Answer: 1 club - Club 2
Step-by-step explanation:
You can find the monthly rates by deducting the cost at 12 months from the cost at 24 months and dividing it by 12.
Club 1 Club 2 Club 3
= (432 - 216) / 12 = (390 - 210) / 12 = (504 - 252) / 12
= $18 = $15 = $21
Multiply these rates by 6 months and any club total cost at 6 month that differs from your answer has a joining fee.
Club 1; Club 2; Club 3
= 18 * 6 = 15 * 6 = 21 * 6
= $108 = $90 = $126
<em>Same as total cost at </em><u><em> Joining fee of $30</em></u><em>; </em> <em>No joining fee as </em>
<em>6 months so no joining 120 - 90 = $30 this is the same </em>
<em>fee. as total cost at 6 </em>
<em> months.</em>
Answer:
y=2/3x
Step-by-step explanation:
y=mx+b
m is the slope
b is the y-intercept
y=2/3x
here the y-intercept is not written in the equation because it's 0
One way to find out is to subsiute the points and find which ones are true
the points are (3,2) and (-2,-1)
subsiute 3 for x and 2 for y, then -2 for x and -1 for y
y-3=3/5(x-2)
2-3=3/5(3-2)
-1=3/5(1)
-3=3/5 false
-3x+5y=1
-3(3)+5(2)=1
-9+10=1
correct
try the other
-3(-2)+5(-1)=1
6+-5=1
true
one answe ris B
3/5x+1/5
this is incompleteso I can't solve it
maybe it was supposed to be 3/5x+1/5=y, but I don't know
y+1=3/5(x+1)
2+1=3/5(3+1)
3=3/5(4)
3=12/5
false
the answe ris B (maybe C but I con't know)
Answer:
Step-by-step explanation:
H=7+30t-16t²
20=-16t²+30t+7
0=-16t²+30t-13
T=(-30±√(900-4(16)13))/-32
T=0.68 s or T=1.2 s
