Is (0,-1)(0,−1)left parenthesis, 0, comma, minus, 1, right parenthesis a solution of -10x +4y \geq -4−10x+4y≥−4minus, 10, x, plus, 4, y, is greater than or equal to, minus, 4 ?

14. (05.02 lc) what is the value of y in the solution to the following system of equations? (5 points) 2x + y = −4 5x + 3y = −6

Which sum or difference identity would you use to verify that cos (180° - q) = -cos q? a.) sin (a -b) = sin a cos b – cos a sin b b.) cos (a -b) = cos a cos b – sin a sin b c.) cos (a -b) = cos a cosb + sin a sin b d.) sin (a + b) = sin a cos b + cos a sin b

Whit h equation best represents this situation the number 98 increased by an unknown number equal to 120
