Answer:
Option D y=3
Step-by-step explanation:
The question in English is
Which of the following functions is a constant function?
we know that
A <u>constant function</u> is a function whose output value is the same for every input value
so
<u><em>Verify each case</em></u>
case A) y=x+1
This is not a constant function, this is a linear equation
Is a function whose output value is different for every input value
case B) y=x+2
This is not a constant function, this is a linear equation
Is a function whose output value is different for every input value
case C) x=y+3
This is not a constant function, this is a linear equation
Is a function whose output value is different for every input value
case D) y=3
This is a constant function
Is a function whose output value is the same for every input value
the question does not present the options, but this
does not interfere with the resolution
Let
a1=-4
a2=-24
a3=-144
a4=-864
a5=?
we know that
a2/a1=-24/-4----> 6-------> a2=6*a1
a3/a2=-144/-24---> 6-----> a3=6*a2
a4/a3=-864/-144---> 6----> a4=6*a3
therefore
a5=6*a4-----> a5=6*(-864)------> a5=-5184
hence
the formula is
an=6*a(n-1)

Answer:
This question is only if 25 points. And you have typed 50 points.
Answer is 16-4-2-1
The answer to your question is 2,600
16 gal = 200 mi
X gal = 350
16/200 = X/350
Cross multiply divide
16(350) = 200(X) > 5600 = 200X
Solve for X
5600/28
X = 28
