Answer:

Option C) There is exactly one solution to this equation, and the solution is 0 is correct

That is the solution x=0

Step-by-step explanation:

Given equation is -4(x+2)+x=3x-8-5x

To find the solution to the given equation :

First to solve the given equation

-4(x+2)+x=3x-8-5x

-4x-8+x=3x-8-5x ( by using the distributive property )

-3x-8=-2x-8 ( adding the like terms )

-3x-8-(-2x-8)=-2x-8-(-2x-8)

-3x-8+2x+8=-2x-8+2x+8  ( adding the like terms )

-x=0

Therefore x=0 is the only solution to the given equation

Option C) There is exactly one solution to this equation, and the solution is 0 is correct

That is the solution x=0

After simplifying and solving the given equation, it is clear that the single solution is x = 0, which corresponds to option C.

To identify the correct statement describing the solution to the given equation, we need to solve the equation step by step:

-4[x+2]+x = 3x - 8 - 5x.

First, distribute the -4 across the terms inside the brackets:

-4x - 8 + x = 3x - 8 - 5x.

Combine like terms:

-3x - 8 = -2x - 8.

Then add 3x to both sides:

-8 = x - 8.

Finally, add 8 to both sides to solve for x:

x = 0.

The equation simplifies to x = 0, which means there is a single solution to this equation. Therefore, the correct option is: C. There is exactly one solution to this equation, and the solution is 0.

Answer:

Thymine 23

Guanine 27

Step-by-step explanation:

A DNA molecule consists of two long chains of DNA connected to each other through the bonds nitrogenous bases make one with another. However, this bonding is strictly regulated through Chargaff's rule. It basically says that adenine from one DNA chain can only bond with thymine from another chain and vice versa. Additionally, cytosine from one chain only bonds with guanine from another and vice versa:

[A] = [T]

[G] = [C]

That means that there should be an equal number of corresponding bases.

If there were 23% of adenine, there will also be 23% of thymine.

Similarly, if there were 27% of cytosine, there will also be 27% of guanine.

Also note that the sum of non-bonding bases is always 50%, in this case, adenine + cytosine was 23% + 27% = 50%.

The Answer is: Thymine 23

Then Guanine 27

Division property of equality is used

Solution:

Given that,

If 3x = 27 then x = 9

We have to find the algebraic property used here

Division property is used here

The division property of equality is a property that tells us if we divide one side of an equation by a number, we must also divide the other side by the same number so that our equation stays the same.

Given equation is:

3x = 27

Divide both the sides by 3

[tex]\frac{3x}{3} = \frac{27}{3}\\\\x = 9[/tex]

Thus division property of equality is used

The algebraic property used in changing 3x = 27, to x = 9 is the Division Property of Equality. This property means that if both sides of an equal equation are divided by the same nonzero number, then the resulting equation remains true.

The algebraic property that applies when rearranging the equation 3x = 27, to x = 9 is known as the Division Property of Equality. This property states that when both sides of an equation are divided by the same nonzero number, the result is an equivalent equation.

To demonstrate this, in the given equation 3x = 27 we can apply the Division Property of Equality by dividing both sides of the equation by 3. This will give: 3x/3 = 27/3 which simplifies to x = 9, thus demonstrating the division property of equality.

Final answer:

The missing fraction in the equation 9/10 + ?/? = 99/100 is 9/100 because 9/10 is equivalent to 90/100 and 99/100 - 90/100 equals 9/100.

Explanation:

To find the missing fraction in the equation 9/10 + ?/? = 99/100, we need to find a common denominator and then solve for the numerator of the missing fraction. The common denominator for 10 and 100 is 100, so we must convert 9/10 into an equivalent fraction with a denominator of 100, which is 90/100. Now, to find the missing numerator, we subtract 90/100 from 99/100 which gives us 9/100. Therefore, the missing fraction is 9/100.

Answer:

y = 5x - 17

Step-by-step explanation:

y = mx + c

m = the gradient/slope = 5

y = 5x + c

Substitute (3, -2) into the equation above to find c.

-2 = 5(3) + c

-2 = 15 + c

-2 - 15 = c

-17 = c

y = 5x - 17

Answer:

Step-by-step explanation:

point(3, -2) and has a slope of 5

Slope m = 5

y1 = -2 and x1 = 3

The equation is

y - y1 = m(x - x1)

y + 2 = 5(x - 3)

y + 2 = 5x - 15

y = 5x - 15 - 2

y = 5x - 17

Answer:

b < –2 or b > 2

Step-by-step explanation:

The given expresion is

[tex] |b| \: > \: 2[/tex]

By the definition of absolute value function.

|x|=x, if x>0

|x|=-x, if x<0

This implies that:

[tex] b \: > \: 2 \: or \: - b \: > \: 2[/tex]

Divide the second inequality by -2 and reverse the sign

[tex]b \: > \: 2 \: or \: b \: < \: - 2[/tex]

Option B is correct

The expression |b| > 2 is equivalent to b < -2 or b > 2, indicating that the value of b is either greater than 2 or less than -2.

The expression |b| > 2 is equivalent to the situation where b is greater than 2 or less than -2. The absolute value sign indicates the distance of b from 0 on a number line, without considering direction. Therefore, if |b| is greater than 2, b must lie outside the interval from -2 to 2, since anything within that interval would have an absolute value less than or equal to 2.

This means that the correct expression equivalent to |b| > 2 is b < -2 or b > 2. When b is positive, it must be greater than 2 to satisfy the inequality. When b is negative, to have an absolute value greater than 2, it must be less than -2.

Answer: OPTION C.

Step-by-step explanation:

In order to solve the given exercise, you can follow these steps:

1. Given the following function f(x):

[tex]f(x)=\frac{x-2}{3}[/tex]

You must substitute [tex]x=2[/tex] into the function f(x). Then:

[tex]f(2)=\frac{(2)-2}{3}[/tex]

2. Evaluating, you get:

[tex]f(2)=\frac{0}{3}\\\\f(2)=0[/tex]

3. Now, the next step is to substitute [tex]f(2)[/tex]  into the function g(x):

[tex]g (x) = 3x+2\\\\g (f(2)) = 3(0)+2[/tex]

4. Finally, evaluating, you get the following result:

[tex]g (f(2)) = 0+2\\\\g (f(2)) =2[/tex]

You can identify that it matches with the Option C.

To find the value of g(f(2)), we first calculate f(2) which equals 0, then we substitute that into g(x) to get g(0) which equals 2. Therefore, g(f(2)) is 2.

The question asks for the value of g(f(2)) given two functions g(x) = 3x + 2 and f(x) = (x - 2) / 3. To find the value, we first evaluate f(2), and then plug that result into g(x).

The answer to the given function composition g(f(2)) is 2, which corresponds to option C.

It takes 6 days for both of them to have same number of followers

Solution:

Let "x" be the number of days

Celebrity A has 400 followers on social media and is gaining 75 followers each day

We can frame a equation as:

Celebrity A : 400 + 75(number of days)

Celebrity A : 400 + 75x --------- eqn 1

Celebrity B has 1,000 followers on social media, but is losing 25 followers a day

We can frame a equation as:

Celebrity B : 1000 - 25(number of days)

Here we use negative sign to denote losing of followers

Celebrity B : 1000 - 25x --------- eqn 2

For both of them to have same number of followers, eqn 1 must be equal to eqn 2

[tex]400 + 75x = 1000 - 25x\\\\\text{Solve the above equation for x}\\\\75x + 25x = 1000 - 400\\\\\text{Combine the like terms }\\\\100x = 600\\\\x = 6[/tex]

Thus it takes 6 days for both of them to have same number of followers

There are 24 hours in a day so multiply 600 with that and you have ur answer. 24×600=14400. Also sorry this is probably old.

A bird chirps 14,400 times in a day.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

A bird chirps 10 times a minute.

Now,

Since, A bird chirps 10 times a minute.

We know that;

1 day = 24 hours

        = 24 × 60 minutes

        = 1,440 minutes

Hence, We get;

A bird chirps in a day = 10 × 1,440

                                 = 14,400 times

Thus, A bird chirps 14,400 times in a day.

Two lines are said to be perpendicular if the product of their slope = -1, that is , if [tex]m_{1}[/tex] is the slope of the first line and [tex]m_{2}[/tex] is the slope of the second line , if the two lines are perpendicular , then [tex]m_{1}[/tex][tex]m_{2}[/tex] = -1

The equation of the line given :

y = 1/2x - 1

comparing with the equation of line in slope intercept form

y = mx + c , where m is the slope and c is the y - intercept , it implies that

[tex]m_{1}[/tex] = 1/2

Therefore :

[tex]m_{2}[/tex] = -2

To find the equation of the line with slope -2  and passes through the point ( 3 , 4 ) we will use the formula

[tex]y-y_{1}[/tex] = m ([tex]x-x_{1}[/tex] )

y - 4 = -2 ( x - 3 )

y - 4 = -2x + 6

y = -2x + 6 + 4

AB = 145 m

Using pythagoras theorem to find AC.

[tex]AC^2+BC^2=AB^2\\AC^2+(80)^2=(145)^2\\AC^2+6400=21025\\AC^2=21025-6400\\AC^2=14625[/tex]

Taking square root on both sides

[tex]\sqrt{AC^2}=\sqrt{14625}\\AC=120.93m[/tex]

Length of swimming course = AB + BC + AC

Length of swimming course = 145 + 80 + 120.93 = 345.93 m
