I think it’s Quadrant III
Hey there! I'm happy to help!
We have 5 test scores that give us an average of at least 75.
76, 85, 92, 63, x
We add these all up and divide by 5 to get 75.
Let's go backwards to find x.
We multiply by 5.
75(5)=375
We subtract all of the numbers except for x.
375-76-85-92-63=59
So, you need to earn at least 59 on the next test to achieve an average of at least 75.
Have a wonderful day! :D
The points (1,-2) and (4,16) are not in the line but the point (-3,-18) is on the line. (Work is shown in the image)
Answer:
Solving equation i and ii, we get;
3x-3y+x+3y=9+12
4x=21
x=21/4
Putting the value of x in equation ii.
(21/4)+3y=12
3y=12-(21/4)
3y=(48-21/4)
y=27/(4*3)
y=9/4
Answer:
-4 to -1.5
Step-by-step explanation:
When the graph start to slope downwards or go down its decreasing. So when the hump starts to go down at (-4,0) it then starts to go up again after (-1.5,0). Hope this helps:)
