X/35 = 7
we can multiply 35 on both sides
x = 245
Answer:
13
Step-by-step explanation:
f(x) = x/2 +8
f(10) = 10/2 +8
f(10) = 5+8
f(10) = 13
A relation is a function if it passes the vertical line test. That graph in a coordinate plane is just a sin wave that is spread out. If you run a perfectly vertical line through the graph at every place on the graph, the line you draw will only go through the graph at one place every time. That makes it a function. It's not a one-to-one function cuz it fails the horizontal line test, but it is a function!
For number 2 problem:
10x=5y
15x=7.5y
20x=10y
For problem3:
3x=1.5y
4x=2y
5x=2.5y
