where is the 2x coming from here - Consider the congruence: [ 2x \equiv 14 \pmod{26} ] This congruence has multiple solutions. For instance: [ x = 7 ] [ 2 \cdot 7 = 14 \equiv 14 \pmod{26} ] And: [ x = 20 ] [ 2 \cdot 20 = 40 \equiv 14 \pmod{26} ] Both ( x = 7 ) and ( x = 20 ) satisfy the congruence, showing that there are multiple solutions

4) The mean salary of 5 employees is $35900. The median is $36800. The mode is $38000. If the median paid employee gets a $3200 raise, then ... Hint: It will help to write down what salaries you know of the five and think about how you normally calculate mean,median, and mode. a) What is the new mean? New Mean = $ b) What is the new median? New

ECU, Math 2121, Spring 2020, May 1, I. Patyi, fa. Name: 27. Let x = Q1 be the point of inflection of f(x) = 19x3 + 21x2 + 17x + 15. Let Q2 = 1 if f increases in an interval centered at x = Q1, and Q2 = 0 otherwise. Let 2 210 Th 5 cin2(1000) satisfies.- ( A)OCT (B )

A variable is a symbol used in place of a number that is not known. For example, x+4=8 where x is the variable. To teach this you would show an algebraic expression and ask students if they can figure out the missing number. Then tell them the symbol they are replacing is called a variable. After that, you will do several more examples and have
