I believe midpoint would be always. If someone else answers can I have brainliest? It will give you points back
Answer:
108
Step-by-step explanation:
128x-32-3x-54+x+2=0
128x-3x+x+2-32-54=0
126x-84=0
126x=84
x=2/3
3000+.300+.009 I think but I'm not sure
(3,52)(7,108)
slope = (108 - 52) / (7 - 3) = 56/4 = 14
y = mx + b
slope(m) = 14
(3,52)...x = 3 and y = 52
sub and find b, the y int (the original amount of cards)
52 = 3(14) + b
52 = 42 + b
52 - 42 = b
10 = b
so ur equation is y = 14x + 10....with x being the number of years and y being the total cards. <== ur equation is y = 14x + 10
He started with 10 cards....and has been adding 14 cards every year.
so after 10 years...
y = 14(10) + 10
y = 140 + 10
y = 150 <== after 10 years, he will have 150 cards
