Answer:
- y = 0.937976x +12.765
- $12,765
- $31,524
- the cost increase each year
Step-by-step explanation:
1. For this sort of question a graphing calculator or spreadsheet are suitable tools. The attached shows the linear regression line to have the equation ...
... y = 0.937976x + 12.765
where x is years since 2000, and y is average tuition cost in thousands.
2. The y-intercept is the year-2000 tuition: $12,765.
3. Evaluating the formula for x=20 gives y ≈ 31.524, so the year-2020 tuition is expected to be $31,524.
4. The slope is the rate of change of tuition with respect to number of years. It is the average increase per year (in thousands). It amounts to about $938 per year.

Answer:
I know this is a bit late but it is 6 and 12
Step-by-step explanation:
if we use the formula b1 + b2 x h/ 2, u would do inverse operations. you multiply 2 on each side so that 72 would equal b1+b2xh and divide height on each side to get 18 is b1 + b2. if b1 is 2 times, it would be 2x + x is 3x and divide 3 on each side would give you 6 for x. If 6 is x, one side would be 6 and the other would be 12
Answer:
y = |x - 5| + 4
Step-by-step explanation:
Because the graph is shifted up 4 units, that means the equation of the graph is:
y = |x| + 4
Because you are moving it 5 units to the right, the new equation is:
y = |x - 5| + 4
