8260 line over 6
Step-by-step explanation:
Answer:
Step-by-step explanation:
A linear equation in two variables doesn't involve any power higher than one for either variable. It has the general form Ax + By + C = 0, where A, B and C are constants. ... A quadratic equation, on the other hand, involves one of the variables raised to the second power. It has the general form y = ax2 + bx + c
Answer:
A.
Step-by-step explanation:
Graph B must be incorrect as this is a directly proportional relationship. Likewise, graph C shows an inversely proportional relationship.
Between graph A and D, only graph A passes through the origin, which is true because if length is zero, perimeter is zero.
Hence the answer is Graph A.
The formula of a distance between two points A and B is :
You should this formula by heart.
Then, you just have to apply it ! :D
Here :
Therefore :
In short, the answer would be the first option :
.
Hope this helps !

Remember, |n|≥0 for all real numbers n
so
-|x|=0
times -1
|x|=0
true, x=0, has a solution
|x|=-15
false, can't have negative absolute value
-|x|=12
|x|=-12
false, no negative absolute value
-|-x|=9
|-x|=-9
false, no negative absolute value
-|-x|=-2
|-x|=2
x=2 or -2
true, has solutions
the ones that have no solutions are
|x|=-15
-|x|=12
-|-x|=9
