2.75 as a fraction is 25/100 then you divided which you get 11/4 which is 2 3/4 so 2 3/5 is more hope that helped
Explaination: when graphing a relation, the set of second elements will be the y-values of the graph.
Range: [-4,-3,-2,0,3,5]
Answer:
dont know if its a good answer but
Step-by-step explanation:
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
Interval Notation:

}
The range is the set of all valid
y
values. Use the graph to find the range.

sorry if put wrongly
False.
Let <em>x</em> = -1 and <em>y</em> = 1. Then <em>x</em> + <em>y</em> = 0, so that
|<em>x</em> + <em>y</em>| = |0| = 0
but
|<em>x</em>| = |-1| = 1
|<em>y</em>| = |1| = 1
|<em>x</em>| + |<em>y</em>| = 1 + 1 = 2
I hope this is correct
Simplifying (2x + -1)(x + -3) = 18 Reorder the terms: (-1 + 2x)(x + -3) = 18 Reorder the terms: (-1 + 2x)(-3 + x) = 18 Multiply (-1 + 2x) * (-3 + x) (-1(-3 + x) + 2x * (-3 + x)) = 18 ((-3 * -1 + x * -1) + 2x * (-3 + x)) = 18 ((3 + -1x) + 2x * (-3 + x)) = 18 (3 + -1x + (-3 * 2x + x * 2x)) = 18 (3 + -1x + (-6x + 2x2)) = 18 Combine like terms: -1x + -6x = -7x (3 + -7x + 2x2) = 18 Solving 3 + -7x + 2x2 = 18 Solving for variable 'x'. Reorder the terms: 3 + -18 + -7x + 2x2 = 18 + -18 Combine like terms: 3 + -18 = -15 -15 + -7x + 2x2 = 18 + -18 Combine like terms: 18 + -18 = 0 -15 + -7x + 2x2 = 0 Factor a trinomial. (-3 + -2x)(5 + -1x) = 0
