Answer:

  • So we know that C= 2×pi×r
  • Say the r of the first circle is 1 then C= 2pi
  • Now its dilated by a scale factor of 2 so the r=2, so the C=4pi
  • We notice <em>the</em><em> </em><em>circumference</em><em> </em><em>doubles</em><em>.</em>

The phone company Ringular has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount of mon
ivanzaharov [21]

Answer:

The slope is $0.35/min and it gives the cost per minute of the phone used.

Step-by-step explanation:

We can model this situation with a linear equation of the form

y =mx+b

where y is monthly cost, x is the number of minutes, b is the flat monthly fee, and m is the slope of the equation, or in our case, the amount of money charged per minute.

The slope m is

m= \dfrac{\$372.5-\$131}{990min-300min}

m = \$0.35/min,

in other words, the phone company charges $0.5 per minute.

With the slope in hand, the linear equation becomes

y =0.35x+b,

and we can find the monthly fee b from that fact that for 300 minutes the cost is $131:

\$131 = 0.35(300min) +b

b = \%26.

Therefore,

y = 0.35x+26

where the slope if the equation give the cost per minute of the phone used.

C) x<8 and x>10
c) all real Numbers (multiply the -2 to the parenthesis and you get the same equation on both sides which means all real numbers)
C) x is greater than or equal to -3 (solid circle with the line towards positive.)
A) 24 ( distribute then subtract p from both sides)
B) d-12 \geq 51; d \geq 63
