this is all we need
[tex]y = mx + b\\ m = \frac{y_2-y_1}{x_2-x_1} = \frac{5-(-1)}{0-3} = -2[/tex]

brynne simplifies an equation and gets 2=3. what does this tell you about the equation
Answer:
That it has no solution. If you could have gotten 2=2 or 3=3 it would have a solution
Step-by-step explanation:
Answer:
The equation is not equal. Therefore, it is not an equation. However, things will be different if the equation was based on a coordinate plane. If it was based on a coordinate, the equation could have been: y=x-1

Solve 4(2x - 9) = 3x + 4
Answer:
x = 8
Step-by-step explanation:
First, you distribute
4(2x)+4(-9)=3x+4
8x - 36 = 3x + 4
Subtract 3x from both sides
(8x - 3x) - 36 = (3x - 3x) + 4
5x - 36 = 4
Then add 36 to both sides
5x (-36 + 36) = (4 + 36)
5x = 40
Then divide 5 from both sides
x = 8

Un bloque de 2kg es trasladado a lo largo de la superficie lisa por accion de una fuerza f=40N ¿cual es el trabajo realisado por la fuerza "f"y por la fuersa de gravedad para un recorrido de 6m?
Explicación paso a paso:
Workdone = Fuerza * distancia movida en la dirección de la fuerza
Dado
Fuerza f = 40N
Distancia = 6 m
El trabajo realizado por la fuerza F es:
Trabajo hecho = 40 * 6
Trabajo terminado = 240 Nm
El trabajo realizado por la fuerza de la gravedad es el trabajo realizado por el cuerpo de 2 kg:
W = mg
W = 2 * 10
W = 20N
Trabajo realizado = 20 * 6
Trabajo terminado = 120 Nm

14 minus the product of a number and 15
Answer:
14 - (y x 15)
Step-by-step explanation:
This is the number because:
1) 14 minus means 14 subtracted from the product of a number and 15
2) The product of a number and 15 is a variable multiplied with 15
3) Finally, if we put these together, we get 14 - (y x 15)

Paulo has 39 patches from states he and his relatives have visited he wants to pin the onto a board and arrange them equally in 3 rows how many patches will be in each row
Given:
Total number of patches = 39
Total number of rows = 3
To find:
The number of patches in each row.
Solution:
We have,
Total number of patches = 39
Total number of rows = 3
We need to divide the total number of patches by total number of rows to find the number of patches in each row.
[tex]\text{Number of patches in each row}=\dfrac{39}{3}[/tex]
[tex]\text{Number of patches in each row}=13[/tex]
Therefore, the number of patches in each row is 13.

Caroline is planting flowers in her garden. She plants her first 7 flowers in 4 minutes. After 12 minutes, she has planted 21 different flowers.
Which equation represents this direct variation?
The answer is B) y= 7/4x
This is because when you graph it you would go up 7 and over 4- you just had to find the rise over run. I also just made sure it was correct on edmentum!
Caroline is planting her first 7 flowers in 4 minutes and then past 12 minutes, she plants 21 different flowers. That suggests that she is planting the flowers following the given equation y=(7/4)x.
What is dependant variable?The dependent variable is defined as the variable whose evaluation of the independent variable determines the quality of the dependent variable. That is, it is consistently claimed that the word variable's estimate depends on the mathematical condition's free variable.
How to solve it?Let Caroline plant y flowers in x minutes.
By using the unitary method we can observe that
4 minutes → 7 flowers
⇒ 1 minute → 7/4 flowers
⇒ x minutes → (7/4)x flowers
Hence, Caroline is planting y=(7/4)x flowers in x minutes. And y=(7/4)x this equation represents the variation perfectly.
NOTE: We took the number of flowers planted as y because it is a dependent variable. The number of flowers depends on the time elapsed.
