All right sure. Well, first subtract the like terms. $r +3 - 6 = 2

r -3 = 2$
Then, just solve like a regular equation. Add 3 to the other side. Then, r = 5

Given the triangles are similar, calculate the value of y to the nearest tenth.

RoseWind [281]

y=4.5

This is because the ratio between the two triangles is 1:2 so the side lengths of the first triangle is half the corresponding side length of the second triangle.

If the null space of A4×5 is exactly a two-dimensional plane, answer the following:

Hatshy [7]

Answer:

A is a 4 x 5 matrix => A: U -> V, dim U = 5, dim V = 4

Null space is exactly two dimensional plane

dim null (A) = 2

II.

Rank A = dim U - dim Null A = 5 - 2 = 3

III.

Number of linearly Independent columns of A is the rank of A = 3

IV.

Yes, The system Ax = b has no solution sometimes as range of A \neq V

Yes,Sometimes Ax = b has a unique solution

VI.

Yes, sometimes Ax = b has infinitely many solutions

What is the term a8 of the sequence {an} if an equalsa) 2n−1?b) 7?c) 1 + (−1)n?d) −(−2)n?

Degger [83]

The correct question in the attached figure

case A) an=2^(n-1)
for n=8
a8=2^(8-1)-----> a8=2^7----> a8=128

the answer case A) is
a8=128

case B) an=7
then for n=8
a8=7

the answer case B) is
a8=7

case C) an=1+(-1)^n
for n=8
a8=1+(-1)^8----> a8=1+1----> a8=2

the answer case C) is
a8=2

case D)an=-(-2)^n
for n=8
a8=-(-2)^8----> a8=-256

the answer case D) is
a8=-256
