Let n be the number of lbs of nuts.
Let r be the number of lbs of raisins.
9n + 3r = 60 * 5 = 300 .............(1)
n + r = 60
n = 60 - r ...............(2)
Plugging the expression for n in (2) into (1) we get:
9(60 - r) + 3r = 300
which expands to:
540 - 9r + 3r = 300 .............(3)
Simplifying and rearranging (3) we get:
-6r = -240
Therefore r, the weight of raisins = 40 lbs
and the weight of nuts is 60 - 40 = 20 lbs
Answer:
A) x+5
B) 121
Step-by-step explanation:
A) If Tim is 5 pounds heavier than Amy, an equation for this situation can be modeled by x+5, where Amy is <em>x </em>pounds.
B) If Tim is 126 pounds, then Amy's weight is 126-5=121 pounds.
Step-by-step explanation:
x y
−3 0
−1 −2
2 −5
6 −9 is a nonlinear
because when you plot the points given x=-3 y=0 and x=-1 y=-2 are found in the 3rd quadrant and the rest are found in the 4th quadrant.
which will not make the points linear
Hope this will help
Insert x = 100 and x = 200 in the function
f(100) = 20,000 - 40*100
= 20,000 - 4000
= 16,000
f(2)) = 20,000 - 8,000 = 12,000
So its choice C , All reals between 12,000 and 16,000 inclusive.
