X ·( x + 1 ) = 600
x² + x = 600
x² + x - 600 = 0
x = ( - 1 - 49 ) / 2 = - 50 : 2 = - 25
x = - 25, x + 1 = - 24
( - 25 ) · ( - 24 ) = 600
Answer:
C ) - 25
Answer:
Here x² + z² ≤ 49 which describes the set of all points whose distance from the y-axis is at most 7 .Thus, the inequality represents the region consisting of all points on or inside a circular cylinder of radius 7 with axis the Y-axis
Step-by-step explanation:
The equation given is equivalent to . This square root, by the pythagorean theorem, represents the distance of a point (x,y,z) to the y axis( that is, to the point (0,y,0) ). There are no constraints in y, so for a fixed value of y, these points lie inside the plane of height y and inside the circle of radius 7 centered at (0,y,0). Taking y as a variable, we join all of these circles alongside the y- axis and obtain a cylinder of radius 7.
3) The only points on grid are (4, 4) and (6, 8). The latter point has scale factors of (6/4, 8/4) = (1.5, 2), corresponding to selection B.
4) Reflection across the y-axis uses the rule (x, y) → (-x, y), corresponding to selection B.
5) The question is ambiguous regarding whether the graph is of the original figure or its image. If we assume it is the original figure, the quadrant that is clockwise from quadrant II is quadrant I, corresponding to selection A.
Here is my answer. I hope this is helpful.
