Answer:
c = -4
Step-by-step explanation:
If f(x) = 2x^3 - x + c and f(2) = 10, plug in 2 for the x values in the function and make the function output 10.
10 = 2(2^3) - 2 + c Now, we only have to deal with one variable, that is c.
10 = 2(8) - 2 + c
10 = 16 - 2 + c
10 = 14 + c
-4 = c After simplifying, we get that c is -4.
To check this, plug in 2 for x, and -4 for c in the function. If the function produces 10 as the result, the halleluja!
f(2) = 2(2^3) - 2 - 4
f(2) = 2(8) - 2 - 4
f(2) = 16 - 2 - 4
f(2) = 10
1300
is the correct answer
Answer:
Option 2, 3, 4
Step-by-step explanation:
It cannot be the 1st option because a linear function doesn't have an
and adding an x to an x will not make it squared. ax + by = c is the linear equation.
It can be the 2nd option because the quadratic formula is f(x) = a
+ bx + c and the middle portion could cancel when adding 2 together.
It can be option 3, because f(x) = a
+ bx + c plus ax + by = c could give you the resulting function f(x) = -3
+5
It can be option 4 because multiplying ax + by = c by ax + by = c would give you an
.
It cannot be option 5 because a
+ bx + c multiplied by a
+ bx + c would give you a function with 
Answer: There were 350 hamburgers sold.
Step-by-step explanation:
x + (x +73)= 773 where x is the number of hamburgers sold and (x+ 73) is the number of cheese burgers sold.
x + (x+ 73)=773
2x + 73 = 773
2x + 700
x= 350
1(350)= 350
