Answer:
two solutions
Step-by-step explanation: it cant be no solution because no solution will be a vertical line it can be one solution becuase y=x is a solution and so is y=4
Answer:
x = 10
Step-by-step explanation:
Given
14x - 7 = 133 ( add 7 to both sides )
14x = 140 ( divide both sides by 14 )
x = 10
Answer:
Hence x = y = 2
Step-by-step explanation:
Using the SOH CAH TOA identity
Hypotenuse = 2√2
Opposite = x
theta = 45
Sin theta = opp/hyp
Sin 45 =x/2√2
1/√2 = x/2√2
x = 2√2 * 1/√2
x = 2
To get y we will use the pythagoras theorem;
(2√2)² = x² +y²
(2√2)² = 2²+y²
8 = 4 + y²
y² = 8-4
y² = 4
y = √4
y = 2
Hence x = y = 2
Answer:
Step-by-step explanation:
d = dimes and q = quarters
0.10d + 0.25q > = 4 (thats greater then or equal to)
Answer:
0.0001075
Step-by-step explanation:
The relation between halflife and rate at which it is decaying is given by
now in the above problem halflife is given as 2800 years substituting in the above equation we get the value of rate at which it is decaying to be rate=0.0001075.
