The sum of two numbers is 20 and their difference is 12.

4 and 16

Step-by-step explanation:

First, let's find first term using sum formula:

We know that d or common difference is 12 and only sum of two terms so n = 2.

Since sum of two numbers equal 20.

From above, subtract both sides by 12, solving for a1.

Therefore our first number is 4.

Finding next number, create an equation:-

Another number is 16

So 4 and 16 has 12 as difference because 4+12=16 and 16-12 = 4

(x) - (y) = (1 + 4i)

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
