The first step in solving the given system of equations 3x + 2y = 8
-x + y = -11

by substitution is

Step-by-step explanation:

3x + 2y = 8 (1)

-x + y = -11 (2)

(2) multiply by 3;

3 * (-x + y) =  3 * (-11 )

-3x + 3y = -33 (3)

(1) + (3)

(3x + 2y)  + ( -3x + 3y)   = 8 + (-33)

3x -3x + 2y + 3y = -25

5y = -25

y= -5

value of y substitution in to (2);

-x + y = -11

-x + (-5) = -11

-x = -6

x=6

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

answer: b.36 feet
