Answer:
z = 7.5
Step-by-step explanation:
Given that z is directly proportional to x and inversely proportional to y then the equation relating them is
z = ← k is the constant of proportionality
To find k use the condition when x = 16, y = 5, z = 16, then
k = = = 5
z = ← equation of proportionality
When x = 21, y = 14, then
z = = 7.5
Answer:
not sure
Step-by-step explanation:
The only answers you can really use is the first and fifth ones.
The second one is not true because the point do not look random. they look like they might be a parabola
The third one is not a choice because plot does not have a linear (straight line) pattern. Linear means straight line.
The fourth one is not true. There is only 1 point below the x axis. The rest are above the x axis.
The 5th one is true.
The 6th one is not true. Those points do not have a straight line pattern.
Since XY is the perpendicular bisector of JK, and when we say perpendicular, it is a line which cuts a line segment into two equal parts at 90°. So the statements that must be true about it would be all of the above: XY and JK form four right angles, P is the midpoint of XY, m D. XP=YP, JP=KP and XY perpendicular to JK. Hope this answer helps.
