Answer:
negative correlation on Edg
Step-by-step explanation:
Answer:
x=9 y=-4
Step-by-step explanation:
1) to eliminate a variable make sure they are the same so you can cancel them out
lets eliminate x
-3 and -2 share a GCF of 6 so
2(-3x-4y=-11)
-6x-8y=-22
3(-2x-6y=6)
-6x-18y=18
-6x-8y=-22
-
-6x-18y=18
--------------------------
10y=-40
y=-4
2)substitute y as -4 in the second equation
-2x-6(-4)=6
-2x+24=6
-2x=-18
x=9
The answer is (2-3)-(4+1)
Answer:
It will take 12 games
Step-by-step explanation:
We can use ratio's to solve this problem. Put the points over the number of games
30 points 45 points
------------ = ----------------
8 games x games
Using cross products
30x = 8*45
Divide each side by 30
30x/30 = 8*45/30
x =12
Answer:
46.37 square units
Step-by-step explanation:
If the right triangle is revolved the figure shown about the y-axis completely, the figure will be formed as a cone. As you can see in my attached photo.
So, the radius of the cone is : 2 units
the slant height is: = (use pytagon theory)
Hence, the total surface area of the resulting figure
SA = π * the radius * the slant height + π*
= 3.14*2* + 3.14*2*2
= 33.81 + 12.56
=46.37 square units
