Hello,
First, you must understand that
(f-g)(x) means f(x)-g(x) it is the difference of two functions :
f(x)=2x+4 and g(x)=3x-7
f(5)=2*5+4=10+4=14
g(5)=3*5-7=15-7=8
So, (f-g)(5)= f(5)-g(5)=14-8<u>=6</u>
Answer A: none of the choices are correct.
An other way to do it:
(f-g)(x)=f(x)-g(x)=2x+4-(3x-7)= 2x-3x+4+7=-x+11
if x= 5 then (f-g)(5)=-5+11<u>=6</u>
Answer:
1) 19³=6859
2) 16² =256
3) 15³ =3375
4) 20² =400
5) 10³ =1000
Step-by-step explanation:
using your calculator to (square = number times itself) or (cube = number times itself times itself again)
Answer:
2y^2 + 5y
Step-by-step explanation:
the two y squared add up to 2 y squared
11y - 6y = 5y
Answer:
0.390 to the nearest thousandth or 39%.
Step-by-step explanation:
That would be 0.79^4
= 0.3895.
The probabilities are multiplied because each selection is independent.
I hope this helps you
