Answer:
The price of a medium pizza with 3 toppings is $15.
Step-by-step explanation:
If "t" represents the number of toppings, you will use the expression "9+2t" and plug in 3 for t (since there are 3 toppings)
So it will look like:
9+2(3)
Then you're gonna use PEMDAS, multiply 2*3
9+6
And then you get an answer of $15
Hope this helps :))
(a) One possibility is 8.45
Rounded to the nearest integer = 8
Rounded to the nearest tenth = 8.5
And rounding this to the nearest integer = 9
(b) The possible numbers are 8.45 to 8.49, inclusively
Answer: C
Step-by-step explanation: Hope this help :D
Half the x-coefficient is -3, so the equation needs to be rearranged into a form that looks like
x² -6x +(-3)² + [something]
You can get there by adding and subtracting 9 from the original equation.
y = x² -6x +9 +7 -9 . . . . . 9 added and subtracted
y = (x² -6x +9) -2
The quantity in parentheses is a perfect square, so we can write the equation in the desired form as ...
y = (x -3)² -2
