Simplify the expression.
Answer:
x = 99 degrees.
Step-by-step explanation:
The angle in the triangle adjacent to 123 = 180 - 123 = 57 degrees.
m < x = 42 + 57 = 99 degrees. ( by the external angle of triangle theorem).
A strong negative correlation example would be the hours spend watching TV and your grades. It shows a strong negative correlation because if you just watch TV and not study for an exam, your grades would most likely be low.
Answer:
Step-by-step explanation:
x^2 + 3x - 9 =0
By comparing with the equation ax^2+bx+c = 0,
we get,
a = 1, b=3, c = -9
we know the formula for x is,
x = (-b±√(b^2 - 4ac))/2a
x = (-3±√45)/2
x = (-3±3√5)/2
x = (-3+3√5)/2, (-3-3√5)/2
