2 > x > -1 is the inequality.
7/9 is equivalent to <span>0.7777777. Since the 7 keeps repeating and has no visible end, it repeats.</span>
Answer:
D
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - x - 2 ← is in slope- intercept form
with slope m = -
Given a line with slope m then the slope of a line perpendicular to it is
= - = - = , thus
y = x + c ← is the partial equation of the perpendicular line
To find c substitute (- 12, 7) into the partial equation
7 = - 16 + c ⇒ c = 7 + 16 = 23
y = x + 23 → D
The 4 legged stool will rock. the 4 ends of the legs form a plane. they cannot sit on an uneven surface. the area they sit on must be planar. the 3 legged stool, however, can sit without rocking, because any 3 points define a plane entirely
