Answer:
∠D = ∠E = 46°
Step-by-step explanation:
∠D and ∠E are interior opposite angles.
∠D = ∠E
2(x + 8) = 3x + 1
2x + 16 = 3x + 1
x = 15°
∠D = 2(15 + 8) = 2 × 23 = 46°
∠E = 3× 15+ 1 = 45 + 1 = 46°
Answer:
Yes, because for each value of x there is only one y.
A and B are equal to 27^-1
Always, never. Since you are multiplying the same number that you are dividing 1 by, they would essentially cancel out and leave you with 1. If a and b are both negative, then because a negative multiplied by another negative is always positive, it would never be equal to -1
