f+7=12 is the equation so, f=5

f = 54

19 = f + 5 Subtract 5 from both sides: 14 = f

1/3 + f = 3/4 subtract 1/3 from both sides: f = 3/4 - 1/3 = 9/12 - 4/12 = 5/12

It is [(2a+2h+5) - (2a+5)]/h = 2h/h = 2

If: 5f+3 = 28 then f = 5 because (5*5)+3 = 28

wth??

g(x) = 5. So whatever f(x) or f(-1) is, g of that is going to be 5.

Only if it's a function.

g(x) = x + 3 Then f o g (x) = f(g(x)) = f(x + 3) = sqrt[(x+3) + 2] = sqrt(x + 5)

f = 1

The equation F X 2X plus 5 equals 0.5. This is a algebra math problem.

F = 41.5 9/5 + 32 is the conversion factor from Celsius to Fahrenheit.

That's going to depend on the values of 'a', 'b', 'c', and 'f'.

All of them

12 inches in a foot

F = 9/5 C + 32 = (9/5) x 10 + 32 = 18 + 32 = 50

yes

f(x) = x2 + 3 ----> f(5) = (5)2 + 3 ----> f(5) = 28

gf(5) = g(f(5)) = g(5+1) since f(x) = x+1 and then g(6) = 3*6 - 2 = 18 - 2 = 16

Interpreting the question as "evaluate f(x) = -x2 + 5 for x = 4". This is the same as asking "what is f(4)". To evaluate f(4) just replace each instance of the x in the definition of f(x) by the number 4: f(4) = -42 + 5. The result is -11.

s=5 f+s=? Substitute 5 in for s.Substitute 1 in for f.f+s=f+5f=11+5 ={6}

find f'(x) and f '(c)f(x) = (x^3-3x)(2x^2+3x+5
