Answer:
( 2x +3 ) (x-4 )
Step-by-step explanation:
2x²-5x-12
Factor
( 2x ) (x )
We need to look at the factors of -12
-1 *12 -2 *6 -3*4 -4*3 -6*2 -12*1
What multiplies 2 * 1st factor + the other factor to equal -5
2* -4 +3 = -8+3 =5
so the -4 goes on the outside and the 3 goes on the inside
( 2x +3 ) (x-4 )
Answer:
Thomas' real income now is half that it was (nominal income decreased by half or prices doubled)
Step-by-step explanation:
If you graph both cases you will see that the shift is parallel between one case and the other.
Changes in relative prices (this is, if only one of the goods change prices), would cause a rotation in the budget line
Answer: The first option.
Step-by-step explanation:
1. You need to remember that:
- An even function is a function with the following property:
f(-x)=f(x)
- An odd function is a function with the following property:
f(-x)=-f(x)
2. By definition, the contangent is an odd function, therefore you have that:
cot(-θ)=-cot(θ)
Then:
3. So, you can coclude that the first step is wrong. Therefore, the answer is the first option.
Answer:
1. -2
2. -10
3. -8
Step-by-step explanation:
1. you add 4 to -3 which is equal to one then you multiply 1 by -2 which is -2
2. 4-2=2 then 2(-5) is equal to -10
3. -7+3=-4 and 4-5 is equal to -1 then you multiply that by 2 which is equal to -2
