Find the missing endpoint endpoint h (-1,0) midpoint p(0,-1)​

Mathematics
1 answer:
CaHeK987 [17]3 years ago
6 0

Answer:

Step-by-step explanation:

Let the other end point be (a,b)

Then the midpoint p(0,-1) is between the two end points (-1,0) and (a,b)

So

(0,-1) = ( (-1+a)/2 , (0+b)/2)

So we have

0 = (-1 +a) /2

0 = -1 + a

a =1

and

-1 = (0+b)/2

-2 = 0+b

b = -2

So the other end point is ( 1, -2)

Limit question thing plz help me
Sphinxa [80]

Answer:

The limit does not exist

Step-by-step explanation

For this question you have to look at the function and see what y value does it approach as it gets closer and closer to x =2, from the left side it looks like it approaces 4 and from the left side it looks like it's approaching 1, since the limits from the left and right sides are not the same, the limit does not exist

Tim installs 50 square feet of his floor in 45 minutes. At this rate how long does it take him to install 495 square feet.
Nina [5.8K]
50 sqft = 45 min
495 sqft = x min

495/50 is 9.9. So we know we multiplied 50 by 9.9 to change it to 495.
Do the same on the other side. 45 x 9.9 = 445.5.

It will take him 445.5 minutes, or 7.425 hours

List benefits of having a checking account
VikaD [51]

Checking Account Advantages

Checking account holders have access to online and mobile banking, ATMs and the use of debit cards and checks to make purchases or withdraw funds from the account. Many employees find checking accounts useful for direct deposit of their paychecks. With direct deposit, an employer automatically transfers a payroll amount into the employees banking account, saving time and avoiding trips to the bank to cash paychecks. Most checking accounts in the United Stated are also insured by the Federal Deposit Insurance Corporation, or FDIC, for up to $250,000, which ensures an account holder that his money is safely stored at the bank.


couldn't really find a list besides knowing its a easier way to give money when you dont have any on you.

Which equation models a line that is perpendicular to y = x - 1 and goes through the point (5,4)
PtichkaEL [24]

Answer:

y = - x + 9

Step-by-step explanation:

Because the line is perpendicular, the slope with be the opposite reciprocal. So, if the slope is 1 as in the equation y = x - 1, the opposite reciprocal is -1.

So the equation that is perpendicular will look like this so far:

y = -x + b   (b represents our y-intercept that we have not found yet)

Now we will find the y-intercept. We can find it by substituting the coordinates (5,4) as x and y into the equation right above ^^.

So,  4 = -(5) +b     or     4 = -5 + b

Add 5 to both sides to isolate b on the right side. b = 9

Therefore, the y-intercept is 9.

Now we have found everything we need for the equation, which is

y = - x + 9
