x≤99
the explanation is that
81+19=100
this being true, x can't be greater than 100
Graph is attached
I hope this Helps!

17.
19.
To find:
The values of the given logarithms by using the properties of logarithms.
Solution:
15. We have,
Using property of logarithms, we get
Therefore, the value of is 1.
17. We have,
Using properties of logarithms, we get
Therefore, the value of is -1.
19. We have,
Using property of logarithms, we get
Therefore, the value of is 100.
Answer:
1. RQ
2. R, Y and V
3. T
4. No
Step-by-step explanation:
If we imagine a plane as a rectangle, we can easily see that planes RSTQ and RVUQ intersect in line RQ. Basically, if two planes intersect each other, that intersection is always a line.
Collinear points lie on the same line. Every two points make a line, so the third one also needs to lie along that line. On the diagram, R, Y and V are the only three points on the same line.
From the diagram, we can infer that QT and TX intersect in point T. Additionally, every two lines intersect in a point (of course, unless they're parallel).
Coplanar points lie in the same plane. Three points are enough to define a plane. Whichever three points (R, Q, W and U) we choose we'll have a plane, but the fourth point won't lie in it. This means they are not coplanar.
