Answer:

\dfrac{-8}{x+3}

Step-by-step explanation:

We need to find an algebraic expression for the given statement i.e. "the quotient of negative eight and the sum of a number and three".

Let the number be x. Quotient means to divide. It means we need to divide -8 and the sum of x and 3.

So, we can write it as follows :

\dfrac{-8}{x+3}

Hence, this is the required solution.

Water runs from a pump at a rate of 0.5 gallons per minute. At this rate, how long would it take to fill a tub with a 150-gallon
lutik1710 [3]

Answer:

300 min or 5 hours

Step-by-step explanation:

so if it pumps 0.5 gallons per minute than in 2 minutes it would pump 1 whole gallon so with that we know 1gallon=2 minutes.

so with that we multipy both sides by 150 which will be 150 galons=300 minutes or 5 hours

How can you change the equation y = 2x + 3 to function notation?
qwelly [4]

Answer:

f(x)=2x+3

Step-by-step explanation:

The first thing that would need to be done is solving for y. This problem has already done this. The next step is to exchange y for f(x)

That is all. This would mean that the function notation for the equation would be: f(x)=2x+3

What are the center and radius f the circle with equation xthe power of 2 +y power of 2 -4x -6y +8=0
Dovator [93]
<span>x² +y² -4x -6y +8=0
(x² -4x) +(y² -6y) = -8
We are going to complete square for x and y,
it should look like a²+2ab+b² = (a +b)², or </span>a²-2ab+b² = (a -b)²,
<span>
(x²-2*2x+2²) -2² + (y²-2*3y +3²)-3²=- 8
(x-2)²+(y-3)²-4-9=-8
</span>(x-2)²+(y-3)²=-8+13
(x-2)²+(y-3)²=5

Formula a circle (x-h)²+(y-k)²=R², where vertex has coordinates (h, k) 

So , for our circle  vertex (2,3) and radius = </span>√5<span>

From their location in the diagram, what are two possible values for m and n?
yarga [219]
M=6/5 and n = sqrt(2), is rational (but not an integer) and n is irrational.

The case with n = sqrt(9)=3, is not a solution. The case with m=4pi neither.

The last case is m = 6/2=3, integer, so neither works.

So, it is the one with m=6/5 and sqrt(2)
