I Hope That I Am Not To Late, But The Answer Is D (7,4) <3
<u>Explanation </u>
2 x 7 = 14
5 x 4 = 20
14-20= -6
>>>
2 x 7= 14
7 x 4 = 28
14-28= -14
X= 7 & Y=4
Once again sorry if i am late, if others come I hope this helps UwU
The unit rate with the turtle crawling is 6/23 mile per hour.
According to the statement
we have given that the every 1/3 of an hour that the turtle is crawling, he can travel 2/23 of a mile. and
we have to find the unit rate with the turtle crawling
So, For this purpose,
we know that the
The unit rate of speed in miles per hour the number of miles in one hour.
So, to find the unit rate:
Divide distance in miles with the time which is in hours.
So,
unit rate of speed = distance / time
unit rate of speed = (2/23) / (1/3)
unit rate of speed = 6/23 mile per hour.
So, The unit rate with the turtle crawling is 6/23 mile per hour.

Answer:
f(x) = 6x² - 24x + 21
Step-by-step explanation:
The equation of a quadratic function in vertex form is
f(x) = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k ) = (2, - 3 ) , then
f(x) = a(x - 2)² - 3
To find a substitute (1, 3 ) into the equation
3 = 1(1 - 2)² - 3
3 = a(- 1)² - 3
3 = a - 3 ( add 3 to both sides )
6 = a
f(x) = 6(x - 2)² - 3 ← in vertex form
= 6(x² - 4x + 4) - 3
= 6x² - 24x + 24 - 3
f(x) = 6x² - 24x + 21 ← in standard form
