解析 答案:(1)x≤1 (2)y=x+1 4 解析:依题意,题目所给的程序是求函数y=的函数值.因此,当x≤1时,没有执行语句y=x+1;又当x>1时,x+1>2,当x≤1时,2x+1≤3,从而输出的y的值是5时,执行的赋值语句是y=x+1,故输入的x的值为x=5-1=4....
If x≤5 Then y←-x2+1 Else y←2x+9 End If Print y 若使输出的y值为-3,则输入的x值应为 . 相关知识点: 算法与框图 算法初步与框图 伪代码(算法语句) 试题来源: 解析答案:±2或6. 依题意y=-3,当x≤5时,-x2+1=-3,解得x=±2, ...

1+(1−x)=2−x So, the equation becomes:2x2−x=1 Step 4: Cross-MultiplyCross-multiply to eliminate the fraction:2x=2−x Step 5: Solve for xNow, add x to both sides:2x+x=23x=2 Now, divide both sides by 3:x=23 Final AnswerThus, the value of x is:23 --- Show More...
If 6e^{5x} = 23, then what does x equal? f(x)= 7-5x^4 What does __x__ equal What the x is equal to: 9x+7=5 If 9^x = 243, what does x equal? Solve for x: 5/(x - 1) - 7/x = \frac{3}{2x-2} Solve for x. -6/((x - 1)(x - 6)) = 4 - 5/(x - ...
