what is writing systems?
ex:
total number: a + c = 2200
total income: 4a + 1.5c = 5050

unit 6 system of inequities.
to graph a linear inequality in two variables (say, x and y ), first get y alone on one side.
200
what is number of solutions of a system?
The solution is where the equations 'meet' or intersect. The red point is the solution of the system.

unit 7 what is exponent rules?
The exponent says how many times to use the number in a multiplication. A negative exponent means divide, because the opposite of multiplying is dividing.
300
what is solving systems by substitution?
ex: −2x+7 − 2 x + 7
answer (x,5x−1)

what is multiplying polynomials.
Multiplying polynomials involves applying the rules of exponents and the distributive property to simplify the product. This multiplication can also be illustrated with an area model, and can be useful in modeling real world situations.
