[tex]\longrightarrow \boxed{\dfrac{ -b}{c}}[/tex]
Step-by-step explanation:
Given that , α and ß are the zeroes of the polynomial ,
[tex]\longrightarrow f(x) = ax^2+bx + c [/tex]
As , we know that ,
Sum of zeroes = -b/a Product of zeroes = c/aWe need to find out the Value of ,
[tex]\longrightarrow \dfrac{1}{\alpha}+\dfrac{1}{\beta} [/tex]
On simplifying ,
[tex]\longrightarrow \dfrac{ \alpha +\beta }{\alpha\beta} [/tex]
Substitute ,
[tex]\longrightarrow \dfrac{\frac{-b}{a}}{\frac{c}{a}}[/tex]
Cancel " a" in numerator and denominator ,

Which is greater or less than 500mL or 50 L
Answer:
50L is larger than 500 ML because 1L=1000ml and. 1ML= 1 ML.
Step-by-step explanation:
Answer: 50 L
Step-by-step explanation:
In order to compare both, let's first transform 500 mL into L. We know that 1 L is 1000 mL. So 500 mL = 0.5 L. We should now look at both numbers. The answer would be 50 L, since 50 is superior to 0.5

PLEASE HELP WILL GIVE BRAINIEST!!! Alex has 25 red, yellow, and orange stress balls. He has twice as many red stress balls as yellow stress balls and three fewer orange stress balls than yellow stress balls. Write and solve an equation to determine how many of each color stress ball alex has.
Answer: O- 9.5 Y- 12.5 R-25
Step-by-step explanation: Divide 25 by 2 and 12 goes into 25 twice for 24, and then you would be left with 60 and 12x5=60 so you get 12.5 for Yellow then you would subtract 3 from 12.5 for 9.5 for Orange. Tell me if theirs anything you dont understand.
A book was sold for $575 there by gaining 15%. find the cost price of the book.
Answer:
$661.25
Step-by-step explanation:
x over 575 times 15 over 100
100=86.25
86.25 is the 15% upcharge
so add 86.25 to the original price
so 575 + 86.25
$661.25

find the common factor !
A bakery sells chocolate, cinnamon, maple, honey, and jelly donuts. It currently has
48 total donuts in stock. If Xiwen picks one donut from the bakery at random, she
has a 1/4 chance of picking a chocolate donut. How many chocolate donuts does
the bakery have in stock?
Since the bakery has only 48 donuts in stock and Xiwen has a 1/4 chance of picking a chocolate donut, there are a dozen (12) chocolate donuts in stock.
1/4 = 0.25
0.25 x 48 = 12

After bisecting an angle, Kira has two New angles, each with q measure of 18°. What was the measure of the original angle?
a) 54 degrees
b)18 degrees
c) 9 degrees
d)36 degrees
Answer:
36 Degrees
Step-by-step explanation:
The definition of an angle bisector is to split the angle into 2 equal parts.
We can then add 18 + 18 degrees to get our original 36 degree angle.

2x²+x-3 is the right answer.In a certain arithmetic sequence, consecutive terms have a positive common difference. The first 4 terms of the sequence have a sum of 80. Which of the following values CANNOT be thefirst term of the arithmetic sequence?
a - 10
b - 12
c - 16
d - 18
e - 20
Answer:
E:20
Step-by-step explanation:
I had the same question and it correct answer was E.
The first term of the arithmetic sequence will be 20. Then the correct option is E.
What is an arithmetic sequence?Arithmetic succession or arithmetic sequential is a numerical series in which the difference between subsequent terms is uniform.
In a specific number juggling grouping, successive terms have a positive normal distinction. The initial 4 terms of the grouping have an amount of 80.
Let the four terms be a - 3d, a - d, a + d, and a + 3d. Then the sum of the four-term is given as,
a - 3d + a - d + a + d + a + 3d = 80
Simplify the equation, then we have
a - 3d + a - d + a + d + a + 3d = 80
4a = 80
a = 80 / 4
a = 20
The first term of the arithmetic sequence will be 20. Then the correct option is E.

What is the solution to the system of linear equations? Show your work using either substitution or elimination.
Problem:
3x-2y=7
y=x+2
please tell me how you got the answer.
Answer:
3x - 2y = 7
Where y = x + 2
3x - 2(x + 2) = 7
3x - 2x - 4 = 7
x = 11
Step-by-step explanation:
If you are solving for X and y = x+2 then you write the equation out like this.
3x - 2(x +2) = 7 …. You substitute the x + 2 for y and then solve for x.
2x - 2 times x + 2 times - 2 = 7. That becomes 3x - 2x - 4 = 7. You then subtract 2x from 3x to give you X. Then you add 4 on one side to zero it out and add 4 to the other side. 7 + 4 = 11. This gives you the answer X = 11.
Assume y=5x and dx/dt = 2 find dy/dt
Answer: 10
Step-by-step explanation: since dx/dt = 2, you have to create an equation. dx/dt = dy/dt * dx/dy is your equation. now we substitute. 2 = dy/dt *dx/dy. find the derivative of 5x in terms of y (dx/dy), which is 1/5. so now your equation is 2 = dy/dt * 1/5. solve for dy/dt and your answer is 10.

The scale is 1 inch = 15 feet. Multiply the inches of the drawing by 15to get total feet:
1 2/3 x 15 = 25 feet
2 x 15 = 30 feet
The court is 25 ft by 30 feet
This is smaller than 25 by 75 so it will fit
