– 4.x + y = -11
by
combining the equations.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3

the answer is  

a.

4,624π mm2

step-by-step explanation:

y=sec x is the correct answer
