Answer:
-4
Step-by-step explanation:
(-2)^2=4 because a negative number squared is always positive
-(2)^2=-4
Answer:First inequality: y >

Second inequality: y < 3 + x
Explanation:The inequality in slope-intercept form has the following general formula:
y < mx + c or y > mx + c (according to the given sign)
where m is the slope and c is the y-intercept
This means that to get any inequality in slope-intercept form, we will have to isolate the y on one side of the inequality.
First given inequality:4x - 5y < 1
4x - 5y + 5y < 1 + 5y
1 + 5y > 4x
1 + 5y - 1 > 4x - 1
5y > 4x - 1
y >

comparing this to the general form, we would find that:
slope (m) = 4/5
y-intercept (c) = 1/5
Second given inequality:y - x < 3
y - x + x < 3 + x
y < 3 + x
comparing this to the general form, we would find that:
slope (m) = 1
y-intercept (c) = 3
Hope this helps :)
I am not sure, but the best answer should be 8 miles per hour
One of the methods of separation of homogeneous mixtures is called distillation and it is based on the various boiling points of the component of mixture. Heating the mixture, the component that has the lowest boiling point will evaporate and the separation can be done. the other method is called chromatography.so the answer is d.distillation! hope this helped!
