4x-2y=7 (1)
-3x+3y=10 (2)
3y= 3x+10
y= x+10/3 (3)
sub (3) into (1)
4x-2(x+10/3)=7
4x-2x-20/3=7
2x-20/3=7
+20/3 +20/3
2x= 41/3
x= (41/3) / 2
x= 41/6
sub x= 41/6 into (3)
y= 41/6+10/3
= 61/6
Therefore the point of intersection is (41/6, 61/6)
Kinda like answer
answer is 36
To simplify that equation you would first subtract 8 from both sides, getting 7x=28. You would then divide both sides by 7, getting x=4.
Answer:
8
Step-by-step explanation:
The function u given me is
The period of a function is represented by
where b is the coefficient of the x variable.
The coefficient is pi/4 so
8 is the answer.
First of all, 2^n and 3^n are exponentials with different bases, and thus their sum cannot be simplified beyond 2^n + 3^n. In other words, these two functions cannot be combined ino one function (such as 4^n).
You may gain much more insight by graphing 2^n, 3^n and 4^n to determine whether there is truth in the given statement or not.
