The answer is 13.5<<<<<<<<<<<<<<<<
Step-by-step explanation:
x. y=3x². y=3^x
0. 0. 1
1. <u>3</u><u> </u> <u>3</u><u> </u>
2. <u>12</u><u>. </u> <u>9</u><u>.</u>
hope this helps you. Just put the value of x in the equations of y.
Answer:
6 weeks
Step-by-step explanation:
You need to write an equation for each.
For Andre, he has 100 dollars, and every week gets 5 dollars more. You add the 5 dollars, and Since you don't know how many weeks it has been, use a variable.
For Elena, she has 10 dollars, and gets 20 each week.
Now that you know that it has been 4 weeks, you can plug in 4 for the variable for weeks.
Andrew:100+5(4)=100+20+120
Elena: 10+20(4)=10+80=90
Andrew has more money in this time.
To find when they have the same amount, equal their expressions to each other. This means that they will have the same amount (because they are equalled) and you can solve to find the variable, which means the weeks that they are equal at.
Bring the like terms to each side by canceling them out. Since you have positive 10, then subtract 10 to each side. You have 5w, so subtract 5w to each side.
100+5w=10+20w
90+5w=20w
90=15w
90 divided by 15=6
w=6
Step 1) Plot the points (you do know how to plot, do you?)
Step 2) Take that point and move it 8 squares to left then 9 down
Step 3) You should get (-3,-4). If you didn't let me know. :)
Step 4) ABout how many units are they away from each other?
Step 5) Hint: add the units you needed to move.
Hope this helps. Let me know if it didn't. :)
Answer:
11. always
12. always
13. always
14. never

18. sometimes
19. sometimes
20. never
Step-by-step explanation:
11. A line can be defined by at least two points
12. A plane can be defined by at least three points
13. If two planes intersect, then they form a line at the intersection.
14. If two lines intersect, then they form a point at the intersection (not a segment).
15. A line does not have any endpoints (infinite in both ways).
16. If two planes are not parallel they will always intersect.
17. If two lines are not parallel they will always intersect.
18. Two points are sometimes collinear. It depends on where they are.
19. Two points are sometimes coplanar. It depends on where they are.
20. Ray MN and NM are not the same ray because the end points are different.
