Answer:
3/2
Step-by-step explanation:
if you multiply 3/2 by 2 and add 7 you will get 10.
3/2 * 2 = 3
3 + 7 = 10
Answer:
x/5
Step-by-step explanation:
To get the inverse function you need to leave the x alone and then switch variables ( f(x) = y)
f(x) = 5x
y = 5x
y/5 = x
Now that x is alone you switch the x for y and the y for x and you get:
x/5 = y
And this new y is the inverse function of f(x) ( f^-1(x))
f^-1(x) = x/5
<span>Let the nickels be x and the dimes be y
x + y = 24
5x + 10y = 185
5x + 5y = 120
5y = 65
y=13
x=11
Answer: 11 nickels and 5 dimes</span>
False, 4-2(3+7) = -16 and 4-2•3+2•7= 12
