Asystem of equations is shown:
2x + 5y + z = 3
4x + y − z = 5
3x + 2y + 4z = 1
a. represent this system as a linear transformation in three-dimensional space represented by a matrix equation
in the form of ll= b.
b. what assumption needs to be made to solve the equation in part (a) for x.
c. use algebraic methods to solve the system

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

step-by-step explanation:

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
