7. Evaluate the function rule for the given value. f(x) = 15x for x = 3

A. 14,348,907
B. 45
C. 3375
D. 225

45

Step-by-step explanation:

f(×) = 15x

f(3) = 15(3)

= 45

give brainliest please I need it to level up

C. 3375

Step-by-step explanation:

c.3375  

since x is 3 you then type the equation like this 15^3 and multiply 15 three times  

15^3

Given  :  for x =3.

To find : evaluate the function rule for the given value.

Solution : We have given  .

For x = 3.

Rule :  If  

Then   = 15*15*15.

 = 3375.

Therefore,  = 3375.

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
