Solve the equation 2x-3=15 A)x=6 B)x=9 C)x=24 D)x=36

1 answer:

5 0

To solve the equation, it is necessary to isolate the unknown variable "x" first. This is done as shown below:

2x - 3 = 15

Adding 3 to both sides of the equation:

2x - 3 + 3 = 15 + 3
2x = 18

Dividing 2 from both sides:

2x/2 = 18/2
x = 9

Among the choices, the correct answer is B.

Show all work. What are the zeros of the function?<br> f(x) = 2x^2 − 8x − 10

vivado [14]

(2x² - 8x - 10) ÷ 2 = 0
x² - 4x - 5 = 0
x² + x - 5x - 5 = 0
x(x+1) - 5(x+1) = 0
(x+1)(x-5) = 0
x+1 = 0 or x-5 = 0
x = -1 or x= 5

S = {-1;5}
