One number is 22 more than another. Their product is – 121.Step 1 of 2: Set up an equation to solve the given word problem. Let x be the smaller number. Answer# KeypadKeyboard ShortcutsO x + x + 22 = - 121O x(22x) = - 121O x(x + 22)- 121O x(x – 22)- 121

Let it be:

• x: The smaller number.

• x + 22: The larger number.

The product of both numbers is:

Since the product of both numbers is -121, we can write:

The word 'is' is represented by the symbol =.

Therefore, the equation to solve the given word problem is:

To find the numbers, we solve the previous equation.

Now, we can factor the expression on the left side using the perfect square trinomial rule.

Then, we have:

Finally, we find the another number.

Therefore, the numbers are -11 and 11.

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

1332.

this is because to get from 333 to 999 you multiply by 3, and you should do the same to the number of hours.

therefore you would do 444*3=1332
