write a quadratic function in standard form with zeros 9 and -3 PLZZZZZ HELPP MEEE
Answer:
f(x)=x^2-6x-27
Step-by-step explanation:
x=9 and x-3
set the equal to zero: x-9=0 and x+3=0
x-9 and x+3 are now the factors of your equation:
you equation so far is: (x-9)(x+3)=0
next factor these together to get: f(x)=x^2+3x-9x-27
finally simplify the equation leaving you with f(x)=x^2-6x-27
Felipe es encargado de un laboratorio de informática y sabe que los alumnos frecuentemente ocupan memorias USB, con el fin de apoyar a los alumnos compra 100 memorias que a precio de mayoreo le salen a $92 cada una. Felipe vende cada USB en $100 ¿cual es el porcentaje de ganancia que obtiene Felipe por la venta de cada memoria?
Explicación paso a paso:
Cantidad total de USB comprado = 100
Precio al por mayor = $ 92
Costo de 100 memorias USB = 100 * $ 92 = $ 9,200
Si vende cada memoria USB por $ 100 cada una a precio minorista, la cantidad total en 100 USB será;
100 * $ 100 = $ 10,000
% beneficio = beneficio / precio de coste * 100%
Beneficio = precio de venta - precio de costo
Beneficio = $ 10,000 - $ 9,200
Beneficio = $ 800
% de beneficio = 800/9200 * 100
% de beneficio = 800/92
% beneficio = 8,696%
De ahí que el porcentaje de beneficio que obtiene felipe por cada venta de cada recuerdo es del 8,696%

If you buy a car for $5,000 and you put down $1,500 for a down payment, how much equity will you have in the car?
A. $1,500
B. $5,000
C. $6,500
D. $3,500
Answer:
C.$6,500
Step-by-step explanation:
Because you payed $5,000 for a car and $1,500 more for a down payment, so we would have to add.
$5,000 (cost of car) + $1,500 (cost of down payment) = $6,500 (total pay)

A triangle has angles of 124°, 28° and 28°.
Using the given angle measures, how many triangles can be formed (one unique, more than one, or none)? Explain your answer.
Answer:
1 unique
Step-by-step explanation:
Given the angles of the triangle in the question, only one unique triangle can be formed.
This is because, if we look at the angles given, we can see that we have two of the angles equal.
This will give rise to the formation of an isosceles triangle which is a triangle in which two of the sides are equal in length
The equal angles made it in such a way that this is the only type of triangle that can be formed from the angles given
What is the measurement for the exterior angle
First we find [tex]\angle ACB[/tex]
[tex]\angle ACB = 180 - (4x - 100) = 180 - 4x + 100 = 280 - 4x[/tex]
Then we find a equation for all the interior angles
[tex]180 = \angle ACB + \angle BAC + \angle ABC\\= 280 - 4x + x + 20 + x\\300 - 2x[/tex]
We solve for x
[tex]180 = 300 - 2x\\180 - 300 = -2x\\-120 = -2x\\2x = 120\\x = 60\\[/tex]
Now we find the exterior angle
[tex]\angle DCB = 4x - 100 = 4 \cdot 60 - 100 = 240 - 100 = 140[/tex]
Which theorem would be used to write 4x+4=92 in the diagram below?
Answer: C) Alternate interior angles
The blue angles marked are inside the parallel lines, so they are considered interior. They are on alternating sides of the transversal line. The angles are only congruent when the lines are parallel.
Answer: C

Write and solve an equation for this situation. In one baseball season, Peter hit twice the difference between the number of home runs Alice hit and 3. Altogether, they hit 9 home runs. How many home runs did each player hit that season? Let h represent Alice's home runs. Alice hit home runs. Peter hit home runs.
Answer:
Y=8
Step-by-step explanation:
The difference between the number Alice hit and 6 is X - 6. Twice that would be 2(X-6). So Y = 2(X-6). We also know that X + Y = 18 so we have 2 equations:
Y = 2(X-6)
X+Y = 18
Let's take the second equation and solve for Y in terms of X
Y = 18 - X
Now take that result and substitute that back into the first equation that starts with Y, because now you know that Y is also equal to 18 - X, now you have:
18 - X = 2(X - 6)
Let's solve for X
18 - X = 2X - 12
18 - 3X = - 12
- 3X = - 30
X = 10 <--number of home runs Alice Hit
That leaves us with Y = 8 <---number of home runs Peter hit
Go back to the original question and make sure the answer fits. The difference between 10 and 6 is 4 and twice that is 8, the number Peter hit. 10 + 8 = 18. Good to go!

Coats are highly seasonal items. Their highest selling month is 450% of their lowest selling month. During the lowest selling month, they sell 360 units. How many units do they sell during the peak month?
a) 820
b) 1,420
c) 1,620
d) 2,820
Answer:
1620
Step-by-step explanation:
450*360/100. xd xd xd
The number of units they sold during the peak month is 1620 units.
Given that, the highest selling month of coats is 450% of their lowest selling month. During the lowest selling month, they sell 360 units.
We need to find out how many units do they sell during the peak month.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the highest number of coats sold in the peak month be x.
So, x= 450% of 360
⇒x=4.5 × 360
⇒x=1,620
Therefore, the number of units they sold during the peak month is 1620 units.

What is an equation of the line that passes through the point (−5,−1) and is parallel to the line 4x+5y=45?
Answer:
y = -4/5x - 5
Step-by-step explanation:
4x + 5y = 45
we need to write it in slope intercept form, so:
5y = -4x + 45
y = -4/5x + 45/5
y = -4/5x + 9
The line is parallel so the slope will be -4/5x, point ( -5 -1 )
y = mx + b
-1 = -4/5(-5)+b
-1 = 4 + b
-1 - 4 = b
-5 = b
y = -4/5x - 5
When Ava went to bed, the temperature was 3°F. When she woke up, the temperature had decreased by 6°F. What was the temperature when Ava woke up?
Answer:
[tex]T_f=9^{\circ} F[/tex]
Step-by-step explanation:
It is given that,
Initial temperature, [tex]T_i=3^{\circ} F[/tex]
The decrease in temperature when she woke up is, [tex]\Delta T=6^{\circ} F[/tex]
We need to find the temperature when Ava woke up.
Change in temperature = final temperature-initial temperature
[tex]6\ ^{\circ}F=T_f-3^{\circ}F\\\\T_f=9^{\circ} F[/tex]
So, when she woke up the temperature was 9°F.
The temperature when Ava woke up is -3°F
What is Integers?Integers come in three types:
Zero (0)Positive Integers (Natural numbers)Negative Integers (Additive inverse of Natural Numbers)Given:
When Ava went to bed, the temperature was 3°F.
and, When she woke up, the temperature had decreased by 6°F.
So, the temperature when Ava woke up
= 3 - 6
= -3°F
Hence, the temperature when Ava woke up is -3°F
