Answer:
800-80w.
800-80(2)=800-160=640 left in 2 weeks.
800-80(3)=800-240=560
800-80(5)=800-400=400
800-80(7)=800-560=240
800-80(10)= 0. She has 10 weeks until all of her money is gone
Function: 800-80w
Range: 460
Answer:
k = 11
Step-by-step explanation:
What the factor theorem is telling us is that if x + 1 is a factor of 2x - kx²-8x + 5 then when x = - 1 is put into the equation, the result will be 0. That's because x +1 = 0 when x = - 1
f(-1) = 2(-1) - k(-1)^2 - 8(-1) + 5
f(-1) = -2 - k(1) + 8 + 5 = 0
-k*(1) + 11 = 0
-k = -11
k = 11
1st =13
2nd = 13- -5 = 13+5 =18
3rd = 18 - -5 = 18+5 =23
4th = 23 - -5 = 23+5 = 28
<span>Part A. How many total yards did Ed run in the first 3 football games.
</span>total yards Ed = 157 + 309 + 172 = 638
<span>Part B. How many more total running yards did Rico have than Ed after the first 3 games of the season?
</span>total yards Rico = 3*total yards Ed = 3*638 = 1914
so Rico has more yards than Ed, 1914 - 638 = 1276, that is, Rico has 1276 more yards than Ed after the 3 first games
