Answer:
(-4, -5)
Step-by-step explanation:
-4x + 2y = 6
-4x + 2(x - 1) = 6
-4x + 2x - 2 = 6
-2x - 2 = 6
-2x - 2 + 2 = 6 + 2
-2x = 8
-2x/-2 = 8/-2
x = -4
------------------------
y = x - 1
y = -4 - 1
y = -5
-------------------------
-4(-4) + 2(-5) = 6
16 + -10 = 6
6 = 6
Answer:
x = 7
Step-by-step explanation:
Add 3x to both sides of the equation.
2x = 6+8
Divide both sides by 2.
x = 7
Answer: (5.7*10^5) = 570,000 and 1.9*10^6 = 1,900,000
so the answer is the sum o f it!
Answer:
or 
, since 
Step-by-step explanation:
According to the question the weight is rejected if it is more than 0.36 oz, the weight should not be beyond 0.36 oz that is from the target weight of 18.25.
We can say that, the difference between the actual weight and the target weight is greater than 0.36 oz.
Lets say the actual weight is 'x'. So,
But there can be times when the actual weight 'x' could be less than 0.36, So the order will be changed:
The absolute value will sum up these two into a single inequality:
Simplifying the inequalities, we get:
(we have added 18.25 on both sides)
Subtracting 18.25 from both the sides we get:
After sign change it is:
So we can see that only or since is the one that represents the scenario given above.
Box-and-whisker plots and the five key values used in constructing a box-and-whisker plot. The key values are called a five-number summary, which consists of the minimum, first quartile, median, third quartile, and maximum.
