Answer:

[tex]-3.5[/tex]

Step-by-step explanation:

[tex](a-2b)^{3} \\=a^{3}-6a^{2} b+6ab^{2}-8b^{3}[/tex]

Given that,

[tex]a=(-3)\\b=(-1/2)[/tex]

So,

[tex](a-2b)^{3} \\=a^{3}-6a^{2} b+6ab^{2}-8b^{3}\\=(-3)^{3}-6* (-3)^{2} *\frac{-1}{2} +6*(-3)*(\frac{-1}{2} )^{2} -8*(\frac{-1}{2} )^{3} \\= (-27)-6*9*\frac{-1}{2} +-18*\frac{1}{4} -8*\frac{-1}{8} \\=(-27)-6*-4.5-4.5+1\\=-27+27-4.5+1\\=-3.5[/tex]

Answer:

Step-by-step explanation:

1/20 hour = 5 minutes

(We can now call 1/20 of an hour 5 minutes)

If it falls 4/50 of a mile in 5 minutes (1/20 of an hour),

we do 4/50 * 12 because there are 12 5-minute intervals in an hour/

4/50 * 12 = 48/50 = 24/25 of a mile

Therefore, the raindrop will travel 24/25 of a mile in an hour.

The distance of the raindrop in an hour will be 24/25 miles.

The speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Speed is a scalar quantity and is described by its magnitude only.

Given that A raindrop falls at a rate of 4/50 mile in 1/20 hour. The distance in an hour will be calculated as:-

If it falls 4/50 of a mile in 5 minutes ( 1/20 of an hour ),

Distance = 4/50 x 12

Distance = 4/50 x 12

Distance = 48/50

Distance = 24/25 of a mile

Therefore, the distance of the raindrop in an hour will be 24/25 miles.

Answer:

the slope: 2

Equation : y=2x-4

Answer:

-2

Step-by-step explanation:

use the rise over run equation: your rise is 8 and your run is -4

your first y is 4 and your second y is -4: 4 - (-4) is 8

your first x is -4 and you second x is 0; -4 - 0 is -4

dividing 8 by -4 will give you -2, which is your slope

Answer:

Victor has 18 trophies

Step-by-step explanation:

Let's set up "let statements"

Let d = Dean's trophies

Since Victor has 2 times as many trophies as Dean, we can set up a let statement for Victor like this...

Let 2d = Victor's trophies

Now we can set up an equation! Since we know Dean and Victor have 27 trophies altogether...our equation has to involve addition...

2d + d = 27

Combine like terms...(2d and d)

3d = 27

Divide 3 on both sides to isolate the variable "d"

3d ÷ 3 = d

27 ÷ 3 = 9

So...

d = 9

That means Dean has 9 trophies. But we are not done yet because we need to figure out how many trophies Victor has. Since Victor has 2 times the number of trophies as Dean we can do...

2 · 9 = 18

Therefore, Victor has 18 trophies!

Answer:

y = -5/2x + -4 (or) y = -5/2x - 4

Step-by-step explanation:

Your slope is -5/2, so all you have to do is take the point (-2, 1) and use the slope to find a second point of (0, -4) which is coincidentally the y-intercept. Then you just plug the data into the equation y = mx+b. You do that and you get the answer of y = -5/2x+-4

Answer: -14.5

What I did was Subtract 3.5 from -11.

When you add them together, you get 14.5, but 14.5 isn't correct, as that's a very large number compared to -11.

Answer:

-14.5

Step-by-step explanation:

-11 - 3.5

Because 11 is already negative, when you subtract a number from a negative, think of -11 becoming "smaller" (smaller being -14, or -25).

When doing -11 - 3.5, think if it as adding 11 and 3.5 together !

When you add them together, you get 14.5, but 14.5 isn't correct, as that's a very large number compared to -11.

You add a negative sign to said -14.5, and that's your answer !

Subtracting from a negative is confusing, so I taught myself to think of it as adding the numbers as if they were positive and adding a negative sign !
