For x-intercepts, you plug 0 for y and solve for x, and vice versa for y-intercepts.
X: 2X+4(0)= 12
2x= 12
12/2= 6 so the x intercept is 6.
Y: 2(0)+4Y=12
4y= 12
12/4= 3 so the y intercept is 3.
Your answer is B. <span>x-intercept: 6; y-intercept: 3</span>
Arc length = angle*radius
Degrees to radians: multiply by pi/180
Arc length = (pi/180*6)*6 = 36/180*pi = pi/5.
The answer is D.
Answer:
She is at least 51. She could be older.
Answer:
131 minutes, an = 15 + (n - 1)(4)
Step-by-step explanation:
each time she is increasing by 4 minutes
we can write this equation like this since we have the difference and the first part:
an = 15 + (n - 1)(4)
note
"an" (or ace of n)'s n is in subscript and is written just like a superscript but on the bottom
we can plug in this equation to find ace of 30 (a30)
15 + (30 - 1)(4)
15 + 29*4
116 + 15
a30 = 131
