x-4 ≥12

Step-by-step explanation:

Hi, to answer this question we have to know what an inequality and a variable are:

Inequality: An inequality is a expression that compares two values, showing if one is less than, greater than, or simply not equal to another value.

Variable: is a symbol for a number that is unknown: they usually are letters (x;y).

An inequality that contains at least one variable could be:

x-4 ≥12

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5
