Answer: 1/5
Step-by-step explanation: Because, there is five and you have one chance out of the 5. If that makes any sense.
1 + 129 equals 130 that equals 130
Answer:
x=3, y=4. (3, 4).
Step-by-step explanation:
x+y=7
x+2y=11
--------------
-x-y=-7
x+2y=11
--------------
y=4
x+4=7
x=7-4
x=3
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.
