Answer:
5mph over the speed limit
Step-by-step explanation:
In 1 hour the man drove 210/3.5=60 miles. 60mph is over the speed limit (55) by 5 mph.
Answer: x = -4
Step-by-step explanation:
1/2 * (x - (-6)) = 1
distribute
1/2x + 3 = 1
isolate the variable
1/2x = -2
x = - 4
Use the GCF of the terms to write the expression as the product of two factors with integer coefficients.
-2x3 - 4x2 + 4x
Hi. I was unsure of what exactly you wanted from this equation, so here's a quick analysis:
<em>f(x) = 2(x - 3)^2 - 2</em>
<em></em>
Domain: (-∞, ∞)
Range: (-2, ∞)
X-intercepts: (4, 0), (2, 0)
Y-intercept: (0, 16)
Axis of Symmetry: x = 3
Minimum value (vertex): (3, -2)
Standard form: y = 2x^2 - 12x + 16
