F(x)= x - 10
f(-7) = - 7 - 10
f(-7) = - 17
Y=-2/3x+-4. Here is the original equation for a line. (M is slope and b is y-intercept((the point which the line goes through the Y-axis))) y=Mx+b
Answer:
2 pieces
Step-by-step explanation:
Given
Required
Calculate the number of pieces
To do this, we have to divide the length of the wood by the length of each piece.
Represent this with x
Convert mixed numbers to improper fraction
Change division to multiplication

So what you want to find is: what number times 120% is $324.00. (IT is 120% percent because it is the original <em>plus</em> the new percent) Simply set it up like so:
SN *120% = $324.00
Now turn the percent into a decimal:
SN * 1.20 = $324.00
Now divide $324.00 by 1.20
SN = $270
The original value of the basketball player's autograph was 270 dollars!
Hope that helps!
