By looking at the graph we can see that f(x) increase by 1 (on the vertical axis . or y-axis ) from 2 to 3, over the interval 0 to 1 ( horizontal axis, or x-axis)
It increases by 2 over the interval 1 to 2.
by 4 over the interval 2 to 3.
And by 8 over the interval 3 to 4.
Therefore this exponential function grows by a factor of 2 (since it doubles every by every interval of 1)
35% = 119 cupcakes
100% = ? cupcakes
(119*100)/35=11900/35=340 cupcakes
Answer: 340 cupcakes they sold that day
Hope it helped, good luck.
Answer:
All real numbers of x.
Step-by-step explanation:
5x+10=5(x+2) have the exact same equations on both sides.
5x+10=5x+10
If both are graphed, they will intersect each other for every value of x.
Answer:
To solve this you would do the following:
We know her plan is $15/monthly, regardless of any additional texts/calls she makes.
If 1 minute = $.20 worth of money, we would simply multiply 30 (she made 30 minutes worth of calls) x $.20 ($.20 for each minute). The product is $6.
So, $15 + $6 = $21.
Unless the amount owed per text is mentioned and you forgot to include it in the title, you would not need to take this into consideration.
