X+y=10
5x+y=-2
What is the y and x value

x = - 3, y = 13

Step-by-step explanation:

Given the 2 equations

x + y = 10 → (1)

5x + y = - 2 → (2)

Subtracting (1) from (2) term by term eliminates the y- term, that is

(5x - x) + (y - y) = (- 2 - 10), that is

4x = - 12 ( divide both sides by 4 )

x = - 3

Substitute x = - 3 in either of the 2 equations for corresponding value of y

Substituting x = - 3 into (1), gives

- 3 + y = 10 ( add 3 to both sides )

y = 13

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
