要正确区分iPhone的官翻机,可以参考以下几个方面: 1. 价格:官方翻新机的价格会比全新机稍低,但不会特别便宜。如果价格过低,有可能是非正规渠道销售的翻新机。 2. 销售渠道:建议选择正规的苹果授权销售商或官方网站购买,以确保购买的是正品官翻机。 3. 包装:官方翻新机的包装应与全新机一致,通常有一个密封的外包装,内部配有完整的配件,如充电器、数据线、耳机等。 4. 外观:官方翻新机外观应该没有明显的磨损、划痕或凹陷。可以细心观察手机背面、边框和屏幕是否有损坏或异样。 5. 系统:确认手机是否已经恢复出厂设置,以确保没有其他用户的个人信息和数据。 此外,如果有条件的话,可以通过官方的验证工具来检查购买的iPhone是否为官方翻新机。

只是他发出来的方式确实不对,所以引起了争议,以后还是更谨慎一些吧!

解方程组x-3y=32x+y=-2?
To solve the system of equations x - 3y = 32 and x + y = -2, we can use the method of substitution or elimination. Method 1: Substitution Step 1: Solve one equation for one variable in terms of the other variable. From the second equation, we have x = -2 - y. Step 2: Substitute the expression for x into the other equation. In the first equation, replace x with -2 - y: (-2 - y) - 3y = 32. Step 3: Simplify and solve for y. -2 - y - 3y = 32 -2 - 4y = 32 -4y = 34 y = -34/4 y = -17/2 Step 4: Substitute the value of y back into one of the original equations to solve for x. Using the second equation: x + (-17/2) = -2 x - 17/2 = -2 x = -2 + 17/2 x = -4/2 + 17/2 x = 13/2 So the solution to the system of equations is x = 13/2 and y = -17/2. Method 2: Elimination Step 1: Multiply the second equation by 3 to make the coefficients of y in both equations equal. Original equations: x - 3y = 32 and x + y = -2. After multiplying the second equation by 3: 3x + 3y = -6. Step 2: Add the two equations together to eliminate the y terms. (x - 3y) + (3x + 3y) = 32 + (-6) 4x = 26 x = 26/4 x = 13/2 Step 3: Substitute the value of x into one of the original equations and solve for y. Using the second equation: (13/2) + y = -2 y = -2 - 13/2 y = -4/2 - 13/2 y = -17/2 So the solution to the system of equations is x = 13/2 and y = -17/2.
