Step-by-step explanation:
y=3x
so
3x=-x+4
3x+x=4
4x=4
x=1
so
y=3(1)
y=3

Step-by-step explanation:
![\sqrt[3]{8} = 2](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8%7D%20%3D%202)
The answer is <span>C.33

3 * (-2)ⁿ⁻¹
n = 1; 3 * (-2)¹⁻¹ = 3 * (-2)⁰ = 3 * 1 = 3
n = 2; 3 * (-2)²⁻¹ = 3 * (-2)¹ = 3 * (-2) = -6
n = 3; 3 * (-2)³⁻¹ = 3 * (-2)² = 3 * 4 = 12
n = 4; 3 * (-2)⁴⁻¹ = 3 * (-2)³ = 3 * (-8) = -24
n = 5; 3 * (-2)⁵⁻¹ = 3 * (-2)⁴ = 3 * 16 = 48
The sum is:
3 + (-6) + 12 + (-24) + 48 = 3 - 6 + 12 - 24 + 48 = 33

Pretend that the line is right below the greater than sign.
To help solve this problem, create a simple equation.
Let x = weekly allowance.
(x/2) + $4 = $11. Subtract 4 from each side
(x/2) = 7. Multiply each side by 2
x = $14.
Joe's weekly allowance is $14
