======================================================

Explanation:

Double everything in the second equation to go from x-y = 3 to 2x-2y = 6.

So we have this equivalent system of equations

[tex]\begin{cases}4x+2y = 6\\2x-2y=6\end{cases}[/tex]

We can then add straight down. The x terms add to 6x. The y terms go away because they add to 0. The stuff on the right hand sides add to 12.

After those three sets of addition operations, we have the new equation 6x = 12 which solves to x = 2 after dividing both sides by 6.

Now use x = 2 with any of the equations mentioned that have x,y involved so we can solve for y.

4x+2y = 6

4(2)+2y = 6

8+2y = 6

2y = 6-8

2y = -2

y = -2/2

y = -1

or we could say

x-y = 3

2-y = 3

-y = 3-2

-y = 1

y = -1

Either way, we get the same y value.

Since x = 2 and y = -1 pair up together, we get the ordered pair solution (x,y) = (2, -1). Therefore, the answer is choice D.

If you were to graph the two equations, as shown below, the two lines intersect at (2,-1). This point is on both lines at the same time. This is visual confirmation that the point is a solution to both equations. Though you should still algebraically check each original equation.

Answer:

y = -180 + 3x

Step-by-step explanation:

Because AB = AC -> ABC is a isosceles triangle -> B = C

Because AB = BD -> ABD is an isosceles triangle -> A = D -> x = D

We have ADB + ADC = 180 -> x + ADC = 180 -> ADC = 180 - x (1)

We have x = D, and BAD + ADB + ABD = 180 -> ABD = 180 - 2x but B = C -> C = 180 - 2x (2)

With (1) and (2) We have DAC + ACD + ADC = 180

-> y + 180 -2x + 180 -x = 180

-> y + 360 - 3x = 180

-> y = -180 + 3x

Answer:

y=3x-180

Answer:

Question 2: The first function represents the amount of money she'll have from her 450 under her bed.

s(x) = 450

The second function represents the amount of money she'll earn from babysitting per hour (x):

a(x) = 6(x - 2)

To figure the combined amount, we can add the two functions:

f(x) = s(x) + a(x)

f(x) = 450 + 6(x - 2)

From there, she can simplify the function by distributing, then combining the like terms to simplify:

f(x) = 450 + 6x - 12

f(x) = 438 + 6x

Answer:

f(x) = 438 + 6x

Question 4: His functions are;

h(x)=$350

s(x)=(1.04)^x-1

To find total amount of money in Tommy's account using the functions above, we substitute the first equation x=$350 in the second function.

Answer

The difference between the greatest amount of time and the least amount of time spent surfing the Internet is 3 hours.

Explanation

The meaning of range is the difference between the largest and smallest numbers in a set.

In this case, it's possible that one of the students spends no time surfing the internet, and another student spends 3 hours. The range of the data would be 3. It's also possible that some students spend 20 hours surfing the internet, and other students spends 23 hours surfing the internet (although, that's obviously unreasonable).

Answer:

B. The difference between the greatest amount of time and the least amount of time spent surfing the Internet is 3 hours.

Answer:

[tex]2\sqrt{2x}[/tex] or [tex]8x^2[/tex]

Step-by-step explanation:

first you find the distance between P and O which is 4n (use the distance formula -- [tex]\sqrt{\left(x_1-x_2\right)^2+\left(y_1-y_2\right)}[/tex])

then find the distance between O and Q also using the distance formula; it gives you 4n

then find the hypotunuse by using the pythagorean theorem, [tex]a^2+b^2=c^2[/tex] which would be [tex]4n^2+4n^2=hypotenuse[/tex] and when you simplify it, you get [tex]8x^2[/tex] and if you need it in radical form, it would be [tex]2\sqrt{2x}[/tex]

Answer:

[tex]Hypotenuse = 4n \sqrt{2} [/tex]

Step-by-step explanation:

Catethus1=4n

Catethus2=4n

Hypotenuse=?

[tex]Hypotenuse= \sqrt{{(catethus1)}^{2} + {(catethus2)}^{2}} \: = \sqrt{{(4n)}^{2} + {(4n)}^{2}} \: = 4n \sqrt{2} [/tex]

Answer: 17

Step-by-step explanation:

In this problem, the phrase "a number" can be interpreted as a variable.  In this case, let the variable be "x."

Thus, "twice a number" = "2x"

"and 13" = "+ 13"

"is 47" = "= 47"

Thus, the problem is simply 2x + 13 = 47.

Then, simply subtract 13 from both sides to get 2x = 34.

Then, simply divide both sides by 2 to get x = 17.

Because "the number" is "x," the number is 17.

Answer:

  obtuse

Step-by-step explanation:

The law of cosines tells you ...

  b² = a² +c² -2ac·cos(B)

Substituting for a²+c² using the given equation, we have ...

  b² = b²·cos(B)² -2ac·cos(B)

We can subtract b² to get a quadratic in standard form for cos(B).

  b²·cos(B)² -2ac·cos(B) -b² = 0

Solving this using the quadratic formula gives ...

  [tex]\cos(B)=\dfrac{-(-2ac)\pm\sqrt{(-2ac)^2-4(b^2)(-b^2)}}{2b^2}\\\\\cos(B)=\dfrac{ac}{b^2}\pm\sqrt{\left(\dfrac{ac}{b^2}\right)^2+1}[/tex]

The fraction ac/b² is always positive, so the term on the right (the square root) is always greater than 1. The value of cos(B) cannot be greater than 1, so the only viable value for cos(B) is ...

  [tex]\cos(B)=\dfrac{ac}{b^2}-\sqrt{\left(\dfrac{ac}{b^2}\right)^2+1}[/tex]

The value of the radical is necessarily greater than ac/b², so cos(B) is necessarily negative. When cos(B) < 0, B > 90°. The triangle is obtuse.
