Step-by-step explanation:
The vertex of f(x) = x² is at (0, 0)
To find the vertex of g(x) = x² - 8x + 7 ← in standard form
The x- coordinate of the vertex is
= -
where a = 1 and b = - 8
= - = 4
substitute x = 4 into the equation for corresponding y- coordinate
y = 4² - 8(4) + 7 = 16 - 32 + 7 = - 9
The vertex of g(x) is at (4, - 9)
thus (0, 0) → (4, - 9) is 4 units right and 9 units down → option C
Answer:
60 days.
Step-by-step explanation:
Let the actual time be x, then:
x - 0.25x = 45
0.75x = 45
x = 45/0.75
= 60 days.

Step-by-step explanation:
Given
Beginning of Week
First, we calculate the amount Peter has at the beginning of the week
Make Peter the subject
When Josh gave out 25%.
The number (n) of computers is:
This means that Josh gave out 8 computers.
So, the amount they both have is:
Yes because 2 divided by 5 is .4 , and .4 is a decimals and decimals are in rational numbers .
