what is the the highest common factor of -15x^2 -20x

That is a difficult one

Assuming A, B and C are all on the same straight line, this means,

AB+BC = AC

through the segment addition postulate.

So,

AC = AB+BC

AC = (6x+2)+(5x+3)

AC = 6x+2+5x+3

AC = (6x+5x)+(2+3)

Answer:

n=-3

Step-by-step explanation:

so its actually 3n+9=0 so you can subtract 9 to get 3n=-9

                            -9  -9

then divide 3n and -9 by 3 to get n by itself so it looks like n=-3 hope this helps :)

Answer:

16, 16, 32, 32

Step-by-step explanation: If you take 92 and divide it by 4 you get 24 but you need one side to be longer than the other, subtract 6 and you get 16, and 16x2 is 32, if you add 16+16+32+32 you get 96.

Answer:

D = 4.2

Step-by-step explanation:

-5.5 ( d - 2 ) = - 12.1

-5.5d + 11 = - 12.1

11 + 12.1 = 5.5d

23.1 = 5.5d

d = 23.1 ÷ 5.5

d = 4.2

Answer:

When you multiply two numbers or variables with the same base, you simply add the exponents. When you multiply expressions with the same exponent but different bases, you multiply the bases and use the same exponent.

Answer:

1) [tex]\frac{dy}{dx}=12x^2+6x-6[/tex]

2) [tex]x\leq-1\text{ or } x\geq 1/2[/tex]

Step-by-step explanation:

So we have the equation:

[tex]y=4x^3+3x^2-6x-1[/tex]

Part A)

We want to find the derivative of the above function. So:

[tex]\frac{dy}{dx}=\frac{d}{dx}[4x^3+3x^2-6x-1][/tex]

Expand:

[tex]\frac{dy}{dx}=\frac{d}{dx}[4x^3]+\frac{d}{dx}[3x^2]+\frac{d}{dx}[-6x]+\frac{d}{dx}[-1][/tex]

Use the power rule. Therefore, our derivative is:

[tex]\frac{dy}{dx}=3(4x^2)+2(3x)+(-6)+(0)[/tex]

Simplify:

[tex]\frac{dy}{dx}=12x^2+6x-6[/tex]

Part B)

We want to find the range of the values of x such that:

[tex]\frac{dy}{dx}\geq 0[/tex]

So, all we have to do is substitute our derivative in:

[tex]12x^2+6x-6\geq0[/tex]

And solve for this quadratic inequality!

Solve it normally. Pretend the inequality is with an equal sign. So:

[tex]12x^2+6x-6=0[/tex]

Divide everything by 6:

[tex]2x^2+x-1=0[/tex]

Factor. We can use -2 and 1. So:

[tex]2x^2+2x-x-1=0[/tex]

From the first two terms, factor out 2x.

From the third and fourth terms, factor out a negative. So:

[tex]2x(x+1)-(x+1)=0[/tex]

Grouping:

[tex](2x-1)(x+1)=0[/tex]

Zero Product Property:

[tex]2x-1=0\text{ or } x+1=0[/tex]

Solve for x in each case:

[tex]x=1/2\text{ or } x=-1[/tex]

So, the zeros of our function is -1 and 1/2.

Looking above, we can see that this is a greater than inequality.

Since this is a greater than inequality, our solution is all values to the left of the first zero and all values to the right of the second zero.

Therefore, our solution is:

[tex]x\leq-1\text{ or } x\geq 1/2[/tex]

In interval notation, this is:

[tex](-\infty,-1]\cup[1/2,\infty)[/tex]

So, for all values within the above interval, our derivative, dy/dx, will be greater than or equal to 0.

And we're done!

3.) How much money would you earn in three months (assume 4 weeks in each month) at each of the jobs you listed in #2 if you worked 6 hours per day for 5 days each week?

-------------------------------------

1. dog walking:

6 hr/day (5 day) x (4 weeks x 3 months) x $30/hour

$10,800 in 3 months

-------------------------------------

2.  private swim instructor

6 hr/day (5 day) x (4 weeks x 3 months) x $20/hour

$7,200 in 3 months

-------------------------------------

3.  sandwich maker

6 hr/day (5 day) x (4 weeks x 3 months) x $16.75/hour

According to the first scale, 2 red balls = 1 star.

According to the second scale, 2 triangles = 1 star

So,

1 triangle = 1 red ball

1 star = 2 red balls

1 red ball = 1 red ball

Therefore, 2 + 1 + 1 = 4 red balls

The last scale needs 4 red balls

Answer:

0.2

Step-by-step explanation:

0.002 x 10 as it is 1/10 of the size

The answer is 0.2.

Here,

We have to find the number as 'the answer to 0.02 is 1/10 of the number.'

What is Mathematical expression?

The combination of numbers and variables by using operations addition, subtraction, multiplication and division is called Mathematical expression.

Now,

Let the number is x.

Then, By given condition the expression is written as;

0.02 = (1/10) * x

(1/10) * x = 0.02

x = 0.02 * 10

x = 0.2

Hence, The value is 0.2
