(1.2: Solving linear equations) Consider the following linear system withaandbunknown non-zero constants. x1−3x2+x3=42x1−8x3=−2−6x1+ 6x2+ax3=b(a) For what values ofaandbdoes the system have infinitely many solutions?(b) Given an example ofaandbwhere the system has exactly one solution.(c) Give an example ofaandbfor which the system has no solutions.

there is no

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
