Answer:
Step-by-step explanation:
3/4 inch to 1 mile = 1 3/4(or 7/4 in) to x miles
make a proportion
(3/4) (7/4)
-------- = ------- cross multiply
1 x
(3/4)(x) = (7/4)(1)
3/4x = 7/4
x = (7/4) / (3/4)
x = 7/4 * 4/3
x = 7/3 or 2 1/3 miles <===
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
There are no directions to what we have to solve
Step-by-step explanation:
