Answer:14
Step-by-step explanation:
Please be certain to use " ^ " to denote exponentiation:
3x^2 + 4x – 5, 7x^2 + x + 9, 4x^2 - 3x
First, perform this subtraction:
7x2 + x + 9
-(3x2 + 4x – 5)
-----------------------
4x^2 - 3x + 14
Next, subtract 4x^2 - 3x from the above result:
4x^2 - 3x + 14
-(4x^2 - 3x)
------------------------
14 (answer)
For scientific notation, you always want 1 digits in front of the decimal.
Ex) 7.39*10^5
Move the decimal point in between the 1 and 4, or 1 place to the left.
1.435
Since the decimal point was moved 1 place to the left, the exponent after 10 will be 1.
1.435*10^1
1.435*10^1 is your final answer.
1.435*10 is the same thing also.
Both angles equal 73, according to the vertical angle conjecture. To solve for x:
(1+2x)=73
2x=72
x= 36
When it says "the subject", it only means you need to isolate the x, or solve for x. To do that, we have to get the x by itself. But how can we do that? We'll have to get rid of that pesky -5. Well, what can we do to -5 to get to 0? Of course -- Add 5!
b=x-5
+5
But whatever we do to one side of the equation, we have to do to the other.
b=x-5
+5 +5
We're left with b+5=x. There's your answer!
