Answer:
[tex] slope (m) = \frac{1 - (-5)}{2 - (-1)} [/tex]
[tex] = \frac{1 + 5}{2 + 1} [/tex]
[tex] = \frac{6}{3} = 2 [/tex]
Step-by-step explanation:
Find the slope (m) using the two points given, (-1, -5) and (2, 1):
[tex] slope (m) = \frac{rise}{run} = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Let,
[tex] (-1, -5) = (x_1, y_1) [/tex]
[tex] (2, 1) = (x_2, y_2) [/tex]
Plug in the values into the equation:
[tex] slope (m) = \frac{1 - (-5)}{2 - (-1)} [/tex]
[tex] = \frac{1 + 5}{2 + 1} [/tex]
[tex] = \frac{6}{3} = 2 [/tex]

Write the equation in standard form.
y - 2 = -(x +4)
Answers
Answer:
x + y = - 2
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
y - 2 = - (x + 4) ← distribute by - 1
y - 2 = - x - 4 ( add x to both sides )
x + y - 2 = - 4 ( add 2 to both sides )
x + y = - 2 ← in standard form

the relationship between time and distance remaining on a 3 mile walk for someone walking at steady rate of 2 miles per hour
Answers
Let t be the remaining time.
The standard distance equation is:
d = rt
We are given the rate as 2, so:
d = 2t
At the start of the walk, the remaining distance is 3 miles.
The remaining time is 1.5 hours.
At the end of the walk, the remaining distance is 0 miles.
The remaining time is 0 hours.
A graph of the distance and time would be a continuous, solid line. That's because the walker will be at every distance between 3 and 0 and every time between 1.5 and 0.
Answer:
The graph of this would be a solid line

You have 3/5gallon of juice and drink 1/3 gallons how much is left
Answers
Answer:
4/15 gallons of juice
Step-by-step explanation:
Total gallon you have = 3/5gallons
Amount consumed = 1/3 gallons
Amount left = Total gallons + Amount consumed
Amount left = 3/5-1/3
Find the LCM
amount left = (3)(3)-5(1)/15
Amount left = (9-5)/15
Amount left = 4/15
Hence 4/15 gallons of juice is left

The equation has one valid solution and no extraneous solutions.
OD.
The equation has one valid solution and one extraneous solution.
Answers
Step-by-step explanation:
x/(x + 2) + 1/x = 1
x² + (x + 2) = x(x + 2)
x² + x + 2 = x² + 2x
x = 2.
Since x = 2 neither makes (x + 2) or x become 0, there are no extraneous solutions.
The answer is "The equation has 1 valid solution and no extraneous solutions." (C)
The true statement is (c) the equation has one valid solution and no extraneous solutions
The equation is given as:
[tex]\frac{x}{x + 2} + \frac 1x = 1[/tex]
Take LCM
[tex]\frac{x^2 + x + 2}{x(x + 2)} = 1[/tex]
Expand the numerator
[tex]\frac{x^2 + x + 2}{x^2 + 2x} = 1[/tex]
Cross multiply
[tex]x^2 + x + 2 = x^2 + 2x[/tex]
Subtract x^2 from both sides
[tex]x + 2 = 2x[/tex]
Collect like terms
[tex]2x -x = 2[/tex]
[tex]x = 2[/tex]
Hence, the equation has one valid solution and no extraneous solutions

2x = x²
0 = x² - 2x

A cube has sides of length 5 cm.
Find the total surface area of the cube.
Please explain as well, as I struggle with surface area.
Answers
25 x 6 = 150
150cm^2
Answer:
150 cm^2
Step-by-step explanation:
Keep in mind that the dimensions of the cube are identical in 6 directions. This means that the surface area of the bottom is 5 cm by 5 cm, yielding the area 25 cm^2. The top has the same area, so considering top and bottom we get a total surface area of 50 cm^2.
Likewise, the total surface area of the sides together is 50 cm^2. The total surface area of the front and back together is 50 cm^2.
Thus, the total surface area of the entirre cube is 3(50 cm^2), or 150 cm^2
Try finding how many meters they travel in ONE second) Mai and Priya were on scooters. Mai traveled 15 meters in 6 seconds. Priya travels 22 meters in 10 seconds.
Answers
Answer:
Mai travels 2.5 meters in 1 second
Priya travels 2.2 meters in 1 second
Step-by-step explanation:
Try finding how many meters they travel in ONE second) Mai and Priya were on scooters.
For Mai
Mai traveled 15 meters in 6 seconds.
Hence,
6 seconds = 15 meters
1 second = x meters
Cross Multiply
6x = 15 meters
x = 15/6
x = 2.5 meters
Hence, Mai travels 2.5 meters in 1 second
For Priya
Priya travels 22 meters in 10 seconds.
Hence,
10 seconds = 22 meters
1 second = x meters
Cross Multiply
10x = 22 meters
x = 22/10
x = 2.2 meters
Hence, Priya travels 2.2 meters in 1 second

What are similar triangles?"Two triangles are similar when their corresponding angles are equal and corresponding sides are in equal proportion."
What are congruent triangles?"Two triangles are congruent if their corresponding sides are equal and corresponding angles are equal in measure."
What is SSS congruence postulates?"Two triangles are congruent if all three sides of a triangle are congruent to corresponding three sides of other triangle."
What is SSS similarity postulates?"Two triangles are similar if all the three sides of a triangle are in proportion to the three sides of another triangle."
What is SAS similarity postulates?"Two triangles are similar if the two sides of a triangle are in the same proportion of the two sides of another triangle, and the angle between the two sides in both the triangle are equal."
What is SAS congruence postulates?"Two triangles are congruent if two sides and the angle between these two sides of one triangle are congruent to the corresponding two sides and the included angle of a second triangle."
For given question,
We have been given triangles ABD and CBD.
B is the midpoint of line AC
⇒ AB = BC
For triangles ABD and CBD,
side AB = side CB ............(since, B is the midpoint of line AC)
side BD = side BD .............(common side)
side AD = side CD ............(measures 15 units each)
So, by SSS postulates of triangle congruence triangles ABD and CBD are congruent triangles.
Therefore, the statement that best describes the relationship between triangles ABD and CBD is 'Triangles ABD and CBD are congruent by the SSS Congruence postulate'
