PLEASE HELP ME !!! An apparel company uses a trucking service to deliver products from its warehouse to its retail outlets. For
nexus9112 [7]

Let distance between warehouse and retail outlets be x miles.

We are told that for a one-way trip, the trucking company charges a flat rate of $250 per truck, plus $1.25 for every mile driven. The apparel company has a budget of less than $950 per trip.

Upon multiplying 1.25 by x we will get delivering charges for x miles as 1.25*x. Total delivery charges also include $250 per one-way trip, therefore, 250 will be our constant.

Our total delivery charges for x miles will be,

1.25\cdot x+250    

The apparel company should service those outlets for whom delivery cost will be less than $950.

1.25\cdot x+250

Therefore, an inequality representing apparel company's profit will be 1.25\cdot x+250.

The sum of a number and 24 times its reciprocal is 11. Find the numbers
Darina [25.2K]
X+24*(1/x)=11
x+24/x=11
x²+24=11x
x²-11x+24=0
(x+3)(x-8)=0
x=-3, x=8
checking : 8+24*(1/8)=11, 8+3=11 correct
-3+24*(1/-3)=-3-8=-11 incorrect
number is 8, reciprocal is 1/8

I am supposed to simplify 1/a-b - 1/b-a
Andre45 [30]

Answer:

see explanation

Step-by-step explanation:

Given

\frac{1}{a-b} - \frac{1}{b-a}

Before subtracting the fractions, we require them to have common denominator.

Multiply the numerator/denominator of the second fraction by - 1

\frac{1}{b-a} × \frac{-1}{-1} = \frac{-1}{a-b}

We now have

\frac{1}{a-b} - \frac{-1}{a-b} ← common denominators

= \frac{1}{a-b} + \frac{1}{a-b}

= \frac{1+1}{a-b}

= \frac{2}{a-b}

ILLLLLmark brainliest plssssssss heeeelpppp
exis [7]

Answer:

a) (x+2)^2-2

Step-by-step explanation:

write in form of x^2+2ax+a^2

2a=4

a=2

so

x^2+4x+2^2

we will now convert into the form:

x^2+2ax+a^2=(x+a)^2

substitute the values:

x^2+4x+2^2=(x+2)^2

(x+2)^2-2+2^2

(x+2)^2-2
