Solve for x ~<br><img src="https://tex.z-dn.net/?f=3%20%5C%3A%20%2814%20-%205x%29%20%3D16%20-%20%2012x" id="TexFormula1" title="

$3(14 - 5x) = 16 - 12x$

Distribute 3 throught the parentheses

$42 - 15x = 16-12x$

Move the variable to the left-hand side and change its sign

$42 - 15x + 12x = 16$

Move the constant to the right-hand side and change its sign

$- 15x+12x=16 - 42$

Collect like terms

$- 3x = - 26$

Divide both sides of the equation by -3

$\boxed{x = \frac{26}{3} }$

Point O is the center of the circle. What is the value of X? <br> Answer options: 24, 15, 27, 20

Answer: FIRST OPTION

Step-by-step explanation:

To solve this problem you must apply the Intersecting Secant-Tangent Theorem. By definition, when a secant line and a tangent lline and a secant segment are drawn to a circle from an exterior point:

$(Tangent\ line)^2=(Secant\ line)(External\ Secant\ line)$

The total measure of the secant shown is:

$18+Diameter$

If the radius is 7, then the diameter is:

$D=7*2=14$

Therefore:

$Secant\ line=18+14=32$

You also know that:

$External\ Secant\ line=18\\Tangent\ line=x$

Keeping the above on mind, you can substitute values and solve for x:

$x^{2}=32*18$

$x=\sqrt{576}\\x=24$

PLEASE HELP!!!!!!!!

Flura [38]

the answer is A ,when x=0,g(x)is-1,so when u add x into the g(x),which is given below,u can find C,D,E,g(x) is no equal to -1,when you add x=1 into g(x)(A,B),you can find g(x) of B is 0,which is no equal the answer giving above(g(x)=2),but A is all right.
