Answer:

Step-by-step explanation:

As, if we put the value (2,3) in the equation then,

2x + 10y = 20

=> 2(2) + 10(3) = 20

=> 4 + 30 = 20

=> 34 ≠ 20

Hence,

2x+10y=20 does not pass through (2,3)

Answer:

  (c)  a = 14; b = 6√2

Step-by-step explanation:

If you draw a vertical line at the right end of the top segment, it will cut off an isosceles right triangle to its right. That triangle is shown as having a leg length of 6, so the length of 'a' is ...

  a = 8 +6 = 14

The hypotenuse of an isosceles right triangle is √2 times the leg length, so ...

  b = 6√2

Step-by-step explanation:

20% of 40 books is 8.

40-8=32

Again,

1/4 of 40 is 10

Now,

Remaining books =40-(8+10)

=40-18

The Correct choice is D

For the function f(x) = -x+8, f(x-k) = f(x)+k.  Option (D) is correct.

Function is a combination of different types of variable and constants.

A function is denoted by f(x).

The given function is,

f(x) = -x+8,

Substitute x= x+k in the given function,

f(x+k) = -(x+k)+8

f(x+k) = -x-k+8

f(x+k) = -x+8-k

Substitute -x+8= f(x) here,

f(x+k) = f(x)-k

Substitute x= x-k in the given function,

f(x-k) = -(x-k)+8

f(x-k) = -x+k+8

f(x-k) = -x+8+k

Substitute -x+8= f(x) here,

f(x-k) = f(x)+k

Hence, option (D) is correct.

Answer:

F=g^2+6

Step-by-step explanation:

Simplify:

1. Assume you need to multiply the variables by the numbers next to them:

2. Assume the number next to the variables mean exponents:

Let z = 2 - 2√3 i. In polar form, we have

[tex]z = |z| e^{i\arg(z)}[/tex]

where

[tex]|z| = |2-2\sqrt3| = \sqrt{2^2 + (-2\sqrt3)^2} = 4[/tex]

[tex]\arg(z) = \tan^{-1}\left(-\dfrac{2\sqrt3}2\right) = -\tan^{-1}(\sqrt3) = -\dfrac\pi3[/tex]

Equivalently,

[tex]z = 4\left(\cos\left(-\dfrac\pi3\right) + i\sin\left(-\dfrac\pi3\right)\right)[/tex]

Let w be a complex number such that w ² = z. By DeMoivre's theorem,

[tex]z = 4\left(\cos\left(-\dfrac\pi3\right) + i\sin\left(-\dfrac\pi3\right)\right) \\\\ \implies z^{1/2} = 4^{1/2} \left(\cos\left(\dfrac{-\frac\pi3+2k\pi}{2}\right) + i \sin\left(\dfrac{-\frac\pi3+2k\pi}{2}\right)\right)[/tex]

where k ∈ {0, 1}. So the two square roots of z are

[tex]z^{1/2} = \begin{cases}2\left(\cos\left(-\dfrac\pi6\right) + i\sin\left(-\dfrac\pi6\right)\right) & \text{for }k=0 \\\\ 2\left(\cos\left(\dfrac{5\pi}6\right) + i\sin\left(\dfrac{5\pi}6\right)\right) & \text{for }k=1\end{cases}[/tex]

[tex]z^{1/2} = \begin{cases}2\left(\dfrac{\sqrt3}2 - \dfrac12 i\right) & \text{for }k=0 \\\\ 2\left(-\dfrac{\sqrt3}2 + \dfrac12 i\right) & \text{for }k=1\end{cases}[/tex]

[tex]\boxed{z^{1/2} = \begin{cases}\sqrt3 - i & \text{for }k=0 \\ -\sqrt3 + i & \text{for }k=1\end{cases}}[/tex]

Answer:

x = -1

Step-by-step explanation:

5x + 3 -2x = 2(x + 1) >>> Simplify by combining terms

3x + 3 = 2x + 2 >>> Subtract 2x and 3 from both sides

x = -1

months = 10

The total cost becomes the same after 20 months of service, and the total cost is $600.

To find out when the total cost becomes the same for both companies, we need to compare their cumulative costs over time.

Tyson's Ethernet has an activation fee of $100 plus $20 per month, while Darriana's DSL costs $30 per month.

Let's set up equations for both companies:

For Tyson's Ethernet:

Total cost = Activation fee + Monthly charges

Total cost = $100 + ($20/month) * months

For Darriana's DSL:

Total cost = Monthly charges

Total cost = ($30/month) * months

We want to find when these two total costs are equal:

$100 + ($20/month) * months = ($30/month) * months

Now we can solve for the number of months:

$100 + ($20/month) * months = ($30/month) * months

$100 = ($30/month - $20/month) * months

$100 = $10/month * months

months = $100 / $10

months = 10

So, it takes 10 months for the costs to be equal. Now let's find the total cost at that point:

Total cost = ($30/month) * months

Total cost = ($30/month) * 20 months

Total cost = $600

Therefore, after 20 months of service, the total cost is the same for both companies, and the total cost is $600.

Answer:

28

Step-by-step explanation:

The total amount of cows is 48 and is split into 12 groups (7+5).

So 1 group is 48÷12=4

1 group=4

He owns 7 groups of Holstein cows.

So if 1 group is 4, 7 groups is 7x4=28.

28

The number of Holstein cows, if The ratio of Holstein and jersey cows is 7:5, and the Total number of cows is  48, is 28.

It is the contrast of two different quantities. For instance, if your father weighs 90 kg, and you weigh 30 kg, the weight ratio is 1:3. If b is not equal to 0, an ordered pair of numbers a and b, denoted as a / b, is a ratio. A proportion is an equation that equalizes two ratios.

Given:

The ratio of Holstein and jersey cows is 7:5,

Total number of cows = 48

Calculate the values as shown below,

Assume the number of Holstein cows is 7x

7x + 5x = 48

12x = 48

x = 4

Thus, the number of Holstein cows is 7 × 4 = 28

Answer:

piecewise, continuous.

Step-by-step explanation:

This is piecewise simply because it is in pieces. Thus PIECEwise (Pun intended). This is continuous because, as you can see, there is a filled in dot on the same x coordinate as every empty dot. The empty dots mean that that value is not in that part of the graph. However, since the other parts of the function "fill the gaps," then it is continuous.  I hope this helps!
