Answer:
y = ½x
_____
k = ½
Step-by-step explanation:
[# of donuts] 2 → [total price] $1
[# of donuts] 12 → [total price] $6
[# of donuts] 3 → [total price] $1.50
[# of donuts] 7 → [total price] $3.50
Because price is the dependent variable, it is the y value. And since the price is the y variable, the donuts must be the x value.
Because the price is ½ the # of donuts, y is ½ x which means y = ½x and k = ½.
Answer:
f(x)=5x^2-4x+5
Step-by-step explanation:
A quadratic function always has a squared symbol (represented by ^2). The first answer is a linear function, the second answer is a linear function (squaring 0 results in 0, therefore it is canceled out), the third answer has ^2 (this is correct), and the fourth answer has a ^3 (this is a cube function; not quadratic)
I answer this question atleast once a day hahah.
Firstly convert 1/2 into quarters.
1/2 = 2/4 (double the numerator and denominator)
Then add the two, 2/4 + 1/4 (add the numerators)
2/4 + 1/4 = 3/4
The answer is: 3/4
