Answer:
y = + 4
Step-by-step explanation:
y² - x = 7 ← substitute x = 9 into the equation
y² - 9 = 7 ( add 9 to both sides )
y² = 16 ( take square root of both sides )
y = ± 
= ± 4
the positive value of y when x = 9 is + 4

Answer:
Parallel lines are lines <u>in the same plane</u> that do not intersect, like lines on notebook paper.
The "in the same plane" requirement is important! Take a look at the attached image. Lines AD and DC don't intersect, but they are <u>not</u> in the same plane (face of the rectangular solid). We don't call those parallel, we call them skew lines.
<span><u><em>The correct answers are:</em></u>
A, B and C.
<u><em>Explanation</em></u><span><u><em>: </em></u>
<u>A parallelogram</u> is a quadrilateral with both pairs of opposite sides parallel.
<u>A rectangle</u> is a parallelogram with all right angles, so yes, every rectangle is a parallelogram.
<u>A square</u> is a parallelogram with all right angles and all congruent sides; since it is a parallelogram with all right angles, every square is a rectangle.
<u>A rhombus</u> is a parallelogram with all congruent sides.
Since a square is a parallelogram with all congruent sides, then every square is a rhombus.
<u>A </u><u>trapezoid</u> is a quadrilateral with one pair of parallel sides. Since a rhombus is a parallelogram, with 2 pairs of parallel sides, rhombus are not trapezoids.</span></span>
