stiks02 [169]

Answer:

c=120x+200y

Step-by-step explanation:

La expresión algebraica debería indicar que el valor total que debe cobrar Flor es igual a 10 que representa el número de bolsas por el resultado de la suma del precio de cada item por la cantidad, lo que se puede expresar de la siguiente forma:

c=10(12x+20y)

c=120x+200y

Fine the equation of the line that is perpendicular to the given line and passes through the given point. Enter the right side o
Kipish [7]

Answer:

y=-\frac{4}{7} x+\frac{55}{7}

Step-by-step explanation:

Change the given equation to slope-intercept to get y=\frac{7}{4}x-\frac{1}{4}. When you multiply the slopes of perpendicular lines, you get -1. -1 divided by \frac{7}{4} is -\frac{4}{7}. The slope of the new line is then -\frac{4}{7}. The perpendicular line passes through (5, 5) so you can have the equation5=-\frac{4}{7} (5)+b. Simplifying gets b = \frac{55}{7} . So now the final equation for the perpendicular line is y=-\frac{4}{7} x+\frac{55}{7}
