Answer:
y=2x + 2
Step-by-step explanation:
2 is the slope and 2 is also the y-intercept
y = mx + b
20% of 60 is 12
60/300 = 20%
The friend is incorrect because that is 20% of 300 not 60
About 11% - I first subtracted 250 from 282, to get 32. I then did 32/282 to get .11.... You round that out to about 11%
So what they are saying is the sum of 2x +13=75
Therefore we can just solve for 2x, our unknown value.
2x+13=75 now subtract 13 and divide by 2 from both sides of equation to not change the equation
x+13-13=75-13
This leaves us with
x=(75-13)/2=31 therefore x=31 or our unknown value is 31.
I hope this helped. Any questions please just ask. Thank you.
