Answer: 46
Step-by-step explanation:
You can simplify this using PEMDAS:
Parentheses
Exponents
Multiplication/division
Addition/subtraction
Move through the steps in that order.
In this case, the first two steps are absent, so multiply first:
20 - 16 + 42
Then, add and subtract:
46.
Answer:
you are only rolling 1 dice the probability of getting 9 is 0 there are only 6 sides to one die
(a) since we are given that f(8) = 9, the inverse of 9 is simply 8. Therefore, f^-1(9) = 8.
(b) Again, f is the inverse of f^-1, therefore, you simply switch numbers, and you get that f(-3) = -7.
<em><u>should be G : y=2x+1</u></em>
Answer:
x=2, y=1. (2, 1).
Step-by-step explanation:
y=3x-5
6x+3y=15
-----------------
6x+3(3x-5)=15
6x+9x-15=15
15x-15=15
15x=15+15
15x=30
x=30/15
x=2
y=3(2)-5=6-5=1
