Question 557297
On three consecutives passes, a football team gains 5 yards, loses 10 yards and gains 45 yards. What number represents the total net yardage? 
The answer I got was 5-10+45=50
The answer you should have is = 40 yds
----------------------------------------- 
- Solve by using the substitution method. 8x+3y=-42 and x=8-7y
Substitute for "x" and solve for "y":
8(8-7y) + 3y = -42
64-56y + 3y = -42
-53y = -106
y = 2
=============================
Solve for "x":
x = 8-7y
x = 8-7*2 = -6
--------------------------
 
-What is the domain of 
 p(x)=x^2-2x+1
Domain is "All Real Numbers".
---- 
y= (6/5)x+5
Domain is "All Real Numbers".
---- 
Determine if (-1,6) is a solution for 6x-6y=1
Check: 6*-1-6*6 = 1
-6-36 = 1
No, (-1,6) is not a solution.
----------------------------------- 

Find the slope for (3,9) and (7-10)
slope = (9--10)/(3-7) = 19/-4 = -19/4
----------------------------------- 
Find the slope and the y-intercept for f(x)=-2x-3
Slope = -2
y-intercept = -3
----------------------------------- 
Solve 7x not equal to 35 
Divide both sides by 7 to get:
x # 5
