Which algebraic expression represents the phrase "the quotient of negative eight and the sum of a number and three"
iVinArrow [24]

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.

Write the equation of the line with a slope of 1/5 that passes through the point (20,5)
kolbaska11 [484]

Answer:

y =  \frac{1}{5} x + 1

Step-by-step explanation:

the general equation of a line is y=mx+c

because the slop is 1/5, the equation of this line would be

y =  \frac{1}{5} x + c

with the coordinates (20,5) , take 20=x and 5=y

and substitute these values into the equation above.

you should get:

5= 4 + c

so c = 1

therefore, the equation of the line is:

y =  \frac{1}{5} x + 1

Angle DEF is a right triangle. If FE = 12 and DE = 5, find DF.
Usimov [2.4K]

c^2=a^2+b^2

c^2 = 12^2 + 5^2

C^2 = 144 +25

C^2 = 169

c=13

DF = 13
