It is 5
2x2 -4x +6-1= 0 is the standard form
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
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.)
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:
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°
