Answer:
the solution set is r>7
step by step:
Subtract 3 from both sides
3−3r−3<−2r−4−3
Simplify
−3r<−2r−7
Add 2r to both sides
−3r+2r<−2r−7+2r
Simplify
−r<−7
Multiply both sides by −1 (reverse the inequality)
(−r)(−1)>(−7)(−1)
Simplify
r>7
Answer:
y = -2
Step-by-step explanation:
See the attached image in the attachment. When x is zero, it intersects the y-axis at y = -2
Yes, it would be A, the slopes are the opposite
The way to work it is to make a table in Excel (or equivalent program) with the data of budget for every year.
This is how it should look:
<span><span><span>year
budget
</span>
<span>

265.1
</span>
<span>

277.5

<span>

Select both columns and inser a scatter plot graph (menu, insert, graph, scatterplot).
Now change the design of the graph to include the model. In this case I got y = 12.724 x + 262.92
x represents the number of year after 1990 and y represents the budget.
Now you can use the model to calcualte the budget when you know the year and to calculate the year when you know the budget.
For year 2001, x = 11 and y = 12.724 (11) + 262. 92 = 402.88 (which is 402,880)
This is the same year for which the budget exceeds 400,000. </span></span></span>
All of my teachers have told me that everyone remembers things best in groups of seven. so I would suggest to pick a continent and start in a corner and spend a couple of days studying seven countries in that area. also quiz your self every once in a while for extra help.
I hope this helps you
