4th one btw I was a prospect elite on Brainly but I got banned
Answer:
The U.S. PPF rotates outward (abticlockwisely), increasing the x-axis intercept with no change in the y-axis intercept
Step-by-step explanation:
Fracking is a method of improving production capabilities on oil and gas production. Although, it usually leads to environmental pollution later, it does bring in higher yields of oil and gas.
If the oil and gas production on the x-axis increases without a simultaneous, almost equal increase in production of other goods and services (on the y-axis), the data points for the x-axis shift more to the right and the PPF rotates more anti-clockwisely outward, thereby increasing the intercept on the now improved x-axis and not too much change on the intercept of the y-axis.
Answer:
x = -1, and y = -2, giving you the answer (-1, -2)
Step-by-step explanation:
In the second equation, we're told that y is equal to 2x. With that, we can replace "y" in the first one with "2x", giving us:
-4x - 2x = 6
-6x = 6
x = -1
Now that we know the value of x, we can simply plug it into the first equation to find y:
-4x - y = 6
-4(-1) - y = 6
4 - y = 6
-4 + y = -6
y = -6 + 4
y = -2
So x = -1, and y = -2
