Answer:
It would be y=3(x+2).
Step-by-step explanation:
(This is the explanation you write.)
If you simplify the equation it is y=3x+6. For line A the y-intercept is 6 and the slope is 3.
Youre finding 9.75% of 519 you know its going to be near 50 dollars
your answer is 50.695125
or 50.70$ tax
519.95+50.7 = 570.65$ total
Well,
26.50
In this case, the hundredths place is the 0.
Since there are no more digits after that, 26.50 must already be rounded to the nearest hundredth.
26.50 is the final answer.
Given
gas prices are now $3.75 and it up 10% from 6 months ago.
Find out how much were gas prices 6 months ago.
To proof
gas prices now = $3.75
let the gas price 6 month ago = x
gas price now is rise up 10% from 6 months ago
First write 10% in simpler form

= 0.1
Now the equation becomes
0.1x + x = 3.75
1.1x = 3.75

x = 3.41 (approx)
Thus gas prices 6 months ago be $ 3.41 (approx )
Hence proved
Answer:
x = 12
Step-by-step explanation:
5x - 30 = 2x + 6
3x = 36
x = 12
