Use substitution.
y = 2 - x and y = 4x + 7 can become
2 - x = 4x + 7
Now solve for x
-5 = 5x
-1 = x
Now plug -1 for x in either equation.
y = 2 - x -> y = 2 - (-1) -> y = 3
y = 4x + 7 -> y = 4*-1 + 7 -> y = -4 + 7 -> y = 3
So C) is the correct answer.
Answer:
open circle at 7; arrow points left
Step-by-step explanation:
To Solve:
4x - 10 < 18
+ 10 +10
4x < 28
/4 /4
x < 7 *only flip sign when multiply/divide by negative
< means the arrow will point left and that it will be an open circle
Given that <span>work hours in new zombie are 200 in year 1 and productivity is $8
per hour worked.
The new zombie's real gdp in year 1 is given by 200 x $8 = $1,600
If work hours increase
to 210 in year 2 and productivity rises to $10 per hour.
The new zombie's real gdp in year 2 is given by 210 x $10 = $2,100
The new
zombie's rate of economic growth is given by
