What is the equation in standard form of a parabola that models the values in the table y=-4x^2+3x+5 y=-4x^2-3x+5 y=3x^2-4x+5 y=4x^2-3x+5

Y=4x^2-3x+5

Step-by-step explanation:

For the standard form equation to model the values in the table, each value of x in the table should give the matching the y value when substituted into the equation. We will test each equation:

for (-1,12)

This does not give 12 as the answer and is not a solution.

for (-1,12)

This does not give 12 as the answer and is not a solution.

for (-1,12)

This does give 12 as the answer and is a possible solution.

We now try (2,15).

This does not give 15 as the answer and is not a possible solution.

for (-1,12)

This does not give 12 as the answer and is not a solution.

We now try (2,15).

This does give 15 as the answer and is a solution.

This is the standard form of the equation.

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!
