides by -21
∴ x =
Let us substitute this value of x in equations (1) and (2) to find y
∵ -9(
) + 4y = 8
∴
+ 4y = 8
- Subtract
from both sides
∴ 4y =
- Divide both sides by 4
∴ y =
∵ -3(
) - y = 4
∴
- y = 4
- Subtract
from both sides
∴ - y =
- Divide both sides by -1
∴ y =
The value of x satisfies both -9x + 4y = 8 and -3x - y = 4 given the same value of y is

2 + 3w < -1 < 3w + 5 |subtract 3w from all sides
2 < -1 - 3w < 5 |add 1 to all sides
3 < -3w < 6 |change the signs
-3 > 3w > -6 |divide both sides by 3
-1 > w > -2 → -2 < w < -1 → w ∈ (-2, -1)
