Answer:

  x = -5

Step-by-step explanation:

You want the solution to 8-(x+12)=1.

Eliminate parentheses using the distributive property:

  8 -x -12 = 1

Combine like terms.

  -4 -x = 1

We like to have the x-coefficient be positive, so we're going to add x to both sides:

  -4 = 1 +x

Subtract 1 to get x by itself.

  -5 = x

The value of x is -5.

__

Additional comment

We could have solved this by adding 4 to both sides in the third step:

  -x = 5

Now, we need to multiply (or divide) by -1:

  x = -5

Any operation (add, subtract, multiply, divide, root, log, or any other function) is done to both sides of the equation, according to the properties of equality.

Answer:

251.2

Step-by-step explanation:

The formula for the volume of a cylinder is [tex]\pi r^2h[/tex]. Plugging in your measurements...

Height = 20 inches.

Radius = 2 inches.

The volume is [tex]\pi2^2h[/tex].

Simplification...

[tex]\pi2^220 = \pi4(20)= 4\pi 20[/tex].

[tex]\pi[/tex] ≈ [tex]3.14[/tex]

3.14 * 4 = 12.56

12.56*20 = 251.2

[tex]\textsf{3.} \quad y=a \cdot 2^{2}\;\;\textsf{(where $a$ is the initial population)}[/tex]

[tex]\textsf{4.} \quad y=a \cdot 2^{8}\;\;\textsf{(where $a$ is the initial population)}[/tex]

[tex]\textsf{5.} \quad 64[/tex]

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{9 cm}\underline{General form of an Exponential Function}\\\\$y=ab^x$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the initial value ($y$-intercept). \\ \phantom{ww}$\bullet$ $b$ is the base (growth/decay factor) in decimal form.\\\end{minipage}}[/tex]

Given that organism A's population doubles every day for the first 5 days:

Therefore, an exponential expression to express organism A's population growth in the first 5 days is:

[tex]\boxed{y=a \cdot 2^5}[/tex]

(where a is the initial population).

Given expression showing organism A's decrease in population over the next 3 days:

To rewrite the expression with the same base but one exponent,

[tex]\textsf{apply the exponent rule} \quad (a^b)^c=a^{bc}:[/tex]

[tex]\implies 2^{-3}[/tex]

Combine the increase and decrease in organism A's population after 8 days by multiplying the rates.  So the exponential expression for the total change in organism A's population after 8 days is:

[tex]\implies y=a \cdot 2^5 \cdot 2^{-3}[/tex]

[tex]\textsf{Apply the exponent rule} \quad a^b \cdot a^c=a^{b+c}:[/tex]

[tex]\implies y=a \cdot 2^{5-3}[/tex]

[tex]\implies y=a \cdot 2^{2}[/tex]

As organism B's population grows at the same rate as organism A, but is not infected with the virus, its population doubles each day.  Therefore, an exponential expression showing its increase in population over the same 8 days is:

[tex]\boxed{y=a \cdot 2^8}[/tex]

where a is the initial population.

To calculate how many times greater organism B's population is than organism A's population after 8 days, divide the expression for organism B by the expression for organism A:

[tex]\implies \dfrac{a \cdot 2^8}{a \cdot 2^2}[/tex]

[tex]\implies \dfrac{2^8}{2^2}[/tex]

[tex]\textsf{Apply the exponent rule} \quad \dfrac{a^b}{a^c}=a^{b-c}:[/tex]

[tex]\implies 2^{8-2}[/tex]

[tex]\implies 2^6=64[/tex]

By using the vertical line test, the relation graphed above is a function. Therefore, the correct answer choice is: A. yes.

In Mathematics, a vertical line test can be defined as a technique which is typically used to determine whether or not a given relation is a function.

According to the vertical line test, a vertical line must cut through the x-coordinate (x-axis) on the graph of a function at only one (1) point, in order for it to represent a function. Else, the relation does not represent a function because it can only have one output value (y) for a unique input value (x).

In conclusion, we can reasonably infer and logically deduce that relation graphed above represents a function because it passed the vertical line test as shown in the graph attached below.

Step-by-step explanation:

Answer:

Step-by-step explanation:

.................................

The lines are perpendicular because the product of their slopes is -1

The slope-intercept form of the equation of a straight line is:

y = mx + c,

where m is the slope and c is the y-intercept

When two lines are perpendicular, the product of their slope is -1 i.e.

m₁ × m₂ = -1

where m₁ and m₂ represent the slope of the lines

But when two lines are parallel, they have the same slope i.e.

m₁ = m₂

Let's examine the equations:

y-3=4(x+4) and x+4y=16

First write the equations in slope-intercept form. That is:

y-3 = 4(x+4)

y-3 = 4x+16

y = 4x+16+3

y = 4x+19   (slope, m = 4 )

x+4y = 16

4y = -x + 16

y = (-1/4)x + 4   (slope, m = -1/4 )

Since the slopes of the lines are not the equal, they are not parallel.

Since the product of the slopes of the line is -1 (i.e. 4 × -1/4 = -1), they are perpendicular.

Answer: 0

Step-by-step explanation:

To find the y-coordinate of point Q, we first need to find the coordinates of point Q. Since points P, Q, and R are collinear and the ratio of PQ to PR is 3/4, we know that the ratio of their x-coordinates and y-coordinates must also be 3/4.

Let's call the coordinates of point Q (x, y). We know that the x-coordinate of point Q is 3/4 of the way between the x-coordinates of points P and R. This means that the x-coordinate of point Q is (3/4) * (-4 - 3) + 3 = -1.

Similarly, the y-coordinate of point Q is (3/4) of the way between the y-coordinates of points P and R. This means that the y-coordinate of point Q is (3/4) * (5 - (-5)) - 5 = 0.

Therefore, the coordinates of point Q are (-1, 0). The y-coordinate of point Q is 0.

The coordinates of point Q are (3, -5), and the y-coordinate of point Q is -5.

Collinear points are points that lie on the same straight line. In other words, if you can draw a straight line through two or more points, then those points are said to be collinear.

Given that the ratio of PQ to PR is 3/4.

Let's assume the coordinates of point Q are (x, y).

Using the midpoint formula, we can find the coordinates of the midpoint M of line segment PR:

M = ((x1 + x2)/2, (y1 + y2)/2)

Substituting the coordinates of points P (3, -5) and R (-4, 5), we have:

M = ((3 - 4)/2, (-5 + 5)/2) = (-1/2, 0)

and, M = ((x + (-4))/2, (y + 5)/2)

Equating the x-coordinates and y-coordinates, we get:

-1/2 = (x - 4)/2 => x - 4 = -1 => x = 3

0 = (y + 5)/2 => y + 5 = 0 => y = -5

Therefore, the coordinates of point Q are (3, -5), and the y-coordinate of point Q is -5.

The value of the function f(g(1)) = 1

A function is a mathematical expression that shows the relationship between two variables.

Consider functions f and g.

f(x) = 3 √x + 1, to determine the value of f(g(1)), we substitute g(x) into the equation for f(x).

So, f(x) = 3 √x + 1

f(g(x)) = 3√x + 1

f(g(x)) = 3√g(x) + 1

So, substititng x = 1, we have that

f(g(1)) = 3√g(1) + 1

We see that from the table g(1) = 0.

So, susbtituting the values of the variables into the equation, we have that

f(g(1)) = 3√g(1) + 1

f(g(1)) = 3√0 + 1

= 3(0) + 1

= 0 + 1

On solving the provided question, we can say that - here in inequality equation  value of p for the inequality [tex]4p - 5 \leq 25[/tex] is [tex]7.5[/tex]

A connection between two expressions or values that is not equal in mathematics is referred to as an inequality. Inequality results from an imbalance, thus. In mathematics, an inequality establishes the relationship between two values that are not equal. Egality is not the same as inequality. Use the not equal symbol () in most cases when two values are not equal. To contrast values, whether they are tiny or huge, different inequalities are employed. By adjusting both sides until just the variables are left, you may eliminate many straightforward inequalities. However, several factors cause inequality: Divide or add negative values on both sides.

The mean, median, and mode 0, 4, 6, 11, 9, 8, 9, 1, 5, 9, 7 are 6.2, 7, and 9.

A median is a middle number in a series of numbers that have been arranged to lift, and it might be more informative of the set of data than the average. When there are extremes in the sequences that might affect the average of the numbers, the median is sometimes employed instead of the mean.

From the data set:

0, 4, 6, 11, 9, 8, 9, 1, 5, 9, 7

Mean = ( 0+ 4+ 6+11+ 9+ 8+ 9+ 1+ 5+ 9+7)/11 = 6.2

The mean is the middle number(s) in a data set. Hence

Median = 7

The mode is the most occurring number in a data set

Hence,

Mode = 9

Thus, the mean, median, and mode 0, 4, 6, 11, 9, 8, 9, 1, 5, 9, 7 are 6.2, 7, and 9.
