4x is the proportionality
B 11.2 Have a good day :)
All linear functions have in common...
1. Their highest exponent is 1.
2. The graphs of the equations are lines.
When finding things in common between different types of functions, you always have to look at the two sides of math; geometry and algebra. Geometry is all the graphs, and algebra is the equations.
I hope this helps!
Answer:
4/45
Step-by-step explanation:
First find all the pairs that make 9 that are two digit:
1+8
2+7
3+6
4+5
5+4
3+6
2+7
1+8
That's 8 pairs, and as there are 90 two digit numbers, 8/90 is the answer. but if you want to simplify, the answer is 4/45
C, there are 32 more students who want a beef meal than want a chicken meal.
200/25 = 8
12 x 8 = 96
8 x 8 = 64
5 x 8 = 40
& 96 - 64 = 32
