Answer:
10x-20 uhhh yeah that's the answer
Answer:
Step-by-step explanation:
They are both straight lines. Function A has slope -5
Function B has slope -4.5
-4.5 > -5
B has the greater rate of change.
Answer: 
=========================================================
Explanation:
Use the pythagorean trig identity
and plug in the fact that 
Isolating sine leads to
. I'm skipping the steps here, but let me know if you need to see them.
The result is negative because we're in quadrant 4, when y < 0 so it's when sine is negative.
Therefore,

The answer is B.
Slope is 3; point (2,7)
7=3(2)+B
7=6+B
1=B
M=3
y=3x+1 slope intercept form
3x -y = -1 standard form
Answer:
option: C is correct.
Step-by-step explanation:
since, we are given a parent function f(x) as: f(x)=x.
We are asked to find what change will occur in the function when the parent function f(x) is replaced by f(9x).
let g(x) be the function formed by replacing f(x) with f(9x) i.e.
g(x)=f(9x)=9x.
clearly the slope of the function g(x)=f(9x) is 9. ( since on comparing the equation with the slope intercept form y=mx+c; where m is the slope of the line and c is the y- intercept).
whereas the slope of the function f(x)=x is 1.
Hence there is an increment of slope by a factor of 9.
Hence, option C is correct.
