Solve the following equation algebraically: - 16 = 16 x^2
How many solutions does this equation have? Explain.
a. -1 = x^2; One solution because only -1 will satisfy the equation.
b. -1 = x^2; No real solution because there is no real number that, when squared, produces -1.
c. 1 = x^2; Two solutions because the square root of 1 is positive 1 and negative 1.
d. 1 = -x^2; One solution because only -1 will satisfy the equation.

i believe the answer is d.

hope it you! : d

i think 5 miles per hour

step-by-step explanation:

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
