step- by- step explanation

The equation of a line, 7x - y = -9, converted to slope-intercept form is: y = 7x + 9

If "m" is the slope of a line and "b" is the y-intercept, the equation of the line in slope-intercept form is given as: y = mx + b.

Thus, given the equation, 7x - y = -9, rewrite/convert to slope-intercept form as follows:

7x - y = -9

-y = -7x - 9

y = 7x + 9

Therefore, the equation of a line, 7x - y = -9, converted to slope-intercept form is: y = 7x + 9

Answer:

En una semana gastará 705,6 litros.

Step-by-step explanation:

Con la información proporcionada, puedes calcular cuánta agua gastará por día usando una regla de tres teniendo en cuenta que un día tiene 24 horas y estas equivalen a 1440 minutos. Además, puedes convertir los 700 ml a litros, considerando que 1 litro son 1000 mL, lo que significa que los 700 mL equivalen a 700/1000=0,7 Litros.

 10 min    →  0,7 L

1440 min →       x

x=(1440*0,7)/10

x=100,8 L

Ahora que conoces la cantidad de agua que gastará por día, puedes multiplicar esta cantidad por 7 que es el número de días en una semana:

100,8*7=705,6 L

De acuerdo a esto, la respuesta es que en una semana gastará 705,6 litros.

Answer:

y=[tex]\frac{-5}{6}[/tex]x+14[tex]\frac{5}{6}[/tex]

Step-by-step explanation:

The equation of a line is y=mx+b

to find the equation of the line you need its gradient(m) and its y intercept(b)

the gradient is

[tex]\frac{y1-y2}{x1-x2}[/tex]  

y1= the y value of the first point which is -9

y2=the y value of the second point which is -4

x1=the x value of the first point which is 7

x2=the x value of the first point which is 1

then input the values into the equation

[tex]\frac{(-9)-(-4)}{(7)-(1)}[/tex]

=[tex]\frac{-9+4}{6}[/tex]

=[tex]\frac{-5}{6}[/tex]

to find the y just times the x by the gradient and then minus it from the y

-9-(7 x [tex]\frac{-5}{6}[/tex])=14[tex]\frac{5}{6}[/tex]

making the equation y=[tex]\frac{-5}{6}[/tex]x+14[tex]\frac{5}{6}[/tex]

Answer:

The answer isn't there

Step-by-step explanation:

We can divide the figure into a rectangle and triangle and add the areas. The area of the rectangle would be length times width: 14 × 12 = 168. The area of a right angled triangle is [tex]\frac{ab}{2}[/tex], where a and b are both legs. a=12 and b=8, so the area would be [tex]\frac{12*8}{2}[/tex] which equals [tex]\frac{96}{2}[/tex], which is 48. Then we add both the areas, 168 + 48 = 216

Answer and Step-by-step explanation:

10 and 20 are the initial amounts, so they don't get a variable. The 3 dollars and 2 dollars every mile gets the variable since the occur every mile.

The equations are:

Blank 1: 3x + 10

Blank 2: 2x + 20

To find when they are equal, we equal the equations together.

3x + 10 = 2x + 20

x = 10

Plug 10 into either equation and solve.

Blank 3: 10 (At 10 miles, the equations are equal)

Blank 4: $40 (The will equal $40)

Answer:

Number of red beads = 6

Number of blue beads = 15

Step-by-step explanation:

Number of total beads = 21

Ratio of red beads to the blue beads = 2 : 5

Therefore, number of red beads I have = [tex]\frac{2}{2+5}(\text{Total number of beads})[/tex]

                                                                  = [tex]\frac{2}{7}\times 21[/tex]

                                                                  = 6 beads

Number of blue beads = [tex]\frac{5}{2+5}\times (21)[/tex]

                                      = [tex]\frac{5}{7}\times 21[/tex]

                                      = 15 beads

Therefore, number of red beads = 6

And number of blue beads = 15
