Answer: n + d = 30
0.05n + 0.10d = 2.20
^^ ur system of equations
Step-by-step explanation:
Y=money spent
X=games played
For the winter festival, it would be y=2x+20
For the fall festival, it would be y=5x+5
Answer:
Note that i= √-1 so you say √-25=√25i so the answer is 5i
First find the slope. m=(y2-y1)/(x2-x1)
m=(4225-1990)/(5-2)=745,
m is the slope, this represents the amount of money earned each month that the business operates.
so far we have:
y=745x+b, using any point we can solve for b, I'll use (2,1990)
1990=745(2)+b
1990=1490+b
500=b
b is the y-intercept which is $500, it represents the amount of moeny that the business started with.
Answer:
Step-by-step explanation:
Tony's cat weighs c pounds. This means that the cat currently weighs c pounds.
Three months from know, the cat's weight is expected to increase by 12.5%. This means that in three months time, the weight of the cat is expected to be the sum of its current rate × 12.5 % of its current rate. It becomes
c + 12.5/100 × c = c + 0.125c
= 1.125c
So the two expressions that represent the cat's weight in three months would be
1) three months from now, the cat's weight will increase by 0.125c
2) three months from now, the new weight of the cat will be 1.125c
