Answer:
option A
f(x) = (x – 1)2 + 3
Step-by-step explanation:
Given in the question a function,
f(x) = 4 + x² – 2x
<h3>Step 1</h3>
f(x) = 4 + x² – 2x
here a = 1
b = -2
c = 4
<h3>
Step 2</h3>
x = -b/2a
h = -(-2)/2(1)
h = 2/2
h = 1
Step 3
Find k
k = 4 + 1² – 2(1)
k = 3
Step 4
To convert a quadratic from y = ax² + bx + c form to vertex form,
y = a(x - h)²+ k
y = 1(x - 1)² + 3
y = (x - 1)² + 3

Answer:
Step-by-step explanation:
first lets find out how much she spent
1 x $13 = $13 for the coffee (i dont know if im missing the amount of pounds bc there is no number there so if i am im sorry :/ )

hope this helps <3
Answer:
1,680 grams
Step-by-step explanation:
To solve this, we can create a proportion using this setup:
grams/people=grams/people
The recipe needs 480 grams for 4 people and x (unknown-what we are trying to find) grams for 14 people.
480 grams/4 people=x grams/14
480/4=x/14
Now, we have to solve for x-the grams needed for 14 people. To do this, we have to get x by itself. x is being divided by 14. To undo this, multiply both sides by 14, because multiplication is the opposite of division.
14(480/4)=(x/14)14
14(480/4)=x
14*120=x
1680=x
She needs 1,680 grams of couscous for 14 people.
