Answer:
Well, we can write a really simple quadratic polynomial as:
P(x) = a*(x - c1)*(x - c2)
Where a is a constat, and c1 and c2 are the roots, here we have:
c1 = 5 and c2 = -3
P(x) = a*(x -5)(x + 3) = a*x^2 + a*x*3 - a*5*x - a*15
then the quadratic polynomial can be:
P(x) = a*x^2 + a*(3 - 5)*x - a*15
P(x) = a*x^2 - 2*a*x - a*15
Where a can be any real number.

find y of a paralagram
Answers
Answer:
y = 15
Step-by-step explanation:
In a parallelogram, opposite sides are congruent.
5y - 20 = 2y + 25
3y = 45
y = 15
Answer:
y = 15
Step-by-step explanation:
The top and bottom sides have to be equal in length
5y-20 = 2y+25
Subtract 2y from each side
5y-2y-20 = 2y-2y+25
3y -20 = 25
Add 20 to each side
3y = 20+25
3y = 45
Divide each side by 3
3y/3 = 45/3
y = 15

Tuition for one year at the University of Atlantis costs $12,000 per year. Rachel would like to attend this university and will save money each month for the next 3 years. Her parents will contribute $3,000 for her first year's tuition. How much money will Rachel need to save each month to have enough money for the first year of college at the University of Atlantis?
Answers
Answer:
250 dollars per month.
Step-by-step explanation:
We first need to subtract the amount of money her parents are giving her.
12000-3000=9000.
Since she is saving money every month for 3 years we have to multiply 3×12=36 months.
We than need to divide how much money she needs by the amount of months she has to get it.
9000÷36=250
Complete the square to solve 4x2 + 24x = 4.
Answers
Answer:
x = - 3 ± [tex]\sqrt{10}[/tex]
Step-by-step explanation:
Given
4x² + 24x = 4 ( divide through by 4 )
x² + 6x = 1
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(3)x + 9 = 1 + 9
(x + 3)² = 10 ( take the square root of both sides )
x + 3 = ± [tex]\sqrt{10}[/tex] ( subtract 3 from both sides )
x = - 3 ± [tex]\sqrt{10}[/tex]
Answer:
X=1/8
Step-by-step explanation:
Calculate the product 4x×2 + 24x = 4
Collect like terms 8x + 24x = 4
Divide both sides of the equation by "32" 32x = 4
Solution x = 1/8

Answer:
m∠M = 116° m∠N = 111° m∠O = 64° m∠P = 69°Step-by-step explanation:
A quadrilateral can be inscribed in a circle only if the sum of its opposite angles is equal to 180°, so:
7x - 15 + 3x + 15 = 180° and 2(17y - 10) + 13y + 12 = 180°
10x = 180° 34y - 20 + 13y + 12 = 180°
x = 18° 47y = 188°
y = 4°
m∠M: 2(17•4 - 10) = 2•58° = 116
m∠N: 7•18 - 15 =126 - 15 = 111
m∠O: 13•4 + 12 = 52 + 12 = 64
m∠P: 3•18 + 15 = 54 + 15 = 69

Answers
4n-6 (n-2) = -24 + 7n
You first multiply the six with the equation in the parentheses making it:
4n-6n + 12= -24 + 7n
You then subtract 4n from -6n changing it to:
-2n + 12 = -24 + 7n after that you switch the 12 and 7n so that the equation can be
-2n -7n = -24 - 12
After that combine the numbers together:
-9n = -36
Then divide both sides by -9 making
n= 4
Two angles form a
linear pair. The
measure of one
angle is three times
the measure of the
other. Find the
measure of each
Answers
Answer:
45° and 135°
Step-by-step explanation:
A linear pair of angles sum to 180°
let one angle be x , then the other is 3x ( 3 times the other ), thus
x + 3x = 180
4x = 180 ( divide both sides by 4 )
x = 45
Thus the 2 angles are
x = 45° and 3x = 3 × 45° = 135°
The measure of two angles are 135 and 45 degrees if the two angles form a linear pair. The measure of one angle is three times the measure of the other.
What is an angle?When two lines or rays converge at the same point, the measurement between them is called a "Angle."
It is given that:
Two angles form a linear pair. The measure of one angle is three times the measure of the other.
As we know,
If two angles form a linear pair it means the angle made by the pair is 180 degrees
Let the two angles are x and y
x + y = 180
x = 3y (one angle is three times the measure of the other)
Solving the two linear equations in two variable:
3y + y = 180
4y = 180
y = 180/4
y = 45 degrees
x = 3(45) = 135 degrees
Thus, the measure of two angles are 135 and 45 degrees if the two angles form a linear pair. The measure of one angle is three times the measure of the other.

The sum of the digits of a two digit number is 10 when the dishes are reversed the number increases by 18 find the original number
Answers
Answer:
Step-by-step explanation:
Hello, we can write this number ab where a and b are integer betwen 0 and 9.
For instance, 54, a = 5, b = 4
And then, we can say ab = 10 * a + b.
For instance, 54 = 50 + 4 = 5*10 + 4.
The sum of the digits of a two digit number is 10.
a + b = 10
When the dishes are reversed the number increases by 18.
10b + a = 18 + 10a + b
9b = 18 + 9a
b = 2 + a
We replace in the first equation to get.
a + 2 + a = 10
2a = 10 -2 = 8
a = 4
and then, b = 6
So, the number is 46.

( a ) Well we know that the limit for the range is 400 dollars, as ( 1 ) her greatest balance was 400 dollars, and ( 2 ) the balance is dependent on the days, and hence represents the range. Respectively the limit for the domain would be 3 weeks.
( b ) Remember that B(0) models the balance over the course of 0 days. As you can see that starting mark is about half of the greatest balance on the graph, 400 dollars. Therefore you can estimate B(0) to be $200.
( c ) B(12) models the balance over the course of 12 days. It mentions that at B(12) the balance reaches $0, so in function notation that would be :
B(12) = 0
( d ) Segment 4 would represent that information. As you can see on the graph, the only time period with which the balance became 0 is represented by the fourth segment.

Answers
Answer: d) v = 3.20 + 1.50n.
Step-by-step explanation:
Let 'v' be the price to pay in a 'n' kilometer.
Given: The price to be paid for a taxi ride includes a fixed parcel, called a flag, and a parcel that depends on the distance traveled.
Flag costs = $ 3.20 and
Each kilometre run costs = $ 1.50
Then, the amount of 'v' to pay in a 'n' kilometer race = Flag costs + (n)× (Each kilometre run costs )
⇒ v= 3.20 + 1.50n
Hence, the correct option is d) v = 3.20 + 1.50n.

Plug in the values from the set {12, 15, 18, 19} to find the value of x. The value that holds true for the equation is . So, Jenny is years old and her mother is years old.
Answers
Answer:
Jenny´s age is 19 and her mother is 43.
Step-by-step explanation:
Given that
x + 2x + 5 = 62
where,
x = Jenny’s age
Now the following cases occured
a.
x = 12
Now put the x value to the above equation
12 + 2(12) + 5 = 62
12 + 24 + 5 = 62
41 = 62
It is not equaled so the Jenny age is not 12
b.
x = 15
Now put the x value to the above equation
12 + 2(15) + 5 = 62
15 + 30 + 5 = 62
50 = 62
It is not equaled so the Jenny age is not 15
c.
x = 18
Now put the x value to the above equation
18 + 2(18) + 5 = 62
18 + 36 + 5 = 62
59 = 62
It is not equaled so the Jenny age is not 12
d.
x = 19
Now put the x value to the above equation
19 + 2(19) + 5 = 62
19 + 38 + 5 = 62
62 = 62
It is equaled so the Jenny age is 19
Now the mother age is
as we know that
x + y = 62
19 + y = 62
y = 62 - 19
= 43
Also it proved that if we doubles the jenny age i.e 38 and then add 5 so the total is 43 i.e. equivalent to her mother age
