Given the system of equations
2x + 5y = 4
3x − 8y = −25
a. show how this system can be written as a statement about a linear transformation of the form ll= b,
with x =
xy
and b = 4
−25

b. determine whether l has an inverse. if it does, compute l−1b, and verify that the coordinates represent the
solution to the system of equations

step-by-step explanation:

the true ones are a b and d

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a

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
