3,4,5 can give you a triangle
Surface area = πr² + πrl
Surface area = π(3)² + π(3)(7) = 94.25 in² (nearest hundredth)
Cross multiply
2(11-x) = 1(3x+2)
Distribute
22-2x = 3x+2
Subtract 22 from both sides
-2x = 3x-20
Subtract 3x from both sides
-5x = -20
Divide both sides by -5
x=4
14 because a negative minus a negative is a positive; you add a line and change the sign
Answer:
Option 2, (y = 4/6x - 4)
Step-by-step explanation:
Knowing that m acts as the slope in general, we can conclude that part of the equation is as such:
y = 4/6x
Now we are given coordinate (0, - 4) so that here x = 0 and y = - 4. Let's substitute these values into the prior equation:
y = 4/6x
-4 = 4/6(0)
-4 = 0
Now in order for y (-4) to be equal to the opposite side of the equation you would have to add -4:
-4 = 0 - 4
-4 = -4
That would mean the equation represents:
y = 4/6x - 4
