Answer:
- x-intercept: 82.75
- y-intercept: 2.15
Step-by-step explanation:
A graphing calculator can show you the intercepts.
___
Or you can figure them out.
The y-intercept is where x=0, so is ...
y = log(12·0 +7) -3 = log(7) -3 ≈ -2.1549 ≈ -2.15
___
The x-intercept is where y = 0, so is ...
0 = log(12x +7) -3
3 = log(12x +7) . . . . . . add 3
10^3 = 12x +7 . . . . . . . take the antilog
993 = 12x . . . . . . . . . . subtract 7
993/12 = x = 82.75 . . . divide by the coefficient of x
Answer:
y = 12x
Step-by-step explanation:
Given that:
y = cost of making a special order cupcake
A dozen of special order cupcakes = 12 pieces
Let the cost of extra ingredient for making a special order cupcake = x
Hence the cost y of making a dozen of such special order will be :
y = extra cost per order * number of orders
y = 12x
Answer:
7%, .15, 4/25, .28
Step-by-step explanation:
7% is 0.07 because it mean per hundred. .15 is next because when you divide 4/25 you get 0.16 so yeah then 4/25 is third then .28 is last because it is the greatest.
5/3 × 5/3 × 5/3 = 4 17/27
I hope this helps!!!
