Therefore , algebraic solution is 55 is the total amount of money Peter earns raking lawns in August and September

What is the total amount of money Peter earns raking lawns in August and September?

The total amount of money Peter earns from raking lawns in August and September can be found by solving the equation 5 x 8 + 10 = m, where m represents the total money earned.

Here,

In this equation, 5 represents the number of lawns Peter raked in August, 8 represents the amount he earns for each lawn, and 10 represents the amount he earned from raking lawns in September.

When this equation is solved, the result is m = 55, meaning that Peter earned a total of $55 from raking lawns in August and September.

This can be seen by multiplying 5 times 8, which is 40, and then adding 10, which brings the total to 55.

Therefore, the total amount of money Peter earns from raking lawns in August and September is $55.

Answer: 806.59300

Step-by-step explanation:

When you’ve finished solving an equation, it’s easy to check your work. Simply plug your answer for the variable into the original equation. Take, for example, the equation 4x + 9 = 45. After isolating the variable, you’ve come up with x = 9. To check your work, replace the x with 9: 4(9) + 9 = 45. Following the order of operations, multiply 4 by 9 first to get 36 + 9 = 45. Adding 36 plus 9 does equal 45, so you know you’ve found the right value for x. Which of these equations is correct when x = -2? A x + 8 = 5 B 3x - 1 = -10 C 2x - 7 = -11 D -95x = -190 BACK

Answers

The required correct equations are 2x - 7 = -11 and -95x = -190. Options C and D are correct.

What is the equation?

The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.

Here,
As of the given example in the question,
Putting x = -2 to in every op[tion,

A,
X + 8 = 5
-2 + 8 = 5
6 ≠ 5

Similarly,
B. -7 ≠ -10
C. -11 = -11
D. -190 = -190

Thus, the required correct equations are 2x - 7 = -11 and -95x = -190. Options C and D are correct.

Line C is represented by the line

Answers

from the given option the slope of the line -5/2 is shown by the equation   [tex]$y=-\frac{5}{2} x-4$[/tex]that is option B).

What is slope of Line?

An indication of how steep a line is is its slope. When calculating slope mathematically, "rise over run" is used (change in y divided by change in x). Measured by slope, a line's steepness. The slope increases in steepness as it gets larger. It becomes flatter the smaller the slope. Along with indicating whether a line is going up, down, horizontal, or vertical, slope also indicates the direction of the line.

From the given option the slope of the line [tex]$-5 / 2$[/tex] is shown by the equation [tex]$y=\frac{2}{5} x[/tex] that is option[tex]$\mathbf{B}$[/tex] ) and this can be determined by using the slop intercept form.

Given :

Equation -[tex]$y=\frac{2}{5} x-1$[/tex]

First, determine the slope of the given line by using the slope-intercept form. The slope-intercept is given by the equation:

[tex]$$y=m x+c$$[/tex]

Now, compare equation (1) with the above equation.

[tex]& \mathrm{m}_1=\frac{2}{5} \\[/tex]

[tex]& \mathrm{c}=-1[/tex]

For a line to be perpendicular to the other line the product of the slope of both the line is equal to -1, that is:

[tex]$$m_1 m_2=-1$$[/tex]

So, the slope of the line perpendicular to the line [tex]$y=\frac{2}{5} x-1$[/tex] is:

[tex]$$\mathrm{m}_2=-\frac{5}{2}$$[/tex]

So, from the given option the slope of the line [tex]$-5 / 2$[/tex] is shown by the equation [tex]$y=-\frac{5}{2} x-4$[/tex] that is option[tex]$\left.\mathbf{B}\right)$[/tex].

The complete question is,

Answers

The function that represents how many more texts that were sent this week than last week is: B. (f − g)(x) = 3x + 16.

How to Evaluate Functions?

To find the value of a given functional expression, we have to apply the basic knowledge of how to solve algebraic expressions.

For example, if we are given that (f - g)(x), it means we are to subtract the function g(x) from f(x). That is (f - g)(x) = f(x) - g(x).

Given the following functions:

Number of texts sent this week is represented as the function, f(x) = 8x + 14

Number of texts sent last week is represented as the function, g(x) = 5x - 2.

Number of texts that were sent this week than last week = (f - g)(x)

(f - g)(x) = (8x + 14) - (5x - 2)

(f - g)(x) = 8x + 14 - 5x + 2

(f - g)(x) = 3x + 16

Therefore, the answer is: (f − g)(x) = 3x + 16.

A unique plane and triangle in Euclidean geometry are discovered when the three points are not collinear. Three sides and three corners define a triangle as a polygon.

If the mean of this data is 95, find the missing data. 103, 99, 90, 86, 105, 96, ___​

Answers

Answer: The missing value is 86

Step-by-step explanation: The mean of a data set is the same as the average. The formula for mean is the sum of the data values/(the number of data values). Right now there are only 6 data values and we are looking for a seventh. If we sum the 6 current values and divide by 6, we get a data set with a mean of 96.5. We need a lower mean. The data set we need has 7 points so the sum of all 7 points should be 7(95) since if we divide 7(95) by the number of points which is 7, we get 95 which is the mean we want. 7(95) is 665. We can subtract the sum of the current 6 points from 665 to find the value we want.

Find the differential of each function. (a) y - x^2 sin 8x

Answers

The differential of the function y - x² sin 8x with respect to x is dy/dx - 2x sin 8x + 8x² cos 8x

To find the differential of the function y = x² sin 8x, we can use the standard notation dy/dx which represents the rate of change of y with respect to x.

To calculate dy/dx, we need to use the product rule, which states that the derivative of the product of two functions is the derivative of the first function times the second function plus the first function times the derivative of the second function.

Let z be the given function,

z= y - x² sin 8x

The derivative of x² is 2x

The derivative of sin 8x is 8 cos 8x

So,

dz/dx= dy/dx - (2x)(sin 8x) + (x²)(8cos 8x)

= dy/dx- 2x sin 8x + 8x² cos 8x

Probability is used to determine how likely it is that a random event would happen. The probability that a random event occurs lie between 0 and 1.  The more likely the event is to happen, the closer the probability value would be to 1. The less likely it is for the event not to happen, the closer the probability value would be to zero.

Definition of Degree: The maximum power in an equation of variable is known as a degree.

So, the degree of a linear equation is 1.

Linear equations are equations based on the first order. The linear equations are explained for lines in the coordinate system. When the equation has a homogeneous variable of degree 1 (i.e., only one variable), then it is known as a linear equation in 1 variable.
