3 0

Answer:

X = -1,625

Y = 2,5

Step-by-step explanation:

-4x + y = 9

4x + 9y = 17

10y = 25

-4x + y = 9

y = 2,5

-4x + 2,5 =9

y = 2,5

-4x = 6,5

y = 2,5

x = -1,625

so there is only 1 solution for this equation is (-1,625; 2,5)

Done :))

Explain how to draw a circle with a circumference of π2 inches. OPTIONS : The circle has a diameter of π2 inches, so use a diame
WINSTONCH [101]

Answer:

he circle has a radius of π inches, so use a radius of about 3.1 inches.

Step-by-step explanation:

The circumference of a circle can be described as the linear distance round the circle

The circumference of a circle = 2nr

n = 3.14

r = radius

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

diameter = 2r

If diameter = n2

diameter = 3.14 x 2 = 6.28

Radius = 1/2 x diameter = 6.28/2 = 3.1
