John's income increased by 4%. if his income rose by $850, find his previous amount

$21250

Step-by-step explanation:

x- previous amount

4% of x = $850

0.04x=$850

x= $850/0.04

x=$21250

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

see attached

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
