find the slope of the line that contains (-2,-2) and (-10,-9)
Answer:
[tex] \huge \frac{7}{8} \\ [/tex]
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]
From the question we have
[tex]m = \frac{ - 9 - - 2}{ - 10 - - 2} = \frac{ - 9 + 2}{ - 10 + 2} = \frac{ - 7}{ - 8} = \frac{7}{8} \\ [/tex]
We have the final answer as
[tex] \frac{7}{8} \\ [/tex]

7x - 2 = 9x+5
Please help!!
Answer:
x=-7/2
Step-by-step explanation:
Answer:
x = -7/2 or -3.5
Step-by-step explanation:
7x - 2 = 9x + 5
Add 2 to both sides
7x = 9x + 7
Subtract 9x from both sides
-2x = 7
Divide both sides by -2
x = -7/2
x = -3.5

Solve the following system of equations using a method of your choice.
Write the solution as an ordered pair ( , ) and then you will be prompted to explain your thinking.
4x-2y=4
x+y=10
Answer:
Step-by-step explanation:
cant remember what this method is called but
change the second equation to be y = something
x + y = 10
y = -x + 10
plug in this y= in the first equation to get x
4x -2(-x + 10) = 4
4x + 2x -20 = 4
6x = 24
x = 4
then plug in the x we found into the original second equation
4 + y = 10
y = 6
so your ordered pair would be (4,6)

Noah would like to cover a rectangular tray with rectangular tiles. The tray has a width of 11 1/4 inches and an area of 50 5/8 square inches. Find the length of the tray in inches.
Answer:
67 sq ft
Step-by-step explanation:
The length of the rectangle with an area of 405/8 square inches and a width of 45/4 inches is 9/2 inches.
What are the area and perimeter of a rectangle?The area of a rectangle is the product of its length and width.
The perimeter of a rectangle is the sum of the lengths of all the sides.
We know the area of a rectangle = length×width.
Given, The tray has a width of 45/4 inches and an area of 405/8 square inches.
∴ If area = length×width.
Then, length = area/width.
length = (405/8)/(45/4) inches.
length = (405/8)×(4/45) inches.
length = 9/2 inches.

11 students in the Environmental club represent 4% of the students in the seventh grade. How many students are in the seventh grade?
Answer:
275
Step-by-step explanation:
The best way to do this is to set it up in this equation:
4/100 = 11/x, in this, the 4 over 100 represents 4% out of 100%. The 11 over x represents the 11 students out of x amount of students. With this equation, you cross multiply to get 4x = 1100. Then you divide both sides by 4 to get x by itself. This will give you x=275
After solving the equation, the total number of students in the 7th grade is 275.
What is the Percentage?The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from. Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.
As per the data mentioned in the question,
Total number of students in the Environmental club = 11
Percentage of students from 7th grade = 4%
Let the total number of students in 7th grade be x
Then, the equation according to the statement will be,
4% of x = 11
So,
x = (11 × 100)/4
x = 275

Answer: Choice B) The plane is at least 20 times faster than the bird
========================================================
Explanation:
We'll divide the speed of the plane over the speed of the bird.
First divide each coefficient of the scientific value expressions:
7/3 = 2.33 approximately
Then divide the 10^n exponent expressions and we get
10^3 divide by 10^2 = 10^(3-2) = 10^1
So overall, the result of dividing the two speeds leads to approximately
2.33*10^1 = 2.33*10 = 23.3
This shows the plane is approximately 23.3 times faster compared to the bird. Saying "The plane is at least 20 times faster than the bird" is fairly close to the prior sentence, so the statement is valid. That's why choice B is the answer.
Choices A and C are saying similarly valid statements, just written in different formats. I think choice B is the best answer since it seems to be the most direct comparison that is fairly easy to grasp.

Given parameters
Percentage of all teachers the works in summer = 85%
Number of teachers sampled = 6 teachers
Unknown:
The probability that they all work in summer = ?
Solution:
Now, to solve this problem, let us find the number of teachers that works in summer from the given size;
Number of teachers = 85% x 6 = 5.1;
Since it is not possible to have 5.1 people, the number of teachers will be 5
The probability = [tex]\frac{5}{6}[/tex]

Predict the violent crime rate for a Southern state with an urbanization of 55.4 and a poverty rate of 13.7.
Answer:
The violent crime rate for this Southern state with an urbanization of 55.4 and a poverty rate of 13.7 is predicted to be:
7.6%.
Step-by-step explanation:
a) Data and Calculations:
Urbanization rate = 55.4%
Poverty rate = 13.7%
The predicted violent crime rate = urbanization rate * poverty rate
= 55.4% * 13.7%
= 7.5898%
= 7.6%
b) The prediction of violent crime rate follows some established researches that show that crime rates are higher in urban than rural areas. There is also a dynamic link between poverty, unemployment, and crime rate. Unemployment is usually high in more urbanized areas. As a result, unemployment increases poverty, and poverty reinforces the commission of crimes.

Answer:
x = 26
2x = 52
(5x - 2) = 128°
Step-by-step explanation:
✔️According to the exterior angle theorem of a ∆, thus:
(5x - 2)° = 2x° + 76°
Solve for x
5x - 2 = 2x + 76
Collect like terms
5x - 2x = 2 + 76
3x = 78
Divide both sides by 3
x = 26
✔️2x
Plug in the value of x
2(26) = 52°
✔️5x - 2
Plug in the value of x
5x - 2 = 5(26) - 2
= 128°

Slope = -2
Step-by-step explanation:
Since, slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
Rise = -(y-intercept)
Run = (x-intercept)
From the graph attached,
y - intercept = -(4) = -4
x - intercept = 2
Therefore, slope the line given in the graph attached will be,
Slope = [tex]\frac{-4}{2}[/tex] = -2
Slope = -2
