Answer:
19 nickels and 5 pennies
Step-by-step explanation:
Let x nickels and y pennies
100 = 5x + y
x + y = 24
y = 24 - x
100 = 5x + 24 - x
4x = 76
x = 19
y = 24 - x = 24 - 19 = 5

Answer:
By doubling each day
Step-by-step explanation:
Jay is increasing daily a fixed amount of pennies to his collection. That's an arithmetic series, because to obtain the next term you have to do an addition.
To get a geometric series or progression you have to find the next term through multiplication.
So, if he wants to convert his series into a geometric series, he'd have to double his contribution to his collection each day (as an example).
Answer:
D. (x+2)(-8x+70)
Step-by-step explanation:
-8x^2+54x+140
Factor out -2
-2(4x^2+27x+70)
Factor
-2(x+2)(4x-35)
Option D is the same answer if we multiply -2 in the second term
(x+2) (-8x+70)
