Answer:</h3><h3>D</h3><h3 /><h3>
Step-by-step explanation:</h3><h3>
</h3><h3>In a function, an input (x) value should have only one output (y) value.</h3><h3 />
-------------------------------------------------------------------------------------------
<em>Example: (View attached image below). </em><em>Table A</em><em> is a function because each </em><em>x </em><em>value has only 1 </em><em>y</em><em> value. But </em><em>Table B</em><em> is not a function because the </em><em>x value</em><em> of </em><em>4 </em><em>has </em><em>2 y values</em><em>.</em>
Answer: I saw on another post on here with the same question that someone said it was
B. The sum of the volumes of X and Z equals the volume of Y.
80% × x = 32
.80x = 32
x = 32/.8
x = 40
Setup: 4x-6=3x+4
<span>4x=3x+10 </span>
<span>1x=10 </span>
x = 10
