F(x) = input the x
3x+2
multiply it by 3 and add 2
3*x+2=
3*5+2=
15+2 =
17
or if you meant 2x:
it would be the same just do:
3+2x
3+2*5
3+10
13
Answer:
tan(5x/8)
Step-by-step explanation:
given expression
Using the trigonometric identity
tan(a+b)=
here a= 1/2x and b=1/8x
putting the values we get
=tan(1/2x+1/8x)
=tan(5/8x)!
Answer:
10 lb of cashews and 70 lb of peanuts
Step-by-step explanation:
Let x = the pounds of cashews.
Then 80 – x = the pounds of peanuts
Value of cashews + value of peanuts = volume of mixture
x×4.75 + (80 – x)×2.75 = 80×3 Remove parentheses
4.75x + 220 - 2.75x = 240 Combine like terms
2.00x + 220 = 240 Subtract 220 from each side
2.00x = 20 Divide each side by 2.00
x = 10 lb
80 - x = 80 – 10
80 - x = 70 lb
Max will mix 10 lb of cashews with 70 lb of peanuts.

<em>Check:
</em>
10×4.75 + 70×2.75 = 80×3.00
47.50 + 192.50 = 240.00
240.00 = 240.00
