Solve using substitution.

-5x + 10y = -10
y = -2

Point Form:

( − 2 , − 2 )

Equation Form:

x =  − 2 ,  y =  − 2

Step-by-step explanation:

Solve for the first variable in one of the equations, then substitute the result into the other equation.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
