A jar contains q quarters and d dimes. There are 7 coins in the jar and the total value of the coins is $1.00. Which system of equations can be used to find how many of each type of coin is in the jar? A.0.25q + 0.10d = 1.00
q + d = 7

B.0.10q + 0.25d = 1.00
q + d = 7

C.25q + 10d = 1
q + d = 7

D.0.25q + 0.10d = 7.00
q + d = 1

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

hello! just here for points! though i wish i knew!
