Sally found 58 seashells on the beach, she gave jason some of her seashells. she has 28 left. how many seashells did she give to jason?

Sally gave 30 shells to Jason

Solution:

Given that, Sally found 58 seashells on the beach, she gave Jason some of her seashells

She has 28 left

To find: Number of sea shells she gave to Jason

From given,

Total number of shells she found = 58

Remaining shells = 28

Therefore,

Number of sea shells she gave to Jason = Total number of shells she found - Remaining shells

Number of sea shells she gave to Jason = 58 - 28 = 30

Thus Sally gave 30 shells to Jason

answer: it's d

step-by-step explanation:

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
