Answer:
6x - 9y = -12
Step-by-step explanation:
2x - 3y = -4 multiply both sides by 3 by adding paranthesis to represent this
3( 2x - 3y ) = 3 (-4) Then use distributive property for the left side equation
6x - 9y = -12 Finally just multiply -4 by 3 and you get this equation

Answer:
T > -9/28
Step-by-step explanation:
A quadratic has two real solutions when the discriminant (b² - 4ac) is positive.
b² - 4ac > 0
3² - 4(T)(-7) > 0
9 + 28T > 0
28T > -9
T > -9/28
