in step 2 he made his first mistake
1/2(n-4)-3=3-(2n+3)
1/2n-4/2-3=3-(2n+3)
1/2n-2-3=3-(2n+3)
in the second step he put 5 instead of 2.
I’m not entirely sure, but I think that if the y-value is not included, it should equal 0.
The answer would be- How many hours do you spend at the pharmacy each month?
This is the answer because it can be found by using data!
Answer:
y = (1/3)x +4
Step-by-step explanation:
The line intercepts the y-axis at y=4. It has a "rise" of 1 unit for each "run" of 3 units, so its slope is rise/run = 1/3.
The slope-intercept form of the equation of a line is ...
y = mx + b . . . . . where m is the slope and b is the y-intercept.
When we put the proper numbers in the equation, we have ...
y = (1/3)x + 4
Answer:
Step-by-step explanation:
![y=\frac{x}{x+4}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7Bx%7D%7Bx%2B4%7D)
for domain x+4≠0
x≠-4
domain={R-{-4}}
R=all real numbers.
y(x+4)=x
yx+4y=x
yx-x=-4y
x(y-1)=-4y
![x=-\frac{4y}{y+1} \\y+1\neq 0\\y\neq -1\\](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7B4y%7D%7By%2B1%7D%20%5C%5Cy%2B1%5Cneq%200%5C%5Cy%5Cneq%20-1%5C%5C)
so Range ={R-{-1}}
