The midpoint of AB is M(-4,0). If the coordinates of A are (-6,4), what are the coordinates of B?

Answers

Answer 1

Answer:

Answer:

B(-2,-4)

Step-by-step explanation:

Let coordinates of B be (x,y)

$( ( - 6+ x)/(2) . (4 + y)/(2) ) = ( - 4.0) \n x = 2( - 4) + 6 \n x = - 2 \n \n y = 2(0) - 4 \n y = - 4$

Blue Skies Equipment Company uses the aging approach to estimate bad debt expense at the end of each accounting year. Credit sales occur frequently on terms n/60. The balance of each account receivable is aged on the basis of three time periods as follows: (1) not yet due, (2) up to one year past due, and (3) more than one year past due. Experience has shown that for each age group, the average loss rate on the amount of the receivable at year-end due to uncollectibility is (a) 3 percent, (b) 9 percent, and (c) 28 percent, respectively. At December 31, 2019 (end of the current accounting year), the Accounts Receivable balance was $48,700 and the Allowance for Doubtful Accounts balance was $920 (credit). In determining which accounts have been paid, the company applies collections to the oldest sales first. To simplify, only five customer accounts are used; the details of each on December 31, 2019, follow:

Solve –5√ x = –15.

A. x = –7
B. x = –9
C. x = 7
D. x = 9

Answers

Answer:

Option (d) is correct.

$x=9$

Step-by-step explanation:

Given : expression $-5√(x)=-15$

We have to solve for x.

Consider the given expression $-5√(x)=-15$

Divide both side by -5, we have,

$√(x)=(-15)/(-5)$

Simplify, we have,

$√(x)=3$

Squaring both side, we get,

$(√(x))^2=3^2$

Simplify, we get,

$x=9$

Thus, Option (d) is correct.

-5√x = -15
-5 -5
√x = 3
x = 9

The length and a quarter of the width of a rectangle add up to 7 in, while the length and the width add up to 10 in. What are the rectangle's length and width?

Answers

The length of rectangle is 6 inches and width is 4 inches.

Step-by-step explanation:

Let,

l be the length of rectangle

w be the width of rectangle.

Quarter means $(1)/(4)$ .

According to given statement;

$l+(1)/(4)w=7\nl+0.25w=7\ \ \ Eqn\ 1$

l+w = 10 Eqn 2

Subtracting Eqn 1 from Eqn 2

$(l+w)-(l+0.25w)=10-7\nl+w-l-0.25w=3\n0.75w=3$

Dividing both sides by 0.75

$(0.75w)/(0.075)=(3)/(0.75)\nw=4$

Putting w=4 in Eqn 2

$l+4=10\nl=10-4\nl=6$

The length of rectangle is 6 inches and width is 4 inches.

A phone company charges $25 per month, plus an installation fee of $50. If you have paid the phone company $375, how many months have you had the phone?

Answers

The installation fee is a one time thing so you do 375-50. and then you do 325/25 to get 13 so the answer is 13 months

Set up a formula. 50+25x=375. Step 1: Subtract 50. 25x=325 Step 2: divide 325 by 50. The answer is 13 months.
