Answer:
The least number of stamps required is 
Step-by-step explanation:
Let the number of 
cent stamps be 
and 
cent stamps be 
We have
The minimum number is obtained when more cent stamps are used
Here cannot be greater than 
since 
Substitute 
Not possible since is not a fraction
Substitute 
Not possible since is not a fraction
Substitute 
Possible
Hence minimum number of stamps is
Let
x = the number of shorts bought
y = the number of t-shirts bought
A pair of shorts costs $16 and a t-shirt costs $10. Brandom has $100 to spend.
Therefore
16x + 10y ≤ 100
This may be written as
y ≤ - 1.6x + 10 (1)
Brandon wants at least 2 pairs of shorts. Therefore
x ≥ 2 (2)
Graph the equations y = -1.6x + 10 and x = 2.
The shaded region satisfies both inequalities.
Answer:
Two possible solutions are
(a) 3 pairs of shorts and 4 t-shirts,
(b) 4 pairs of shorts and 2 t-shirts.

Answer:
x=−2 or x=4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x2−2x−3=5
Step 2: Subtract 5 from both sides.
x2−2x−3−5=5−5
x2−2x−8=0
Step 3: Factor left side of equation.
(x+2)(x−4)=0
Step 4: Set factors equal to 0.
x+2=0 or x−4=0
x=−2 or x=4
Answer:
Explanation:
first term, a₁ = 1
difference between the terms: -3
- used geometric formula :
<u>where "a₁ is first term" and "r refers to common difference"</u>
- formula for this nth term:
