Answer:
f(y) = 4y2 - 4v
f(y) = 4y² - 4(-4) = 4y² + 16
f(y) = 4y² - 4(-3) = 4y² + 12
f(y) = 4y² - 4(-2) =4y² + 8
f(y) = 4y² - 4(-1) = 4y² + 4
Step-by-step explanation:
We know that
The sum of the lengths of any two sides of a triangle is greater than the length of the third side (Triangle Inequality Theorem)
Let
A------> Lincoln, NE
B------> Boulder, CO
C------> third city
we know that
in the triangle ABC
AB=500 miles
BC=200 miles
AC=x
Applying the Triangle Inequality Theorem
1) 500+200 > x------> 700 > x------> x < 700 miles
2) 200+x > 500----> x > 500-200------> x > 300 miles
the solution for x is
300 < x < 700
the interval is------> (300,700)
the possible distances, d, in miles, between Lincoln, NE, and the third city, are in the range between 300 and 700 miles
I'm pretty sure it's A. 7+x+4y, but I could be wrong.
Y = -5x -5
To check, we can insert 0 for y and -1 for x
0 ? (-5X-1) - 5
0 ? 5 - 5
0 = 0
So yes, the equation is correct
Answer:
7.
(x + 1)² = x² + 2x + 1
as the original function, but the turnaround is now (still at x = 0) at y = 1 instead of y = 0.
and the graph is "narrower". for x = 1 and x = -1, y = 4. for x = 2 and x = -2, y = 9
8.
= x² - 2
it is exactly the same graph, just 2 units down in y direction (the turnaround is at x = 0. y = -2).
9.
the right answer is D
Step-by-step explanation:
9.
the y values of +x values now become the same values for the -x values. and vice versa.
