Answer:

The system of linear equations 8x - 3y = 10 and 16x - 6y = 22 has no solution is correct.

Step-by-step explanation:

1) The system of linear equations 6x - 5y = 8 and 12x - 10y = 16 has no solution.

Solve these linear equations simultaneously

Step 1 : Find y in terms of x from any one equation

6x - 5y = 8

y = 8 - 6x

        -5

Step 2 : Substitute y in terms of x from step 1 in the second equation.

16x - 6y = 22

16x - 6 (8 - 6x) = 22

              -5

80x - 48 + 36x = 22 x -5

94x = 43

x = 0.457

This statement is incorrect as it does have a solution.

2) The system of linear equations 7x + 2y = 6 and 14x + 4y = 16 has an infinite number of solutions.

Solve these linear equations simultaneously

Step 1 : Find y in terms of x from any one equation

7x + 2y = 6

y = 6 - 7x

        2

Step 2 : Substitute y in terms of x from step 1 in the second equation.

14x + 4y = 16

14x + 4(6 - 7x) = 16

              2

14x + 12 - 14x = 16

0 ≠ 4

This statement is not true as there are no solutions.

3) The system of linear equations 8x - 3y = 10 and 16x - 6y = 22 has no solution.

Solve these linear equations simultaneously

Step 1 : Find x in terms of y from any one equation

8x - 3y = 10

x = 10 + 3y

        8

Step 2 : Substitute x in terms of y from step 1 in the second equation.

16x - 6y = 22

16(10 + 3y) - 6y = 22

       8

20 + 6y - 6y = 2

0 ≠ -18

This statement is true because there are no solutions

4) The system of linear equations 9x + 6y = 14 and 18x + 12y = 26 has an infinite number of solutions.

Solve these linear equations simultaneously

Step 1 : Find x in terms of y from any one equation

9x + 6y = 14

x = 14 - 6y

        9

Step 2 : Substitute x in terms of y from step 1 in the second equation.

18x + 12y = 26

18 (14 - 6y) + 12y = 26

        9

8 - 12y + 12y = 26

0 ≠ 18

This statement is incorrect because there are no solutions. It does not have infinite number of solutions.

Answer:

Step-by-step explanation:

The true statement is the third one, because that system of equations has no solutions. This is because those lines are parallel, see image attached.

We can demonstrate this by solving the system:

[tex]\left \{ {{8x-3y=10} \atop {16x-6y=22}} \right.[/tex]

If we multiply the first equation by -2, we would have

[tex]\left \{ {{-16x+6y=-20} \atop {16x-6y=22}} \right\\0x+0y=2\\0=2[/tex]

When this happens, means that the system has no solution, that is, the lines that represents those linear equations, are parallel.

Therefore, the right answer is the third option.

Option 2 - [tex]x^2=3x[/tex]                

Step-by-step explanation:

Given : Susan wants to make 2 square flags to sell at a crafts fair. The fabric she wants to buy is 3 meters wide. she doesn't want any fabric left over.

To find : What's the least amount of fabric she should buy?

Solution :

If  she doesn't want any fabric left over.

The fabric purchased should have same area of the flags.

So, let x be the length of 1 side of the flag.

Area of the flag is

[tex]A=s^2[/tex]

[tex]A=x^2[/tex]

Area of 2 square flags is [tex]A=2x^2[/tex]

Now, Area of fabric is

[tex]A=l\times b[/tex]

[tex]A=x\times 3[/tex]

[tex]A=3x[/tex]

According to question,

Area is same so,

[tex]x^2=3x[/tex]

Therefore, Option 2 is correct.

Answer:

m = -6

Step-by-step explanation:

Put this given equation into slope-intercept form:

y−15=−6(x+7)  becomes y - 15 = -6x - 42.

Adding 15 to both sides results in y = -6x - 27,

and so the slope is -6.  The y-intercept is -27, or (0, -27).

Answer:

slope m = -6

Step-by-step explanation:

y−15=−6(x+7)

y =−6(x+7) + 15

y =−6x +7(-6) + 15

y =−6x -42 + 15

y =−6x - 27

THis is in slope intercept form where slope m = -6

The smallest possible value for the sum of the squares of two numbers differing by 1 is 0.5. This is obtained by setting one number as x and the other as x + 1, and then minimizing the function f(x) = x² + (x + 1)².

The difference of two numbers is 1 implies that if we set one number as x, then the other would be x + 1. To find the smallest possible value for the sum of their squares, you need to minimize the function f(x) = x² + (x + 1)².

Completing the square, this simplifies to 2(x² + 1)². Setting the derivative of this expression, 4x(x² + 1), equal to zero and solving for x, we obtain x = 0 or x = -1. Testing these values within the function f(x), we find that the minimum value is when x = -0.5 and x + 1 = 0.5 and the sum of their squares equals 0.5.

Although one can handle an equation containing an unknown square which produces two solutions, in this problem, the meaningful solution is that the smallest possible value for the sum of their squares is 0.5.

Step-by-step explanation:

Given

7x - 4 = 2x + 11 ( subtract 2x from both sides )

5x - 4 = 11 ( add 4 to both sides )

5x = 15 ( divide both sides by 5 )

x = 3

Answer:

[tex]x=\frac{7}{5}[/tex]

Step-by-step explanation:

The question states product so we know that we're multiplying.

A number and 5, and since the unknown variable is now [tex]x[/tex] we have [tex]5x[/tex] so far.

Then we need to make it so that it is 2 more.

[tex]5x+2[/tex]

Equals 9.

[tex]5x+2=9[/tex]

Solve for the unknown number.

[tex]5x=7[/tex]

[tex]x=\frac{7}{5}[/tex]

Transforming the problem into the equation 5x + 2 = 9, where 'x' is the unknown number, we solve for 'x' by subtracting 2 from both sides and then dividing by 5, yielding 'x' = 7/5, or 1.4.

The mathematics problem described can be solved using simple algebra. The problem is stated as: two more than the product of a number and 5 equals 9. If we use the variable 'x' to represent the unknown number, then we can write the algebraic equation to represent this problem as 5x + 2 = 9. The next step would be to solve this equation to find the value of 'x'. In order to isolate 'x', you would first subtract 2 from both sides of the equation, yielding 5x = 7. To find 'x', you would then divide both sides of the equation by 5. The solution to the equation, and therefore the value of the unknown number 'x', would thus be 7/5 or 1.4.

Answer:

The equation is y = 15(2)^x , the graph is X

Step-by-step explanation:

* Lets talk about the exponential graph

- The form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

 b ≠ 1, and x is any real number

- It has a constant base b

- It has a variable exponent x

- The constant a is the beginning value

* Lets solve the problem

- The sample containing 15 cells

∴ a = 15

- The cells double with each cycle ⇒ means × 2 each cycle

∴ b = 2

- x is the number of cycles

- y is the number of cells

∴ The equation is y = 15(2)^x

- From the graphs the answer could be X or Y

* To know which one substitute the values of x to find the value of y

# Figure X

∵ y = 15(2)^x

∵ x = 0

∴ y = 15(2)^0

∵ (2)^0 = 1 ⇒ any number to the power of 0 = 1 except the zero

∴ y = 15(1) = 15

∵ x = 1

∴ y = 15(2)^1 = 15(2) 30

- The graph has y = 30 when x = 1

# In the Figure Y the value of y not equal 30 at x = 1

∴ The answer is graph X

* The equation is y = 15(2)^x , the graph is X

Final answer:

The number of cells after each cycle of mitosis can be represented by an exponential growth model with the equation N = 15 × 2ⁿ. Graphically, this will be a rapidly ascending curve, starting with 15 cells at cycle 0 and doubling each cycle.

Explanation:

The question is asking us to determine the number of cells after each cycle of mitosis given an initial count of 15 cells. When a cell undergoes mitosis, it produces two genetically identical daughter cells, effectively doubling the number of cells with each cycle. To represent the number of cells after each cycle, we will need to use an exponential growth model as each cell division results in doubling the number of cells present.

The general equation representing the growth of cells through mitosis is given by N = N0 × 2ⁿ, where N is the number of cells after n cycles, N0 is the initial number of cells, and n is the number of cycles of mitosis. For the given initial condition of 15 cells (N0 = 15), the equation becomes N = 15 × 2ⁿ.

The corresponding graph to this equation would show a curve that rises sharply upward, reflecting the exponential increase in the number of cells after each cycle. The graph starts at 15 cells when n = 0 (no cycles have occurred) and doubles with each subsequent cycle.

Answer:

f(x) = x

Step-by-step explanation:

note : slope is positive 1, so the x term must be positive

also note the graph intersects the curve at y = 0, which means that they y-intercept is zero .

if we substitute this into the general equation for a line

y = mx + b, where m = +1 and b = 0,

we get y = x

or f(x) = x (in function form)

1. Divide the coefficients and the exponentials separately

[tex]\dfrac{4 \times 10^{9}}{1.5 \times 10^{6}} = \dfrac{4}{1.5} \times \dfrac{10^{9}}{10^{6}}[/tex]

2. Divide the coefficients

[tex]\dfrac{4}{1.5} \approx 2.7[/tex]

3. Divide the exponential terms

Subtract the exponent in the denominator from the exponent in the numerator.

[tex]\dfrac{10^{9}}{10^{6}} = 10^{(9 - 6)} = 10 ^{3}[/tex]

Step-by-step explanation:

This is a problem related to arithmetic progression. The formula we use is that of for nth term

[tex]a_{n}=a+(n-1)d[/tex]

Here

[tex]a=45 , d=-2 ,n=h , a_{n}=a_{h}[/tex]

[tex]a_{h}=45+(h-1)(-2)\\a_{h}=45-2(h-1)\\[/tex]

Now we have to analyse a situation when our temperature comes below 32

or

[tex]a_{h}<32[tex]

[tex]45-2(h-1)<32\\45-2h+2<32\\45-2h<32-2\\45-2h<30\\[/tex]

This is our inequality

Solving this

[tex]45-2h<30\\-2h<30-45\\-2h<-15\\h>7.5\\[/tex]

Hence in 8th hours the temperature will be below 32F

Answer:

127%

Step-by-step explanation:

All you have to do is multiply both numerator and denominator by 100.

Hello There!

1.27 to a percent would be 127%

"Percent" means "per 100" or "over 100". So, to convert 1.27 to percent we rewrite 1.27 in terms of "per 100" or over 100.

Multiply 1.27 by 100/100. Since 100/100 = 1, we are only multiplying by 1 and not changing the value of our number.

Therefore, we have shown that

1.27 = 127%
