Answer:
<em>x = 1</em>
<em>y = 1</em>
Step-by-step explanation:
<u>System of Equations</u>
We are given the system of equations:
2x + y = 3
x = 2y - 1
Substituting x in the first equation:
2(2y - 1) + y = 3
Operating:
4y - 2 + y = 3
5y = 3 + 2
y = 5/5 = 1
y = 1
Since:
x = 2y - 1
Then:
x = 2(1) - 1
x = 1
Solution:
x = 1
y = 1
Answer:
THere will be 8 heads and 2 tails
Step-by-step explanation:
I don't know
The answer is 6 pi because you have to divide 18 by 3. That gives you 6.
f(3) = 1.9
Solution:
Given function:
To find f(3):
Substitute x = 3 in the given function.
Let us first simplify 
.
Apply exponent rule: 
The value of 
. (using calculator)
Substitute this value in f(3).
f(3) = 1.9
Hence the value of f(3) is 1.9.
