Answer:
X = -1.4
Step-by-step explanation:
{(5 x -3.4) + 10} = -7
{-17 + 10} = -7
-7 = -7
Answer:
Step-by-step explanation:
The worth of a penny is 1 cent = 1/100 = $0.01
The worth of a nickel is 5 cents = 5/100 = $0.05
Let x represent the number of pennies that she could have. Lucy has some pennies and some nickels. She has a maximum of 15 coins. If lucky has 6.999999999999999, it means that
6.999999999999999 + x ≥ 15
x ≥ 15 - 6.999999999999999
x ≥ 8
If the 15 coins worth a minimum of $0.47combined, it means that
0.05(6.999999999999999) + 0.01x ≤ 0.47
0.35 + 0.01x ≤ 0.47
0.01x ≤ 0.47 - 0.35
0.01x ≤ 0.12
x ≤ 0.12/0.01
x ≤ 12
Therefore, the possible values for the number of pennies that she could have is 8 ≤ x ≤ 12
Answer:
X ints = (-1,0) , (3,0)
Y int = (0, -3)
Minimum (as it infinitely extends positively, but does not go down all the way)
Min point = (1,-4)
Step-by-step explanation:
X/1000=72/125 multiply both sides by 1000
x=72000/125
x=576
So the fraction is 576/1000
