Explain the following: · like terms
· unlike terms
· distributive property
· using estimation
· steps to solve an equation
· writing inequalities
· solving inequalities

· like terms-  like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers. The order of the variables does not matter unless there is a power

· unlike terms  -  The terms having the same variable with different exponents or different variable with same exponents are called

· distributive property  - the distributive property of binary operations generalizes the distributive law from Boolean algebra and elementary algebra

· using estimation - Estimation is the process of finding an estimate, or approximation, which is a value that is usable for some purpose even if input data may be incomplete, uncertain, or unstable.

· steps to solve an equation  - Simplify each side of the equation by removing parentheses and combining like terms.  Use addition or subtraction to isolate the variable term on one side of the equation.  Use multiplication or division to solve for the variable.

· writing inequalities  - A number sentence used in algebra is called an inequality. An inquality is used when we don't know exactly what an expression is equal to. Instead of an equals sign, we can use one of these symbols: > greater than.

· solving inequalities  - "Solving'' an inequality means finding all of its solutions. A "solution'' of an inequality is a number which when substituted for the variable makes the inequality a true statement. ... Adding/subtracting the same number on both sides. Example: The inequality x-2>5 has the same solutions as the inequality x > 7.

Step-by-step explanation:

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
