I WILL GIVE 20 POINTS TO THOSE WHO ANSWER THIS QUESTION RIGHT NOOOO SCAMS AND EXPLAIN WHY THAT IS THE ANSWER
Firdavs [7]
2x+20=58 then your would subtract 20 from 58 which would turn into 38 and your would divide 38/2 it would be 19 so the answer is x=19 if I’m not mistaken this is correct hope this helps

Quadrilateral STWR is inscribed inside a circle as shown below. Write a proof showing that angles T and R are supplementary.
AlladinOne [14]

Observe the given figure.

Here, angle T and R are the inscribed angles.

And sum of inscribed angles is half of measure of intercepted arcs.

Since, the measure of intercepted arcs is 360 degrees.

Therefore, \angle T + \angle R = \frac{1}{2} \times 360 ^{\circ}

\angle T + \angle R = 180 ^{\circ}

Hence, the sum of the two angles is 180 degrees.

Therefore, these are the supplementary angles.

Therefore, angle T and angle R are supplementary angles.

Hence, proved.

F(x)=−2x+16<br> g(x)=4x+10<br> please give me the intersection points
vagabundo [1.1K]

Answer:

  • (1, 14)

Step-by-step explanation:

The intersection is when both functions have same coordinates

  • f(x) = g(x)

Substitute to get

  • - 2x + 16 = 4x + 10
  • 4x + 2x = 16 - 10
  • 6x = 6
  • x = 1

The y- coordinate is

  • y = - 2(1) + 16 = -2 + 16 = 14

So the intersection point is (1, 14)

Answer:

○ C. The lines are perpendicular.

Step-by-step explanation:

In order for equations to be perpendicular, their <em>rate of changes</em> [<em>slopes</em>] must be OPPOSITE <em>MULTIPLICATIVE</em><em> </em><em>INVERSES</em>, which in this case is so:

− to +}

> OPPOSITE
