Given that this is based on simple interest, in the first case, investing at 4% for 3 years gives a total interest of 4%*3 = 12%. In the second case, investing at 6% for 4 years gives a total interest of 6%*4 years = 24%. (We can do this since the same principal is given to both.) This is exactly double that of the first case of 12%, so the second choice is the right answer.

How can you solve x-8y=40?
OLga [1]
Simplifying
x + -8y = 40

Solving
x + -8y = 40

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '8y' to each side of the equation.
x + -8y + 8y = 40 + 8y

Combine like terms: -8y + 8y = 0
x + 0 = 40 + 8y
x = 40 + 8y

Simplifying
x = 40 + 8y

If y varies directly with x, Write an equation relating x and y when y = -30 and x = 6.
ziro4ka [17]

Answer:

y=-5x

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

so

For x=6,y=-30

substitute

y/x=k------> k=-30/6=-5

therefore

y=-5x

A rollercoasterbrises 210 feet into the air, drops 240 feet, rises 80 feet before dropping another 30 feet again. Finally the ro
professor190 [17]

Answer:

-30 feet

Step-by-step explanation:

What we know:

The rollercoaster first rose 210 feet, so after rise 1, the height is +210 feet.

After that, it dropped 240 feet. This is greater than the 210 feet it initially rose, so the number is now negative. The height is now -30 feet.

210 - 240 = -|240-210| = -|30| = -30 feet

After that, it rose another 80 feet. That outdoes the eariler -30 feet, so we're back to a positive height. After that rise, the height is now +50 feet.

-30 + 80 = |80 - 30| = |50| = 50 feet

Then the last two drops combine for a 80-foot drop. This is greater than the +50-foot height it was at, so we're back at -30 feet.

50 - 80 -|80 - 50| = -|30| = -30 feet after the last drop
