We have,
A polynomial with the highest power of 2 is called a quadratic equation.
A quadratic function whose zeroes are -7 and -3.
This means the quadratic function has zeroes.
x = -7
x + 7 = 0 ____(1)
x = -3
x + 3 = 0 _____(2)
Let the quadratic function be f(x) = y.
From (1) and (2) we get,
y = (x + 7)(x + 3)
y = x² + 3x + 7x + 21
y = x² + 10x + 21
Thus,
The quadratic function whose zeroes are -7 and -3 is
y = x² + 10x + 21

Grandma Gertrude gave 13 pieces of jewelry and Grandma Birdie gave y pieces of jewelry to the Carlson sisters to divide evenly among themselves. There are 5 Carlson sisters. Write an expression that represents the number of pieces of jewelry each sister received.
Answer:
(13 + y ) / 5
Step-by-step explanation:
The total number of jewellery pieces givens by the grandmas is 13 + y
If there are 5 sisters and the jewellery pieces would be divided evenly , each sister would get : (13 + y ) / 5
1 and 2 are vertical angles. If m_1 =
(6x + 11) and m2 = (10x - 9), find m1.
Answer:
x=5
Step-by-step explanation:
You have to put them together 6x+11=10x-9 then you can either subtract 6x or 10x. It would be easier to subtract 6x from 10x. 11=4x-9, then you would add 9 to both sides, finally you divide that answer by 4. That would be the answer to x.
M yde = 21x - 5, m cdy = 10x - 3, and m cde =147 find x
Answer:
x = 5
Step-by-step explanation:
Here, we are interested in calculating the value of x.
We can obtain this from the given angle in the question.
Mathematically;
<CDE = <YDE + <CDY
Thus;
147 = 10x-3 + 21x-5
147 = 31x -8
31x = 8 + 147
31x = 155
x = 155/31
x = 5

Answer: A = (-2, 0) B = (-1, 1) x² + y² = 1/2
Step-by-step explanation:
To find where the line and circle intersect, create a system of equations and use the Substitution method to find the coordinates:
EQ1: x - y + 2 = 0 → x = y - 2
EQ2: x² + 2x + y² = 0 → (y - 2)² + 2(y - 2) + y² = 0
→ (y² - 4y + 4) + (2y - 4) + y² = 0
→ 2y² - 2y = 0
→ 2y(y - 1) = 0
→ 2y = 0 y - 1 = 0
y = 0 y = 1
Plug the y-values into EQ1 to solve for x:
x = y - 2 x = y - 2
x = 0 - 2 x = 1 - 2
x = - 2 x = - 1
Coordinates: (-2, 0) & (-1, 1)

Diameter of AB: d² = (x₂ - x₁)² + (y₂ - y₁)²
= [-2 - (-1)]² + [0 - (-1)]²
= (-2 + 1)² + (0 + 1)²
= (-1)² + 1²
= 1 + 1
d² = 2
d = √2
→ r = √2/2
Equation of a circle is: (x - h)² + (y - k)² = r²
Since a center was not provided for the equation with diameter AB, you can choose any value for center (h, k). I choose to let (h, k) = (0, 0) (x - 0)² + (y - 0)² = (√2/2)²
x² + y² = 2/4

Two dices are tossed. What is probability that you will see even numbers on both dices? Answer should be in reduced
fraction format
Answer:
3/6
Step-by-step explanation:
Well 3 is half of 6 and if you were to turn that into a fraction it would either be 3/6 or 1/2.
The probability that you will see even numbers on both dice will be 0.25.
What is probability?Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences. Then the probability is given as,
P = (Favorable event) / (Total event)
Two dice are tossed. Then the total number of events will be
Total events = 6 × 6
Total events = 36
The probability that you will see even numbers on both dice will be
The number of the favorable event will be given as,
Favorable events = 9
Then the probability is given as,
P = 9 / 36
P = 1/4
P = 0.25
The probability that you will see even numbers on both dice will be 0.25.

The sum of interior angles in a triangle are 180 degrees. Angle B and C are congruent. Angle B is
twenty less than angle A. Write and solve a system of equations using substitution.
Answer:
A = 73.33
B = 53.33
C = 53.33
Step-by-step explanation:
Since they are in a triangle, the sum of the three angles = 180
A + B + C = 180 ••••••(i)
Since B and C are congruent, it means that they are equal;
hence B = C ••••••(ii)
We can rewrite equation i as;
A + B + B = 180
A + 2B = 180 ••••••(iii)
Lastly;
B = A -20 •••••(iv)
Substitute iv into iii
A + 2(A -20) = 180
A + 2A -40 = 180
3A = 180 + 40
3A = 220
A = 220/3 = 73.33
But B = C = A -20 = 73.33 -20 = 53.33
2. Darrell applied for a $5,200 loan from his credit union to purchase new office furniture. The simple annual interest rate on the loan is 5%. How much interest will Darrell save if he obtains the loan for 2 years instead of 2 1/2 years?
Answer: $130
Step-by-step explanation:
Simple interest is calculated as:
= PRT/100
where P = principal = $5200
R = Rate = 5%
T = Time = 2 years
S.I = (PRT)/100
= (5200 × 5 × 2)/100
= 52000/100
= $520
Assuming the loan was obtained for 2 1/2 years, the simple Interest will be:
= (5200 × 5 × 2.5)/100
= 65000/100
= $650
This means he'll have saved:
= $650 - $520
= $130

Answer:x is greater than or equal to -7 but less than 9.
Step-by-step explanation:
Find the lowest and higest points on the graph.
Remember the domain is on the x - axis.
The lowest point on the graph is -7, but the dot is filled in so it must be equal to it.
The next step is that the graph is getting larger so it is greater than or equal to.
On the other side of the graph do the same but it is less than not equal because the dot is open.

When a fraction equals zero
5.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
b+36
———— • 12 = 0 • 12
12
Now, on the left hand side, the 12 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
b+36 = 0
Solving a Single Variable Equation:
5.2 Solve : b+36 = 0
Subtract 36 from both sides of the equation :
b = -36

Is it possible to find a value of $x$x so that the value of the surface area (in square inches) is equal to the value of the volume (in cubic inches)? A rectangular prism with length labeled x inches, width labeled 6 inches, and height labeled 3 inches.
Answer:
No, it’s not possible according to calculations
Step-by-step explanation:
Mathematically, the area of a rectangular prism is;
2(wl + wh + lh)
Where w is the width, l is the length and h is the height;
Making the substitutions with values in the question
Surface area = 2(6x + 3x + 3(6))
Surface Area = 2(9x + 18) = 18x + 36 square inches
Volume of rectangular prism = l * w * h
Making substitutions;
V = x * 6 * 3 = 18x cubic inches
So therefore to get the value of x, we equate the surface area to the volume;
18x = 18x + 36
We can see that 18x will cancel out and will render our equation invalid
A die is rolled and a coin is tossed.
Find the probability that an odd number is followed by either a head or a tail?
Answer: The probability of an odd number is 1/2, and the probability of a tail is also 1/2, so the probability of both occurring is the product, 1/4.
Step-by-step explanation: The coin is fair, the probabilities of getting a head and a tail are equal to 12 . The probability of getting an even number on a die is 36=12 because among 6 results there are 3 even numbers
Answer:
There are three outcomes in which tails occur with an even number (2, tails), (4, tails), (6, tails). The probability of this event is 3 / 12 = 1 / 4. The probability that tails and an even number do not occur together is. 1 - 1 / 4 = 3.4
