a collection of coins consist of nickels, dimes, and quarters. there are 3 fewer quarters than nickels and six more dimes than quarters. how many of each kind of coin is in the collection if the total value of the collection is $4.35?
Using a system of equations, there are 9, 12 and 15 quarters, nickels and dimes respectively.
Creating a system of equations thus :
n + d + q = 36 - - - (1)n = q + 3 - - - (2).d = q + 6 - - - (3)Substitute for n and q
(q+3) + (q+6) + q = 36
3q + 9 = 36
3q = 36 - 9
q = 27 ÷ 3
q = 9 quarters
n = 9 + 3 = 12 nickels
d = 9 + 6 = 15 dimes
Hence, there are 9, 12 and 15 quarters, nickels and dimes respectively.

write an equation in slope-intercept form when given the information:
slope = 0, goes through the point (-3 , 3)
Answer:
[tex]y=3[/tex]
Step-by-step explanation:
We are given the slope of the line and a point on the line.
So, we can utilize the point-slope form, given by:
[tex]y-y_1=m(x-x_1)[/tex]
Where m is the slope and (x₁, y₁) is a point.
We know that the slope is 0. So, m = 0.
And we will let (-3, 3) be (x₁, y₁). Hence, by subsitution:
[tex]y-(3)=0(x-(-3))[/tex]
Simplify:
[tex]y-3=0[/tex]
We can add 3 to both sides. Hence, our equation is:
[tex]y=3[/tex]
As you would've expect, since it had a slope of 0, it is a horizontal line.
