Answer:

n = -31.5

Step-by-step explanation:

let 'n' = the number

n/-1.5 = 21

to solve for 'n', multiply each side by -1.5 to get:

n = -31.5

Answer:

b.

Step-by-step explanation:

po dahil 66 ang 0 to 10 or c

Answer:

The equation of a line is written in the form y=mx+b. “m” is the slope and “b” is the y-intercept. With the given slope, the equation so far is y=-4x+b. To find the value of b, substitute the given point.

-12=-4(10)+b

-12=-40+b

28=b

So, the equation of the line is y=-4x+28.

By a change of units, we will get that 108 mi/h = 158.4 ft/s

Here we want to transform 108 mi/h to feet per second.

Then we will use two relations:

Then we can just transform as:

108mi/h = (108*5,280 ft)/h = 570,240 ft/h

570,240 ft/h = 570,240 ft/(3,600 s) = 158.4 ft/s

So we have:

108 mi/h = 158.4 ft/s

Answer:

9000 grams

Step-by-step explanation:

1 kilogram = 1000grams

9 kilograms = 9000 grams

Answer: d) 19.8 pounds

Step-by-step explanation:  (1000)(9 kilograms) = 9000 grams. And yes 9 kilograms does equal to 9000 grams but that isn't the correct answer. Also kilograms isn't equal to b) 9000 ounces, and c) 19.8 ounces even though ounces are apart of the household measurement system because 9 kilograms is equal to 317.466 ounces. (35.274)(9 kilograms) = 317.466 ounces. So the obviously only correct answer is d) 19.8 pounds because 9 kilograms is equal to 19.8 pounds. (2.205)(9 kilograms) = 19.8416 pounds.

The opposite of a positive number is a negative of the same number. The opposite of a negative is the positive of the same number:

0 is neither positive or negative so the opposite of 0 would be 0

0.005 = -0.005

Hello there.

First, assume the numbers [tex]x,~y[/tex] such that they satisties both affirmations:

With these informations, we can set the following equations:

[tex]\begin{center}\align x^2+y^2=8\\ x\cdot y=4\\\end{center}[/tex]

Multiply both sides of the second equation by a factor of [tex]2[/tex]:

[tex]2\cdot x\cdot y = 2\cdot 4\\\\\\ 2xy=8~~~~~(2)^{\ast}[/tex]

Make [tex](1)-(2)^{\ast}[/tex]

[tex]x^2+y^2-2xy=8-8\\\\\\ x^2-2xy+y^2=0[/tex]

We can rewrite the expression on the left hand side using the binomial expansion in reverse: [tex](a-b)^2=a^2-2ab+b^2[/tex], such that:

[tex](x-y)^2=0[/tex]

The square of a number is equal to [tex]0[/tex] if and only if such number is equal to [tex]0[/tex], thus:

[tex]x-y=0\\\\\\ x=y~~~~~~(3)[/tex]

Substituting that information from [tex](3)[/tex] in [tex](2)[/tex], we get:

[tex]x\cdot x = 4\\\\\\ x^2=4[/tex]

Calculate the square root on both sides of the equation:

[tex]\sqrt{x^2}=\sqrt{4}\\\\\\ |x|=2\\\\\\ x=\pm~2[/tex]

Once again with the information in [tex](3)[/tex], we have that:

[tex]y=\pm~2[/tex]

The set of solutions of that satisfies both affirmations is:

[tex]S=\{(x,~y)\in\mathbb{R}^2~|~(x,~y)=(-2,\,-2),~(2,~2)\}[/tex]

This is the set we were looking for.

The polynomial P in lowest degree given the following roots: 4, -3, 4i is x^3 - (4i+1)x^2+4(i-3)x + 48i

Given the roots of a polynomial such as 4, -3, 4i. The equivalent factors of the polynomial will be x-4, x+3 and x-4i

Taking the product of the factors

P(x) = (x-4)(x+3)(x-4i)

P(x) = (x^2+3x-4x-12)(x-4i)

P(x) = (x^2 - x - 12)(x-4i)

P(x) = x^3-4x^2i-x^2+4xi-12x+48i

P(x) = x^3 - (4i+1)x^2+4(i-3)x + 48i

Hence the polynomial P in lowest degree given the following roots: 4, -3, 4i is x^3 - (4i+1)x^2+4(i-3)x + 48i

The points not included in the graph are A: (2.5,3), B: (2.0, 3), C: (3.0, 4) and D: (3.5, 5)

From the question, we have the following parameters that can be used in our computation:

Initial service charge = $2

Additional charges = $1 per hour

This means that the charges after x hours is

f(x) = Initial service charge + Additional charges * x

Substitute the known values in the above equation, so, we have the following representation

f(x) = 2 + x

Using the given points, we have

f(2.5) = 2 + 2.5 = 4.25

f(2.0) = 2 + 2.0 = 4.0

f(3.0) = 2 + 3.0 = 5.0

f(3.5) = 2 + 3.5 = 5.5

This means that all of the points are not in the graph

Answer:

  MN = 56

Step-by-step explanation:

This can only be solved if we know the relation of MN to other dimensions of the trapezoid. If we assume MN is a midline (AM=MD, BN=NC), then MN is the average of the base lengths:

  MN = (AB +CD)/2

  2MN = AB +CD . . . . . multiply by 2

  2(12x -4) = 8x +72 . . . fill in the given values for the segment lengths

  24x -8 = 8x +72 . . . . . eliminate parentheses

  16x = 80 . . . . . . . . . . . add 8-8x
