Use the quadratic formula to solve 5x=6x^2-3, what are the values of x?

1 answer:

8 0

5x= 6x^2 -3
6x^2 -5x -3
a = 6
b = -5
c = -3

x = [-b +- sq root(b^2 -4ac)] / 2a
x = [--5 +- sq root (25 -(4*6*-3)] / 12
x = [5 +- sq root (25 + 72)] / 12
x = [5 + sq root (97)] / 12
x = 5 +- 9.84886] / 12
x1 = 1.237405 
x2 = -0.404072

What digit makes each number divisible by nine? _7,302

Alborosie

Answer:

Not completely sure but hopefully these will help.

Step-by-step explanation:

I'm kind of confused what you're asking for. If you could clarify that would be great. If you're trying to make it divisible by 9, you can either do 3, 6 or 9. If you want the first two digits: 2,5,8. Please clarify so I can help

Answer:

The answer to your question is AC = 9.9

Step-by-step explanation:

To solve this problem use trigonometric functions. The trigonometric function that relates the hypotenuse and the adjacent side is cosine.

cos α = $\frac{adjacent side}{hypotenuse}$

Solve for hypotenuse

$hypotenuse = \frac{adjacent side}{cos\alpha }$

Substitution

hypotenuse = $\frac{9}{cos 24}$

Simplification and result

hypotenuse = 9.85

Y=1/3x+4 going through the point (9,-2)

Art [367]

Substitute x=9 and y=-2 into equation,
Left hand side=-2
Right hand side=1/3(9)+4= 3+4=7

Because LHS doesn’t = with RHS, the point (9,-2) doesn’t satisfy with the equation

Therefore the point doesn’t go through y=1/3x +4.
