Solve: 12^x2+5x-4 = 12^2x+6<br> x=2<br>x = -5<br>x=2x=-5<br>no solution​
omeli [17]

Answer:

x=2

Step-by-step explanation:

12x^2+5x-4 = 12x^2+6

Subtract 12x^2 from each side

12^x2-12x^2+5x-4 = 12^2x-12x^2+6

5x-4 = 6

Add 4 to each side

5x-4+4 = 6+4

5x = 10

Divide each side by 5

5x/5 = 10/5

x = 2

Determine the arc length in radians.... need major help please!!!
In-s [12.5K]

If you're supposed to find the measure of the arc:

The minor arc CD has the same measure as the central angle it subtends. In this case, arc CD has measure 50º. In radians, that's

50º * (π/180 rad/º) = 5π/18 rad

If you instead meant to ask about finding the length of the arc CD, recall that arc lengths and their subtended central angles occur in a fixed ratio equal to the ratio of the circle's total circumference to 2π rad. In other words, if <em>L</em> is the length of the minor arc CD, then

<em>L</em> /(5π/18 rad) = 2π (7 cm) / (2π rad)

==>  <em>L</em> = 35π/18 cm

(Notice that arc measure is given radians, while arc length is given in cm, which is why I offer two different answers here.)

Is there a vertical shift? What is it?<br> 2(x+2) – 5<br> I NEED HELP ASAP!!
scoray [572]

Answer:

Yes, there s a vertical shift to the right by 1

Step-by-step explanation:

If you distribute the 2 among the (x+2) you get:

              2x+4-5

Combine like terms:

              2x+1

There fore the line shifts right by one.

Answer:

  • 95°
  • 85°

Step-by-step explanation:

<u>Given angles are consecutive interior angles which sum up to 180°</u>

  • 9x + 14 + 8x + 13 = 180
  • 17x = 180 - 27
  • 17x = 153
  • x = 153/17
  • x = 9

<u>Angles</u>

  • 9x + 14 = 9*9 + 14 = 81 + 14 = 95°
  • 8x + 13 = 85°
