Answer:

true

Step-by-step explanation:

22 divided my 2 is 11

Answer:

22 divided by 2 is 11

Step-by-step explanation:

Answer:

5x + 6y = 20_____(1)

8x - 6y = -46_____(2)

Solving simultaneously:

Eqn(1) + Eqn(2)

5x + 8x + 6y + (-6y) = 20 + (-46)

13x = -26

x = -2

substituting this into Eqn (1):

5(-2) + 6y = 20

-10 + 6y = 20

6y = 30

y = 5

hence:

x = -2,y = 5.

A linear proportional relationship is shown by y = 3x - 7.

We know that when we talk about a linear relationship, we mean the kind of relationship that would obey the equation of the straight line and the equation of the straight line would be y = mx + c

We have to look at the representations and see the one that actually fits into the model that have been shown above and when we look at it we can see that the y = 3x - 7.

This follows the pattern of the equation of the straight line.

The best representation of a linear proportional relationship is the table of values

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

The list of options

As a general rule, the equation of a linear proportional relationship is represented as

y = kx

Where k is the constant of proportion

This means that the given equations are not proportional relationship because they do not have the form y = kx

i.e. y = 3x - 7 and y = 8x + 25 do not have the form y = kx

Also, the equation y = kx implies that the graph passes through the origin

So, the given graph is not

The equation of the table is represented as

y = Y/X * x

So, we have

y = 2/24 * x

This gives

y = x/12

The equation of the table is of the form y = kx

Hence, the solution is the table of values

Answer:

x=409

Step-by-step explanation:

First add and make the varible on one side of the equation: add 15 to both sides. 5x=2045

Then divide to find x. 2045/5=409

Answer:

Step-by-step explanation:

In this example predicted value is 87 and actual value is 100

Error is 100 - 87 = 13

Absolute error is same, |100 - 87| = 13

So the correct choice is the last one:

Step-by-step explanation:

⇒ they are asking to find  reciprocal

⇒ 10+3/5

  13/5

⇔now, the reciprocal of 13/5 is

= 5/13

Step-by-step explanation:

(a) dP/dt = kP (1 − P/L)

L is the carrying capacity (20 billion = 20,000 million).

Since P₀ is small compared to L, we can approximate the initial rate as:

(dP/dt)₀ ≈ kP₀

Using the maximum birth rate and death rate, the initial growth rate is 40 mil/year − 20 mil/year = 20 mil/year.

20 = k (6,100)

k = 1/305

dP/dt = 1/305 P (1 − (P/20,000))

(b) P(t) = 20,000 / (1 + Ce^(-t/305))

6,100 = 20,000 / (1 + C)

C = 2.279

P(t) = 20,000 / (1 + 2.279e^(-t/305))

P(10) = 20,000 / (1 + 2.279e^(-10/305))

P(10) = 6240 million

P(10) = 6.24 billion

This is less than the actual population of 6.9 billion.

(c) P(100) = 20,000 / (1 + 2.279e^(-100/305))

P(100) = 7570 million = 7.57 billion

P(600) = 20,000 / (1 + 2.279e^(-600/305))

P(600) = 15170 million = 15.17 billion

Answer:

The correct option is 'No Solution'.

Step-by-step explanation:

Given the system of the equations

[tex]y=\frac{1}{2}x-1[/tex]

[tex]2x-4y=12[/tex]

solving the system of the equations

[tex]\begin{bmatrix}y=\frac{1}{2}x-1\\ 2x-4y=12\end{bmatrix}[/tex]

[tex]\mathrm{Subsititute\:}y=\frac{1}{2}x-1[/tex]

[tex]\begin{bmatrix}2x-4\left(\frac{1}{2}x-1\right)=12\end{bmatrix}[/tex]

[tex]2x-4\left(\frac{1}{2}x-1\right)=12[/tex]

[tex]2x-2x+4=12[/tex]

[tex]4=12[/tex]

as

4=12 is false, therefore the system of equations has no solution.

Therefore, the correct option is 'No Solution'.
