Use equation 1 and equation 2 to eliminate the variable 3x - y - 6z = 16 equation 1
-x - 2y + z = -5 equation 2
2x + 3y + 2z = 10 equation 3

Lassify the function as linear or quadratic and identify the quadratic, linear, and constant terms. f(x) = (3x + 2)(−6x − 3) linear function; linear term: −21x; constant term: −6 linear function; linear term: −18x2; constant term: −6 quadratic function; quadratic term: 6x2; linear term: 24x; constant term: −6 quadratic function; quadratic term: −18x2; linear term: −21x; constant term: −6

Can someone check if i did this correct. it’s number 4 if you’re wondering.

Which inequality is equivalent to -3x < -12? x < 4 , x < -4 , x > 4, x > -4
