Answer:

x  = ±3/2

Step-by-step explanation:

4x^2 - 9=0

Add 9 to each side

4x^2 -9+9 =0+9

4x^2 =9

Divide each side by 4

4x^2/4 = 9/4

x^2 = 9/4

Take the square root of each side

sqrt(x^2) = ±sqrt(9/4)

x  = ±sqrt(9)/sqrt(4)

x  = ±3/2

The ordered pairs (1, 1) , (2, 16) , (3, 81) , (4, 256) , and ( 5, 625) represent a function. What is a rule that represents thi
Artemon [7]

Answer:

C

Step-by-step explanation:

Note that each of the y- coordinates is the x- coordinate raised to the power of 4.

(1, 1) → y = 1^{4} = 1

(2, 16) → y = 2^{4} = 16

(3, 81) → y = 3^{4} = 81

(4, 256) → y = 4^{4} = 256

(5, 625) → y = 5^{4} = 625

Thus the rule is y = x^{4} → C

The figure below, angle y and angle x form vertical angles. Angle y forms a straight line with the 60° angle and the 70° angle.
Mila [183]

We know angle x=y(vertically opposite angles)

Since 3 angles lie on a straight line,

y+60+70=180 (linear pair)

y+130=180

y=180-130

y=50 degrees
