Solve for x x this is part of a larger problem i don t understand why the sign flips when solving

f x+3 inches solve for x

ticket sells for $7 and each adult ticket sells for $10.50. The auditorium can hold no more than 110 people. The drama club must make no less than $840 from ticket sales to cover the show's costs. If x represents the number of student tickets sold and y represents the number of adult tickets sold, write and solve a system of inequalities graphically and determine one possible solution.

ips when solving for x in this small inequality

Use your result in (a) to solve the system: ■(x&+2y&+z&=1@x&y&+2z&=2@x&+y&+2z&=3) Question#2 (5) (modified from #13 p. 102 in your book) Solve the matrix equation for X X[■(1&1&1@1&2&0)]=[■(1&1&1@3&4&2)] Question#3 (5) (modified from #9 p. 102 in your book) Let [■(a&0&b&2@0&a&3&6@0&a&b&c+2)] be the augmented matrix of a linear system. Find for what values of a,b,c the system has: (i) a unique solution (ii) a one-parameter solution (iii) a two-parameter solution iv) no solution Question#4 (7) Write the matrix A=[■(-1&1&-1@1&1&-1@1&-1&2)] as a product of elementary matrices Question#5 (3) Find the determinant by any method: |■(0&-1&0&0&1@1&1&1&3&1@1&2&3&1&2@1&-1&0&3&1@1&-1&1&0&1)| Question#6 (3-2)Given thissystem: ■(x_1&+2x_2&+x_3&=1@x_1&-〖3x〗_2&+0x_3&=2@x_1&+0x_2&+2x_3&=3) a) Use Cramer’s method to solve for x_1 only b) Solve for the other variables by any method.

lve an equation, find the derivative of a function at a point, or calculate the value of a definite integral. However, you must clearly indicate the setup of your question, namely the equation, function, or integral you are using. If you use other built-in features or programs, you must show the mathematical steps necessary to produce your results. Your work must be expressed in standard mathematical notation rather than calculator syntax. Show all of your work, even though the question may not explicitly remind you to do so. Clearly label any functions, graphs, tables, or other objects that you use. Justifications require that you give mathematical reasons, and that you verify the needed conditions under which relevant theorems, properties, definitions, or tests are applied. Your work will be scored on the correctness and completeness of your methods as well as your answers. Answers without supporting work will usually not receive credit. Unless otherwise specified, answers (numeric or algebraic) need not be simplified. If your answer is given as a decimal approximation, it should be correct to three places after the decimal point. Unless otherwise specified, the domain of a function f is assumed to be the set of all real numbers x for which f(x) is a real number. Let f be a twice-differentiable function such that f′(2)=0 . The second derivative of f is given by f′′(x)=x2e2−x−1 for 0≤x≤6 . (a) On what open intervals contained in 0 View More
