Answer:
11
Step-by-step explanation:
A is -7 and b is -4 if you add them it would be positive 11 because a negative plus a negative is a positive. Here's this to keep in mind:
+(+) Two like signs become a positive sign 3+(+2) = 3 + 2 = 5
−(−) 6−(−3) = 6 + 3 = 9
+(−) Two unlike signs become a negative sign 7+(−2) = 7 − 2 = 5
−(+) 8−(+2) = 8 − 2 = 6
if a polynomial is divided by x-5, the quotient is 2x^2 +8x-9 and the remainder is 3 what is the original polynomial?
Answer:
[tex]P(x)=2x^3-2x^2-49x+48[/tex]
Step-by-step explanation:
Let the original polynomial be [tex]P(x)[/tex].
We know that when it is divided by [tex](x-5)[/tex], the quotient is [tex]2x^2+8x-9[/tex] and we get a remainder of 3.
Therefore, this means that:
[tex]\frac{P(x)}{x-5}=2x^2+8x-9+\frac{3}{x-5}[/tex]
Remember what it means when we have a remainder. Say we have 13 divided by 3. Our quotient will be 4 R1, or 4 1 over 3. We put the remainder over the divisor. This is the same thing for polynomials.
So, to find our original polynomial, multiply both sides by [tex](x-5)[/tex]:
[tex](x-5)\frac{P(x)}{x-5}=(x-5)(2x^2+8x-9+\frac{3}{x-5})[/tex]
The left side will cancel. Distribute the right:
[tex]P(x)=2x^2(x-5)+8x(x-5)-9(x-5)+\frac{3}{(x-5)}(x-5)[/tex]
Distribute:
[tex]P(x)=(2x^3-10x^2)+(8x^2-40x)+(-9x+45)+(3)[/tex]
Combine like terms:
[tex]P(x)=(2x^3)+(-10x^2+8x^2)+(-40x-9x)+(45+3)[/tex]
Evaluate:
[tex]P(x)=2x^3-2x^2-49x+48[/tex]
And we're done!

Ruben bought 666 comic books for \$21$21dollar sign, 21. Each comic book was the same price.
what was the cost for 1 comic book
9514 1404 393
Answer:
$3.50
Step-by-step explanation:
If c represents the cost of one comic book, the transaction can be written as the equation ...
6c = $21
Dividing by 6, we get ...
c = $21/6 = $3.50
The cost for 1 comic book was $3.50.
_____
You know that the total cost of a transaction is the sum of the costs of each part. When all the parts have the same value, we can multiply the cost of one part by the number of parts.
Answer:
3.50

The area of the circle is 144π m2
What is the diameter of the circle?
Answer:
Step-by-step explanation:
Remember that
Area of Circle = [tex]\pi r^2[/tex]
[tex]\pi = pi \\r = radius[/tex]
They told us that for this circle, the area is [tex]144\pi m^2[/tex]
If you put it back into the formula for area of a circle we get:
Area of Circle = [tex]\pi r^2[/tex]
[tex]144\pi = \pi r^2[/tex]
Divide both sides by [tex]\pi[/tex].
144 = [tex]r^2[/tex]
Now we want to solve for r (r = radius).
You need to square root each side
[tex]\sqrt{144} = \sqrt{r^2}[/tex]
[tex]12 = r[/tex]
So now we know the radius, [tex]r = 12[/tex] metres
Also remember that
Diameter = [tex]2r[/tex]
So,
Diameter = 2 times 12 = 24 metres
The required diameter of the given circle is 24 meters.
What is an area circle?The area of the circle is given by the pie times square of the radius.
Area of circle = πr^2
Here,
The given area of the circle is 144π m²
And we know that,
Area = πr²
substitute the value of the area in the above expression,
144π = πr²
r² = 144
r = √144
r = 12 meters
Since,
Diameter = 2 × radius
Diameter = 2 × 12 = 24 meter
Thus, the required diameter of the given circle is 24 meters.

what is the simplification for this ? 2y+3=4y+2
Answer:
2y-1
Step-by-step explanation:
Answer: y = 1/2 in decimal form = 0.500
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
2*y+3-(4*y+2)=0
olve : -2y+1 = 0
Subtract 1 from both sides of the equation :
-2y = -1
Multiply both sides of the equation by (-1) : 2y = 1
Divide both sides of the equation by 2:
y = 1/2 = 0.500

. During a volleyball training session, Idalie drank twice as much water as Adamaris, and Jonathan
Arank 100 mL more water than Idalie. Between them they drank 3 liters of water. How much water
did Adamaris drink?
Answer:
Step-by-step explanation:
Let's say I = amount of water Idalie drank,
A = amount of water Adamaris drank
J = amount of water Jonathan drank.
We are told Idalie drank twice as much water as Adamaris. You can write it as:
Idalie = 2 times Adamaris
I = 2A
Then we are told Jonathan drank 100ml more than Idalie. So
Jonathan = 100 + Idalie
J = 100 + I (and we know I = 2A)
J = 100 + 2A
Between them they drank 3 liters (3L = 3000ml) of water.
Idalie + Adalie + Jonathan = 3000
I + A + J = 300
So since we know I = 2A and J = 100 + 2A, we can put it into the equation above:
2A + A + 100 + 2A = 3000
Gather the like terms and you get:
5A + 100 = 3000
Subtract 100 from both sides.
5A = 3000 - 100 = 2900
To find A, divide both sides by 5
A = 2900/5 = 580
This means Adamaris drank 580ml of water

You need a loan of $110 comma 000 to buy a home. Calculate your monthly payments and total closing costs for each choice below. Briefly discuss how you would decide between the two choices. Choice 1: 15-year fixed rate at 6% with closing costs of $1200 and no points. Choice 2: 15-year fixed rate at 5.5% with closing costs of $1200 and 4 points.
What is the monthly payment for choice 1? $
(Do not round until the final answer. Then round to the nearest cent as needed.)
Answer:
Monthly payment for choice 1 is $6,600
Step-by-step explanation:
We will use following formula in order to calculate the monthly payment of choice 1
Value of Loan = Monthly payment x ( 1 - ( 1 + Interest rate )^-numbers of payments / interest rate
Where
Value of Loan = $110,000
Interest rate = 6%
Numbers of Payment = 15 years x 12 payments / year = 180 payments
Placing values in the formula
$110,000 = Monthly payment x ( 1 - ( 1 + 6% )^-180 ) / 6%
$110,000 = Monthly payment x 16.6662
Monthly Payment = $110,000 / 16.6662
Monthly Payment = $6,600.18
Monthly Payment = $6,600 (Rounded to whole number)

Jerome hiked three-fourths of a mile in two-thirds of an hour. What was his hiking speed in miles per hour?
The value of his hiking speed in miles per hour will be;
⇒ Speed = 9/16 miles per hour
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Jerome hiked 3/4 of a mile in 2/3 of an hour.
Now,
Since, Jerome hiked 3/4 of a mile in 2/3 of an hour.
Hence, We can formulate;
⇒ Speed = Distance / Time
⇒ Speed = 3/4 / 2/3
⇒ Speed = 3×3 / 4×4
⇒ Speed = 9/16 miles per hour
Thus, The value of his hiking speed in miles per hour will be;
⇒ Speed = 9/16 miles per hour

Cars are made in a factory for 24 hours every day.
In the factory a car is made every 209 seconds.
Work out an estimate for the number of cars made in the factory in one year.
Answer:
6,591,024,000
Step-by-step explanation:
Minutes in 24 hours=1,440
number of seconds in 24 hours=60*1440
=86,400..
number of cars made in each second=209
number of cars made in 86,400 seconds= 18,057,600
24 hours =one day
1 year =365 days
cars made in one year =365*18,057,600
=6,591,024,000
therefore, the number of cars made in one year =
6,591,024,000
The number of cars made in the factory in one year where cars are made for 24 hours every day is 150891.
What is the relation between work and time?The total time taken is inversely proportional to the rate of work. If a unit of work is done in total n number of days, then the total work done W in a day can is,
[tex]W=\dfrac{1}{n}[/tex]
In a factory, cars are made, where Cars are made for 24 hours every day. As, there is total 60 seconds in one minute and 60 minutes in one hour. Thus, the number of second in 24 hours is,
[tex]24\times60\times60=86400[/tex]
In the factory, a car is made every 209 seconds. Thus, the number of cars made in 86400 seconds (24 hours),
[tex]\dfrac{86400}{209}=431.4[/tex]
There is total 365 days (24 hours) in one year. Thus, the number of cars made in the factory in one year is,
[tex]431.4\times365=150891[/tex]
Thus, the number of cars made in the factory in one year where cars are made for 24 hours every day is 150891.

We get rid of parentheses
-11x+13+20=0
We add all the numbers together, and all the variables
-11x+33=0
We move all terms containing x to the left, all other terms to the right
