Answer:
y = 2x^2 is a parabola opening up with it's vertex at (0,0)... y=3x^2 -4 is also a parabola opening up, but it is 'thinner' in that it rises in y faster and it's vertex is at (0,-4)
Step-by-step explanation:
all equations of the type y = ax^2 + b are parabolas centered on the y-axis, soo the vertex is always on (0,b)
If a is positive then the parabola opens up,
the bigger a is, the 'thinner' the graph is, i.e. the faster the graph rises
the value of b determines the location of the vertex, if b is added, then the vertex rises over the x-axis, if b is subtracted then the vertex is below the x-axis
Answer:
74degrees............. use tanx=31/10
Answer:
(6, -4) does not fit with these two equations
Step-by-step explanation:
y = 8 - 2x
x + 3y = 12
fit (6, -4) into the equations
-4 = 8 - 2(6)
8 - 2(6) = 8 - 12 = -4
works for this one
6 + 3(-4) = 12
6 + 3(-4) = 6 - 12 = -6
doesnt work for this one
Answer:
5m^5n^4
Step-by-step explanation:
Divide the length (5m^4n^2) into the area (25m^9n^6) to obtain the width:
25m^9n^6
----------------- = 5 m^(9-4)n(6-2) = 5 m^5n^4
5 m^4n^2
The width of the rectangle is 5m^5n^4.
