Answer:
They aren't equivalent
Step-by-step explanation:
Look at them as simplified fractions
4/18 = 2/9
2/12 = 1/6
If both of these are in their most simplified forms then its not equivalent!
Answer:
radius = arc length / central angle in radians
radius = 4 inches / 5*PI / 12
radius = 4 / 1.308996939 radians
radius = 3.0557749074
radius = 3.0557749074 inches
Step-by-step explanation:
Answer:
a n = -3+(n-1)-30
Step-by-step explanation:
-3 - 30 = -33
-33 - 30 = -63
-63 - 30 = -93
The common difference here is -30. d = -30
The explicit formula is a n = a1 + (n-1)d
Answer:
f (k)
Step-by-step explanation:
2x+4y=16
x-7=-4y
4y=16-2x
<span>4y=16-2(-4y+7)
4y=16+8y-14
-4y=2
-4y/-4=2/-4
<u>y=-0,5</u>
2x=16-4(-0,5)
2x=16+2
2x/2=18/2
<u>x=9
</u>
