Answer:
Rate of change = -30
Initial value = 400
Step-by-step explanation:
Write the equation of the linear function representing this situation. Let
x = number of weeks Gandalf is spending money
y = amount of quibbles left in his account.
Gandalf has 400 quibbles in his account. This means, 
is the initial value of quibbles Gandalf had in his account
He spends 30 quibbles each week, this means, that he spends 30x quibbles in x weeks and the amount left in his account is
Therefore, the slope is 
and this is the rate of change (negative because the amount of money in his account decreases each week)
Answer:
y=1/2x-5
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(1-(-2))/(12-6)
m=(1+2)/6
m=3/6
simplify
m=1/2
----------------------
y-y1=m(x-x1)
y-(-2)=1/2(x-6)
y+2=1/2(x-6)
y=1/2x-6/2-2
y=1/2x-3-2
y=1/2x-5
Answer:
Step-by-step explanation:
81= 3 times k. K equals 27
4x-12 = 18. X is 5
4x-3=5. X is 2
4x-2=38. Answer is C

Answer:
The length of the remaining wire is 53.8 centimeters
Step-by-step explanation:
Let us solve the question
∵ Cory has 66.92 centimeters of wire
∵ He uses 2 pieces of the wire, each piece he uses is 6.58 cm long
→ Find the length of the two pieces he uses
∵ He uses = 2 × 6.58
∴ He uses = 13.16 cm
∴ The length of wire he uses is 13.16 cm
→ The length of the remaining = the total length - the length he uses
∵ The length of the remaining = 66.92 - 13.16
∴ The length of the remaining = 53.76 cm
→ Round it to the nearest tenth of a centimeter
∴ The length of the remaining = 53.8 centimeters
∴ The length of the remaining wire is 53.8 centimeters
