Answer:

See attached picture

Step-by-step explanation:

To graph an absolute value, find the vertex from $f(x) = a|x-h|+k$ where (h,-k) is the vertex. Here (h,-k) is (-3, -2). Then test two points around it like x=-5 and -1.

$f(x) = -0.5|-5+3|-2 = -0.5(2) -2 = -1-2 = -3$

Plot (-5,-3).

$f(x) = -0.5|-1+3|-2 = -0.5(2) -2 = -1-2 = -3$

Plot (-1,-3).

Connect in V shape.

Find the value of n for which the vectors a⃗ =(3,2)a→=(3,2) and b⃗ =(9,n)b→=(9,n) are collinear.

Makovka662 [10]

Answer:

For n=6, the given vectors will be collinear.

Step-by-step explanation:

Collinear vectors are the vectors which lie on the same line or parallel lines. In order to find if two vectors are collinear, their ratio is found. If the ratio is same for all unit vectors then the vectors are collinear.

Given

$a = (a_1, a_2) = (3,2)\\b = (b_1, b_2) = (9,n)$
