21.5, just took the test!!!!
Answer: 10 minutes
Step-by-step explanation:
First you have to find out how big the tank is. You will have to you the formula Length x Width x Height. 20 x 18 x 10= 3,600 in. Then you would divide that by 360. 3,600/360= 10. It would have to take 10 minutes to empty the aquarium.
The answer i x=4/99 (fraction form )
Answer:
y= -4x+16, (4,0), (0, 8)
Step-by-step explanation:
Let us rewrite the equation in slope intercept form, y=mx+b, where m is the slope:
2y= -8x+16
y= -4x+16
Therefore, -4 is the slope.
The x intercept can be found if we substitute 0 into the y:
0= -4x+16
4x=16
x=4
(4,0)
The y intercept can be found if we substitute 0 into the x:
2y= -8*0 +16
2y=0+16
2y=16
y=8
(0,8)

Step-by-step explanation:
16x2 + 4y2 + 9z2 – 16xy + 12yz – 24zx
(-4x)²+(2y)²+(3z)²+2(-4x)(2y)+2(2y)(3z)+2(-4x)(3z)
So,
(-4x+2y+3z)²
or
(-4x+2y+3z).(-4x+2y+3z)
