Answer:
Step-by-step explanation:
The easiest way to solve this equation is to first find and highlight a common factor between two terms. In this case, x^2 can be factored to rewrite the equation as follows:
The (x+7) term can be crossed out on both sides and then for this equation to be true, there are two possibilities:
Either
or
Therefore, the solutions to this equation are -1, 1 or -7.
Answer and explanation:
Temperature:
If it was -5°C, you know that it is very cold and below freezing point (0°C), but if it was 20°C you know the weather is quite warm.
0°C is freezing point and is used as a reference point to be able to tell if the temperature is warm or not.
Answer:
second topmost one
Step-by-step explanation:
a system of parallel lines don't have solutions as they never intersect
Is there supposed to be answer choices?
First you would need to find the median, mode, and range.
60 68 68 71 71 72 75 75 75 83 83 85 87 87 89 90 95 95 98 98
due to no answer choices, I am going to show you the basics of the plot before the 2 scores are added.
