Find attached the document with both graphs.

The remarks are:

- both graphs have the same shape: open downward, same symetry axis, same, x-coordinate of the vertex.

- the maximum value of -2x^2 is 0

- the maximum value of -2x^2 + 4 is 4

- the graph of y = -2x^2 + 4 is the graph -2x^2 shifted 4 units upward as consecuence of having summed 4 to the function.

Connor rolled a die 6 times. A 2 occurred three times. Why isn't the theoretical probability 3/6 instead of 1/6?​
Cerrena [4.2K]

2 occurred 3times

\\ \sf\longmapsto S=6\times 3=18

\\ \sf\longmapsto |S|=18

Now

\\ \sf\longmapsto E=No\:of\:times\: 2\:occured

\\ \sf\longmapsto |E|=3

we know

\boxed{\sf P(E)=\dfrac{|E|}{|S|}}

\\ \sf\longmapsto P(E)=\dfrac{3}{18}

\\ \sf\longmapsto P(E)=\dfrac{1}{6}

Transform the equation 3x + y = 5 into slope-intercept form.
marin [14]

Answer: y=-3x+5

Step-by-step explanation:

Slope-intercept form is y=mx+b. So to make your equation into slope-intercept form, simply subtract 3x from both sides, which results in y=-3x+5
