Here the given expression is

y =(\frac{3}{4})^x

We need to find the value of y when x =3 . So we substitute the value of x in the given expression.

y =(\frac{3}{4})^3 = \frac{27}{64} =0.4

So when x=3, y=0.4 and that's the required answer.

Use an inverse matrix to solve for the system of equations.
IrinaK [193]

Answer:

(-1, 7, 2)

Step-by-step explanation:

we suppose that ax + by + cz = d for the matrix

D = det [ 0    4     7] = 100

              -6   0    -2

               1    2     8

Dx= det [ 14    4     7] = - 100

               10   0    -2

               -3    2     8

Dy= det [ 0    14    7] = 700

               -6   10    -2

                1    -3    8

Dz = det [ 0    4    14] = 200

               -6   0     10

                1    2     -3

So the solution is:

x = Dx/D = -1, y = Dy/D= 7, z =Dz/D = 2

(-1, 7, 2)

have a good day!
