What is the explicit formula for the sequence? -7,-4,-1,2,5

Mathematics

Answer:

y = -7 + 3(n-1)

Step-by-step explanation:

The basic formula for an explicit formula is:

a_{n} = a_{1} + d(n-1)

The first term is clearly -7 and the common difference is 3 because each term is 3 more than the term before it:

a_{n} = -7 + 3(n-1)

an =a1+d(n-1)

a1=-7

d= -4--7=-4+7=3

an =-7+3(n-1)

or

an = -7+ 3n-3

an=-10+3n

What are the properties of the point (2, 0) in this graphed function?
Alex73 [517]

The point (2,0) represents a relative minimum and an x-intercept.

<h3>How to determine the property?</h3>

The missing graphed function is added as an attachment

The point (2,0) means that:

x = 2 and y = 0

On the attached graph, we can see that the graph touches the x-axis at (2,0); this represents the x-intercept

Also, the graph has a minimum at (2,0); this represents the relative minimum

Hence, the point (2,0) represents a relative minimum and an x-intercept.

Solve for y 2x+y-3z=5
Elza [17]

Answer:

<h3>A. y=-2x+3z+25</h3>

Step-by-step explanation:

Isolate the term of x and y from one side of the equation.

<u>To solve:</u>

  • The value of y.

\Longrightarrow: \sf{\sqrt{2x+y-3z}=5}

<h3>2x+y-3z=25</h3>

<u>First, you have to subtract by 2x-3z from both sides.</u>

\Longrightarrow: \sf{2x+y-3z-\left(2x-3z\right)=25-\left(2x-3z\right)}}

<u>Solve.</u>

\Longrightarrow: \boxed{\sf{y=25-2x+3z}}}

  • <u>Therefore, the correct answer is "A. y=-2x+3z+25".</u>

I hope this helps, let me know if you have any questions.
