Answer: B: inverse Variation; xy= 20
Step-by-step explanation:
From the given table, it can be seen that when the values of x is increasing then the values of y decreasing .
Therefore, it is clear that there is inverse variation between x and y.
Also, the equation of inverse variation is given by :-
For x=2 and y=10, we have :
Now, the equation of inverse variation with k =20 will be :
Answer:
D. Minimum at (3, 7)
Step-by-step explanation:
We can add and subtract the square of half the x-coefficient:
y = x^2 -6x +(-6/2)^2 +16 -(-6/2)^2
y = (x -3)^2 +7 . . . . . simplify to vertex form
Comparing this to the vertex for for vertex (h, k) ...
y = (x -h)^2 +k
We find the vertex to be ...
(3, 7) . . . . vertex
The coefficient of x^2 is positive (+1), so the parabola opens upward and the vertex is a minimum.
3.4(x+1.58)= - 11.288
Step 1: Distribute 3.4 to the numbers inside the parentheses (x+1.58)
3.4x + (3.4×1.58)= - 11.288
3.4x + 5.372 = -11.288
Step 2: Bring 5.372 to the right side by subtracting it to both sides
3.4x + (5.372 - 5.372 ) = (-11.288 - 5.372)
3.4x + (0) = (-16.66)
3.4x = -16.66
Step 3: Isolate x by dividing 3.4 to both sides
x = -4.9
Hope this helped!
thsgs the best i can help but I think the line would be dashed not sure
