For this, we use the FOIL method of expanding brackets; start by multiplying the FIRST terms of each bracket together to get xx=x^2. Next multiply the OUTSIDE elements, ie the first element in the first bracket and the last in the second, giving x(-5)=-5x. Then comes the INSIDE elements, giving 4x=4x, and finaly the LAST elements of each bracket, giving 4(-5)=-20. Adding all these terms together gives us our answer; x^2+4x-5x-20, which can be simplified to x^2-x-20.
Hope this helps!
You will need 50 because 10 divided by 500 is 50 so you will need 50 markers.<span />
1. (3x-2)/4+1=5
2. (3x-2)/4+1-1=5-1
3. (3x-2)/4=4
4. (3x-2)/4+2=4+2
5. this is the mistake, wecan't just add them because the fractions aren't the same
(3x-2)/4 plus 2/1, the bottom numbers areen't the same
what should be done is go back to step 4 and mltiply both sides by 4, don't add 2
results in
5. 3x-2=16
6. 3x=18
7. x=6
A production isoquant is drawn on a graph with labor on one
axis, capital on the other. Isoquants usually have a concave shape.
The isoquant represents the mix of capital and labor that will produce a
given, fixed level of output.
Answer:
y=2x
Step-by-step explanation:
From (0,0) to (3,6), it is 3 units to the left and 6 units left, divide that so you can have 1 unit to the left and 2 units up. Therefore, the answer is y = 2x.
