IF J is between C and T, find the value of x and JT. CJ=8x+5, CT=55, and JT=4x+2

just olya [345]

Answer:

Step-by-step explanation:

Given three points J, C and T on a line, if J is between C and T then;

CJ + JT = CT.

Given CJ=8x+5, CT=55, and JT=4x+2, substituting this parameters in the equation above will give;

$(8x+5)+(4x+2)= 55\\8x+4x+5+2 = 55\\12x+7 = 55\\12x = 55-7\\12x = 48\\ x = \frac{48}{12} \\x = 4$

SInce JT = 4x+2

$JT = 4(4)+2\\JT = 16+2\\JT = 18$

What is the value of d? Assume that the line is a tangent to the circle.

motikmotik

We have been given a chord and tangent to a circle. We have been minor arc measure that is equal to $118^{0}$ .

Since we know that angle formed by a secant and tangent of circle is half of the measure of intercepted arc.

$\measuredangle x=\frac{1}{2}m \widehat{ABC}$

We can find intercepted arc by subtracting minor arc measure from 360 degrees because minor and major arcs add up to 360 degrees.

$360^{0}-118^{0}=242^{0}$

Now we will plug given values in our formula,

$d^{0}=\frac{242}{2}=121$

Therefore, the measure of d is 121 degrees.

Answer:

Step-by-step explanation:

$\left\{\begin{array}{ccc}4x-y=-15&\text{multiply both sides by (-2)}\\3x-2y=-10\end{array}\right\\\underline{+\left\{\begin{array}{ccc}-8x+2y=30\\3x-2y=-10\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad\qquad-5x=20\qquad\text{divide both sides by (-5)}\\.\qquad\qquad\boxed{x=-4}\\\\\\\text{Put the value of x to the first equation.}\\\\4(-4)-y=-15\\-16-y=-15\qquad\text{add 16 to both sides}\\-y=1\qquad\text{change the signs}\\\boxed{y=-1}$
