Jaime has 38 marbles if Jorge had 14 more marbles he would have twice as many as Jaime how many marbles does Jorge have now?
Ganezh [65]

Answer:  Jorge has 62 marbles.

Step-by-step explanation:  Given that Jaime has 38 marbles if Jorge had 14 more marbles he would have twice as many as Jaime.

We are to find the number of marbles that Jorge has.

Let x and y represents the number of marbles that Jalme and Jorge has respectively.

Then, according to the given information, we have

x=38

and

y+14=2x\\\\\Rightarrow y+14=2\times38\\\\\Rightarrow y+14=76\\\\\Rightarrow y=76-14\\\\\Rightarrow y=62.

Thus, Jorge has 62 marbles.

Answer:

Vertex → (2, 4)

Step-by-step explanation:

Quadratic equation has been given as,

y = -x² + 4x

We rewrite this equation in the form of a function as,

f(x) = - x² + 4x

By comparing this equation with the standard quadratic equation,

y = ax² + bx + c

a = -1 and b = 4

Vertex of the parabola represented by this equation is given by [-\frac{b}{2a}, f(\frac{-b}{2a})]

x coordinate = -\frac{4}{2(-1)}

                     = 2

y-coordinate = f(2)

                     = - (2)² + 4(2)

                     = -4 + 8

                     = 4

Therefore, vertex of the given function is (2, 4)
