Answer:
There are 32 dimes and 25 quarters.
Step-by-step explanation:
q + d = 57 or q = 57 - d
25q + 10d = 945
substitute first equation into second equation:
25(57 - d) + 10d = 945
1425 - 25d + 10d = 945
-15d = -480
d = -480/-15 = 32
using first equation:
q = 57 - 32 = 25
check using second equation:
25(25) + 10(32) = 945 checks
Answer:
-3
Step-by-step explanation:
The slope of a linear line can be found using the equation:
m=(y2-y1)/(x2-x1)
m=(2 - -6)/(9 - 3)
m=(-4)/(6)
m=(-2/3)
