Solve for x

Mathematics
1 answer:
iren2701 [21]3 years ago
3 0

Answer:

2

Step-by-step explanation:

  • ST and SU are tangents to the \odot L from the point S to the points T and U respectively.
  • Measures of the tangents drawn from external point to a circle are equal.
  • \therefore ST = SU
  • \therefore 7x - 3= 5x+1
  • \therefore 7x - 5x=3+1
  • \therefore 2x=4
  • \therefore x=\frac{4}{2}
  • \therefore x={2}

I need help thanks in advance
sergij07 [2.7K]

Answer:

Step-by-step explanation:

The rule is if 2 chords intersect inside a circle, then the measure of the angle formed is one half the um of the measure of the arcs intercepted by the angle and its vertical angle. In other words, angle TSU = 1/2(arc TU + arc MV):

angle TSU = 1/2(90 + 80) and

angle TSU = 1/2(170) and

angle TSU = 85

Helppppp me find a equation for this lol
LUCKY_DIMON [66]

Answer: One POSSIBLE answer is (0,9)

Step-by-step explanation: This may look hard but it's actually super easy. All you have to do is substitute a value for x and see what you get as the y value. The first thing I would do is rearrange the equation so that the equation is in the format y = something. So the first thing you should do is subtract 6x from both sides of the equation and you should get -y=-6x+9. Right now, the y is being multiplied by -1, and to undo multiplication, you have to divide. So divide both sides of the equation by -1 (remember, what you do on one side of the equation, YOU HAVE TO DO THE SAME THING ON THE OTHER SIDE). So your new equation would be y=6x-9. Then, all you have to do is substitute a value for x and see what you get for y (x is basically the input and whatever you get for y is the output). S for example, let's say that x=0. So substitute a 0 in the equation wherever you see an x. So in this case, you would get y=(6x0)+9. Then you just simplify. So 6x0 is 0 and 0+9=9 So y=9

TO RECAP: Rearrange the equation so that the equation is in the format y = something. Then, input any number for x, and whatever you get for y is what you put in the brackets as your y value for your final answer.

Hope this helps!

Factor 5a^2-30a+45, and 2x^5+x^4-2x-1.
Mrrafil [7]

Step-by-step explanation:

{5a}^{2}  - 30a + 45

5( {a}^{2}  - 6a + 9)

5(a-3)(a-3)

5(a-3)^2

{2x}^{5}  +  {x}^{4}  - 2x - 1

X^4(2x+1) - (2x+1)

(x^4-1)(2x+1)

(x^2-1)(x^2+1)(2x+1)

(x-1)(x-1)(x^2+1)(2x+1)
