Answer:
The answer depends on what the problem really is.
f(1/2) = 8
or
f(1/2) = 4
See below.
Step-by-step explanation:
This is the problem as it was posted:
y = f(x) = 16x
Let x = 1/2
y = f(1/2) = 16(1/2) = 8
Perhaps the problem is this:

If x is an exponent of 16 and not a factor, then the answer is:

Answer:
560 seconds.
Step-by-step explanation:
Step-by-step explanation:
1-

calculate the powers behind the brackets from left to right
2-

Calculate the powers (a power squared means the number times itself so 2 squared equals 4)
3-

Calculate the sum ( minus minus equals plus so for example 4- -5= 4+5=9)
4- 49+5+2= 56
Answer:
There are 9 nickels and 11 pennies
Step-by-step explanation:
Systems of equation:
x=nickels
y=pennies
0.56=0.05x+0.01y
x+y=20
Answer:
x=-33/5 y=29/5
Step-by-step explanation:
Let's solve your system by substitution.
3x+y=−14;2x−y=−19
Solve
3x+y=−14 for y:
3x+y=−14
3x+y+−3x=−14+−3x(Add-3x to both sides)
y=−3x−14
Next is to substitute −3x−14 in for y 2x−y=−19:
2x−y=−19
2x−(−3x−14)=−19
5x+14=−19(Simplify both sides of the equation)
5x+14+−14=−19+−14(Add -14 to both sides)
5x=−33 Dived both sides by 5
5x/5=-33/3
x=−33/5 since you can't dived and a fraction is another form of division you keep it this way.
Step: Substitute -33/5 for x in y=−3x−14:
y=−3x−14
y=−3(-33/5)-14
y=29/5
(Simplify both sides of the equation)(since you can't dived and a fraction is another form of division you keep it this way.)
So
x=-33/5 and y=29/5
Pls mark brailest this took me a long time to write out lol. Hope this truly helps! Send a heart if so, so I can keep spreading the help!
