What value of x satisfies the equation x2 34=74?

1 answer:

3 0

X^2+34=74
minus 34 from both sides
x^2=40
sqrt both sides
x=+/-√40
x=+/-2√10

the values 2√10 and -2√10 are soltuions for x

Answer:

Step-by-step explanation:

note that (f - g) = f(x) - g(x)

f(x) - g(x) = 3x² + 1 - (1 - x) = 3x² + 1 - 1 + x = 3x² + x

To evaluate (f - g)(2) substitute x = 2 into f(x) - g(x)

(f - g)(2) = 3(2)² + 2 = (3 × 4) + 2 = 12 + 2 = 14

I guess the function is a parabola with vertex at (0,0) and opens down so the range is (-infinity, 0].

3 · t - 12 = 40

3t - 12 = 40 |add 12 to both sides

3t = 52 |divide both sides by 3

t = 52/3

t = 17 1/3
