First simplify with distribuation 6x-5=5x-15+x
add like terms 6x-5=6x-15
then well you sure this is the correct question
then add 5 to both sides 6x=6x-10
then are you sure this is correct
then sub 6x from both sides so 0 = -10
which it doesn't so this would be false
if you have to find x then well I think you got the wrong question.
Answer:
90.91
Step-by-step explanation:
Answer:
d(t) = -100t
Step-by-step explanation:
The general expression for the linear model is:
Since the submarine already starts at sea level, b=0:
The constant "m" is the rate at which the submarine descends in feet per minute. Considering depth as a negative quantity, m=-100
The linear model that represents the depth of the submarine relative to sea level, in feet, after t minutes is d(t) = -100t.
The vertex form: y = a(x - h)² + k
y = x² - 6x + 7 = x² - 2x · 3 + 3² - 3² + 7 = (x - 3)² - 9 + 7 = (x - 3)² - 2
Answer: y = (x - 3)² - 2
Used: (a - b)² = a² - 2ab + b²
A^2 + b^2=c^2 is the equation
