Mathematics

Kazeer [188]3 years ago
8 0

Answer:

The center is the point (-1,2)

Step-by-step explanation:

we know that

The center of the circle is equal to the midpoint of the endpoints of the diameter

so

The formula to calculate the midpoint between two points is equal to

M(\frac{x1+x2}{2},\frac{y1+y2}{2})

substitute the values

M(\frac{-7+5}{2},\frac{3+1}{2})

M(\frac{-2}{2},\frac{4}{2})

M(-1,2)

therefore

The center is the point (-1,2)

El día del estreno de una película se vendieron 600 entradas y se recaudaron 196 250 soles. Si los adultos pagaban 400 soles. y
gulaghasi [49]

Por medio de sistema de ecuaciones:

*adultos (a) = $400

*niños (b) = $150

total de entradas : a + b = 600 ecua 1

dinero recaudado:

400a + 150b = 196 250 ecua 2

operamos:

a + b = 600 ecua 1

400a + 150b = 196 250 ecua 2

--------------------------

(-150) a + b = 600

400a + 150b = 196 250

-----------------------

- 150a - 150b = -90 000

400a + 150b = 196 250

-----------------------

250a = 106 250

a = 106 250/250

a = 425 adultos

a + b = 600

425+b =600

b = 600-425

b = 175 niños

comprobacion:

400a + 150b = 196 250

400(425)+150(175)=196 250

170 000 + 26 250 = 196 250

196 250 = 196 250
