Since 1/2 slope is perpendicular to the equation the slope is -2 which is the opposite of the reciprocal of 1/2.
Since the slope is -2, every time you go forward you go down 2.
(-1, 0)
(0, -2)
The y-intercept is -2.
y = mx + b
y = -2x - 2
The answer is B

4. A room measures 10 meters by 15 meters. How many 30 centimeters by 30 centimeters squares of carpet are needed
to cover the floor of this room?
Answers
Answer:
1667 carpets.
Step-by-step explanation:
For this problem we have to find the
area of room,
area of 1 carpet.
Then we have to find how many such carpet's sum will be equal to area of room.
_______________________________________________
area for rectangle is given by = length * width
area of room = 10 m * 15 m = 150 m. sq.
dimension of carpet = 30 cm * 30 cm
lets converts first 30 cm in meter so that dimension of room and carpet are in same unit that is in meters
100 cm = 1 meter
30 cm = 1/100 * 30 meters = 0.3 meters
area of 1 carpet = 0.3 m * 0.3 m = 0.09 m. sq.
let there be need of x carpet to cover the floor of room.
area of x carpet = area of 1 carpet *x
area of x carpet =0.09x m. sq.
area of x carpet = area of room
0.09x m. sq. = 150 m. sq.
x = 150/0.09 = 1666.67
Thus, there will be need of 1666.67 carpets but carpets cannot be in fraction
hence rounding the number of carpet to nearest whole number.
there will be need of 1667 carpets.

Answer:
1) y=1/5x +0.8
2) y= -2x +10
Step-by-step explanation:
It's been a while, but I think this is right:
1)
For 2 lines to be parallel they must have the same slope
Recall that the equation of a line is
y-y1 = m (x- x1)
m being slope
So looking at equation 1, we can tell that the slope is 1/5 because it has already been distributed to the x.
So we know our equation will look something like this
y-y1 = 1/5 (x- x1)
We also know that the line passes through the point (8,1)
So, you plug in those points to your equation
y- 1 = 1/5(x - 8)
Simplifying and distributing the equation, we end up with
y= 1/5x + 0.8
(if you would like me to explain the simplification plz ask in a comment.)
2)
First you have to move -x from the left side of the equation to the right, making the equation
2y= x+10
then divide by 2 on both sides (im writing x/2 as 1/2x, because they are the same)
y= 1/2x + 5
For 2 lines to be perpendicular they must have the opposite reciprocal slope
Meaning if you had a slope of 2, the opposite would be -2 and the reciprocal would be 1/2, so your slope would be -1/2
Knowing this and keeping in mind our equation of a line from the first question, our slope of a perpendicular line (or m in our equation) of y= 1/2x + 5
would be -2
So far we have an equation that looks like
y-y1 = -2 (x- x1)
So now we plug in our points (6, -2)
(y- -2)
y + 2 = -2 (x - 6)
Simplifying and distributing the equation, we end up with
y= -2x +10
(if you would like me to explain the simplification or have a question don't hesitate to ask in a comment.)
Answer: 1.) y = 1/5 x - 3/5
2.) y = -2x + 10
Step-by-step explanation:
1.) Keep the same slope. Substitute the y and x-values from the given coordinate into the slope-intercept form and solve for the new b
1 = 1/5(8) + b 1 = 8/5 +b .subtract 8/5 form both sides:
-3/5 = b
y = 1/5 x - 3/5
2.) Rewrite the given equation in slope-intercept form
-x + 2y = 10 becomes y= 1/2 x +10
Take the reciprocal of the slope and reverse the sign: 1/2 becomes -2
Substitute the y and x-values from the given coordinate into the slope-intercept equation and solve for b.
-2 = -2(6) + b
-2 = -12 + b Add +12 to both sides
10 = b
y = -2x + 10 Standard form: 2x + y = 10

What is the future value of the loan in the previous problem if the interest is compounded
monthly (all other conditions remain the same)?
Answers
Answer:Your calculator should now display a screen with these variables. I have written what each
variable stands for next to the variable. You calculator likely has numbers next to some of the
variables. This is okay. We will type over them when we need to solve a specific loan problem.
N Number of payments
I% Annual interest rate
PV Loan amount (Normally
entered as a POSITIVE
number in loan problems.)
PMT Monthly payment amount
(Usually entered as a
NEGATIVE number in loan
problems.)
FV Balance when loan is paid
off. (Usually 0 in a loan
problem.)
P/Y Number of payments per
year. (Usually 12 in a loan
problem.)
C/Y How often interest is
charged. (Usually 12 in a
loan problem)
Begin / End Choose Begin if you make a
loan payment the day you
take your loan. Otherwise
choose End. We will always
leave this on END.
Example: A new car is purchased and a $25,000 loan is taken. The loan is for 6 years (72
months) and the interest rate is 4.9% compounded monthly. What is the monthly payment?
Calculator steps: Hit APPS button then select Finance then select TVM solver.
We will solve most of the problems in this chapter from this screen. We need to know what
each variable represents. We will enter values for every variable except for the one we are
solving for. We are computing a monthly payment. We will put values in for every variable,
except (PMT). PMT stands for the payment.
Enter these values on your calculator.
N (number of payments) 72
I% (annual interest rate) 4.9
PV (Loan amount, make
this amount positive.)
25000
PMT Move cursor here and hit
green alpha button then
enter after you have entered
every other value.
FV (what you owe after
make all payments)
0
P/Y (payments per year) 12
C/Y (how often interest is
paid)
12
Begin / End
(We will always leave this
on end.)
End
Once you have entered all of the amounts scroll up to PMT. Make sure your cursor is flashing
next to PMT. It doesn’t matter what value is in the PMT. Your calculator will put in the correct
payment when you tell it to compute the payment. Hit the green ALPHA button the ENTER.
