4x+5=13
Start by subtracting 5 from both sides:
4x+5-5=13-5
4x=8
Divide both sides by 4 to isolate x
x=2
R<5
r has to be less than 5, now doesn't it
Answer:
(4,0)
Step-by-step explanation:
The zeros of the quadratic functions are where it crosses the x axis
It crosses at x=-2 and x=4
( -2,0) and (4,0)
Answer:
120°
Step-by-step explanation:
The arc ABC is twice that of the angle created at D. This is the central angle theorem extension.
So we can say that arc ABC = 2* 120 = 240
<em>We know total circle angle is 360 degrees so, arc ADC + arc ABC = 360</em>
<em />
<em>Hence,</em>
<em>arc ADC + 240 = 360</em>
<em>arc ADC = 360 - 240 = 120</em>
