Toys for tots collected 100 toys on saturday. if this was 80% of the goal the set to collect over the weekend, what was their goal?

Their goal was to collect 125 toys.

Step-by-step explanation:

=

Whatever you do to one side you must do to another. To get from 80 to 100% of your goal, you must multiply 80 by 1.25 . Because we did this to one side, we had to do it to the other. 100 toys multiplied by 1.25 is 125 toys.

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
