4 (.05) x +( .10)x =180
.20x + .10x = 180
.30x = 180
X= 6
So. 4 times 6 = 24 nickels and 6 dimes = 180 cents
Answer:
an=a1+d(n−1) a n = a 1 + d ( n - 1 )
Step-by-step explanation:
This is an arithmetic sequence since there is a common difference between each term. In this case, adding −5 to the previous term in the sequence gives the next term. In other words, an=a1+d(n−1) a n = a 1 + d ( n - 1 ) .
Answer:
No, because it doesn't pass the vertical line test. There are two y's for every x. Therefore, it is not a function
Answer: Option B, The graph does NOT represent a function
Answer:
x=(-9)
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
(−2/3)(9+x)=0
(−2/3)(9)+(−2/3)(x)=0(Distribute)
−6+−2/3x=0
−2/3x−6=0
Step 2: Add 6 to both sides.
−2/3x−6+6=0+6
−2/3x=6
Step 3: Multiply both sides by 3/(-2).
(3−2)*(−2/3x)=(3−2)*(6)
x=−9
