<span>6x-7y=-84
7y = 6x + 84
y = 6/7(x) + 12</span>
Answer:
Step-by-step explanation:
x=2,x-2=0
x=8
x-8=0
y=(x-2)(x-8)=x²-2x-8x+16=x²-10x+16
=x²-10x+25-25+16
=x²-10x+25-9
y=(x-5)²+9
axis of symmetry is x-5=0 or x=5
Answer:
Step-by-step explanation:
altitude = sqrt(6*8) = 4*sqrt(3)
Use the Pythagorean Theorem to derive x
altitude^2 + 18^2 = x^2
48 + 18^2 = x^2
x^2 = 342
x = 3*sqrt(38)
x = 18.49
Answer: 125,000 BTUs
Step-by-step explanation:
Hi, to answer this question we have to apply proportions:
A fuel tank has a volume of 36 gallons. When filled with biodiesel, it provides 4,500,000 BTUs
So, the proportion is:
36 gallons / 4,500,000 BTUs
For 1 gallon
1 gallon / x BTUs
36/4,500,000 = 1/x
Solving for x:
x = 1 / (36/4,500,000)
x = 125,000 BTUs
