What is the value of z so that -9 and 9 are both solutions of x^2+z=103?

Z = 22

Step-by-step explanation:

plug 9 into the equation

9^2 + z = 103

81 + z = 103

subtract 81 from both sides

z = 22

do the same with -9

since you are squaring -9 this still equals 81 so the answer is the same.

answer

false

explanation

these practices describe the manner the land use outcome is attained. land management methods implemented by corporations are a mandatory because they are a driver for better land use results economically, socially and environmentally. corporations are required to understand the connection between land use , and land management practices to support sustainable land use policies

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
