Answer:
-3
Step-by-step explanation:
slope = Δy / Δx = -6/2 = -3
Formula Multiply the number by -3/4
The number 48 is 3/4 of 64 but it is negative so the result of -48 should be multiplying 64 by negative 3/4
64x-3/4 =-48
after 48 will be a positive number since (-)x(-)=(+)
So it will be alternating positive and negative
If he is only buying one of each, then his total cost from each store would be:
John's: $23.89 + $15.67 + $9.99 = $49.55
Sam's: $21.35 + $12.45 + $12.99 = $46.79
So, Sam's has the better deal (proof above).
If he has 3 twenty dollar bills, then he has $60.
His change would be:
$60 - $46.79 = $13.21
If he bought two pants from Sam's (the store with the better deal), then his total would be:

(2)($21.35) + $12.45 + $12.99 = $68.14</span>
Option C
The explicit formula for the arithmetic sequence is
<em><u>Solution:</u></em>
Given that the arithmetic sequence is:
3, -3, -9, -15, -21, ...
To find: Explicit formula for the arithmetic sequence
<em><u>The nth term of an arithmetic sequence is given by:</u></em>
Where is nth term of sequence
n is the term's location
is the first term of sequence
d is the common difference between terms
In an arithmetic sequence, the difference between successive terms is constant. This means that we can move from any term to the next one by adding a constant value.
In the given sequence:
3, -3, -9, -15, -21, ...
d = difference between any two terms in sequence
d = -3 - (3) = -6
Substituting the values in above formula,
Thus the explicit formula to find any term in sequence is found
Answer:
He worked 7 hours each day, last week
Step-by-step explanation:
-$420 earned last week
-He worked for 5 days (420 / 5)
-He earns $12 per hour
- How many hours he worked is unknown (x)
Equation
12x = 420/5
12x = 84
x = 7
