Step-by-step explanation:
x - 7 < -20
x < -20 + 7
x < -13
X = (-12, -11, -10,...)
-2
The coefficient is the number in front of the value.
Answer:
The side lengths are 9, 9 and 7.
Step-by-step explanation:
The sum of the 2 equal sides plus the shorter side is 25 ft.
Representing these unknowns:
2 sides are of length s, and the third (shortest) side is then s - 2.
Thus, s + s + (s - 2) = 25, or 3s = 27. Thus, s = 9 and s-2 = 7
The side lengths are 9, 9 and 7.
Please, use " ^ " to denote exponentiation: p(t) = t^2 + 5t + 6.
To find the critical points, differentiate p(t) with respect to t, set the result = to 0, and then solve the resulting equation for t:
p '(t) = 2t + 5 = 0
Solving for t: 2t = -5, and so t = -5/2. (-5/2, p(-5/2)) is the critical point. That evaluates to (-5/2, -0.25). This happens to be the vertex of a parabola that opens up.
