I am not going to answer each but here is a general answer.
y is total price and x is number of kids
Sandy's equation would be y= 10+5x
Kimmi's equation would be y= 25
For them to equal we would have 25=10+5x
Simplify
5x=15
x=3
So for them to be equal, Sandy should have 3 kids.
So if someone has 5 children then he should choose Kimmi
Answer:
a(n)=1+(n-1)(-3)
Step-by-step explanation:
Notice there's a common difference of d=-3.
If we use the formula a(n)=a1+(n-1)d to find the nth term given the first term and the common difference, we will see that the function that describes the arithmetic sequence as a(n)=1+(n-1)(-3)
Answer:
y = 4x + 48
Step-by-step explanation:
Slope intercept form: y = mx + b
y - 8 = 4x + 40
y = 4x + 48
The answer is 1 no solution
