How do you find the value of X? Isosceles and Equilateral Traingle

The border line of the linear inequality 4x + 7y < 5 is dotted true or false?

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
