Use Gauss–Jordan reduction to solve each of the following systems. (a) x1 + x2 =−1 4x1 −3x2 = 3 (b) x1 +3x2 + x3 + x4 = 3 2x1 −2x2 + x3 +2x4 = 8 3x1 + x2 +2x3 − x4 =−1 (c) x1 +x2 +x3 =0 x1 −x2 −x3 =0 (d) x1 + x2 +x3 + x4 =0 2x1 + x2 −x3 +3x4 =0 x1 −2x2 +x3 + x4 =0

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.

okay..i will pick 8!
