Answer:
The values of b are [tex]\mathbf{b=\pm18}[/tex]
Step-by-step explanation:
We need to find the value of b will cause [tex]27x^2+ bx +3 = 0[/tex] to have one real solution.
If it has one real solution, the discriminant is zero.
The formula of discriminant is: [tex]b^2-4ac[/tex]
In our case: [tex]b^2-4ac=0[/tex]
We have a=27, b=b and c=3
Putting values to find b
[tex]b^2-4ac=0\\b^2-4(27)(3)=0\\b^2-324=0\\b^2=324\\Taking \ square root \ on \ both \ sides\\\sqrt{b^2}=\sqrt{324}\\b=\pm18[/tex]
So, the values of b are [tex]\mathbf{b=\pm18}[/tex]

8(-8x – 6) = -6x - 22
solve for x
Answer:
x = - 13/29 OR x = - -0.44827586
Step-by-step explanation:
We use PEMDAS to evaluate the equation.
P stands for parenthesis. In this case we distribute the 8 to the equation in parenthesis.
8(-8x - 6)
-64x - 48 = -6x - 22 we will move the terms to their proportional sides
-64x + 6x = 22 + 48 (remember we do the opposite equation to move to the other side of the equals to sign)
-58x = 70 we divide both sides by -58 to isolate x
x = - 13/29 OR x = - -0.44827586

Step-by-step explanation:
(dy/dx) - 2xy = x, y(0) = 0, find y(1).
Answer :
2y=1+e−x2
Solution :
IF=e∫2xdx=ex2
∴y×ex2=∫xex2dx=12∫etdt+C, where x2=t
=12ex2+C.
∴y=12+Cex2
Putting y=1andx=0, we get C=12.
julie opens a bank account with $500.she deposits $60 each month.write a function that represents the amount that is in julies account after x months
Answer:
[tex]f(x) = 500 + 60x[/tex]
Step-by-step explanation:
Given
[tex]Ope\ ning\ Balance = 500[/tex]
[tex]Deposits = 60[/tex] --- monthly
Required
Write as a function
Represent the number of months with x and the balance at any month with f(x)
f(x) is calculated as thus:
Opening Balance + Deposits * Number of Months
So, we have:
[tex]f(x) = 500 + 60 * x[/tex]
[tex]f(x) = 500 + 60x[/tex]
Hence, the function that represents the scenario is
[tex]f(x) = 500 + 60x[/tex]

American Airlines charges $270 for a flight to Denver and $50 for each piece of luggage. Delta Airlines charges $330 for a flight and only $30 for each piece of luggage. Which inequality shows the number of pieces of luggage that need to be checked for American Airlines to cost more than Delta Airines for a flight to Denver?
F 270 + 50x > 330 + 30x
G 270x +50 > 330x + 30
H 270x + 50 < 330x +30
J 270 +50x > 330 + 30x
Answer:
J; 250 + 50x > 330 + 30x
Step-by-step explanation:
Since we don't have to worry about formatting the numbers to slope-intercept form, we can start the process of elimination.
First, we can disregard G and H because both have the x in the wrong place:
—> F 270 + 50x ≥ 330 + 30x
—> G 270x + 50 > 330x + 30
—> H 270x + 50 < 330x +30
—> J 270 + 50x > 330 + 30x
We're looking for 270 + 50x > 330 + 30x.
Next, we determine which symbols are correct. Since the question is only asking for when American Airlines would be more expensive, not when it would be just as much or more, we can get rid of F.
—> F 270 + 50x ≥ 330 + 30x
—> J 270 +50x > 330 + 30x
We finally have our answer, J.

An equilateral triangle has sides of equal length. Find the dimensions of an equilateral triangle with a perimeter of 45 inches. P=4s
Answer:
P= 4s
P= 4(45)
P= 180 in.
Explanation: write down the formula first. Then write down P= 4s, but change the "s" to the 45. Then multiply 45 by 4 then you have your answer. If your teacher ask you for an degrees it will be 180°. Which is also the sum of a triangle.

Answer:
y = -x +1
Step-by-step explanation:
-0+1 = 1
-(-6)+1 = 7
etc
Answer:
y = - x + 1
Step-by-step explanation:
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
y - [tex]y_{1}[/tex] = m( x - [tex]x_{2}[/tex] ) point - slope form
y = mx + b slope - intercept form
~~~~~~~~~~~~
(1, 0)
(3, - 2)
m = ( - 2 - 0 ) / ( 3 - 1 ) = - 1
y - 0 = ( - 1)(x - 1)
y = - x + 1

27x+2=26x+6
-26x -26x
x+2=6
-2 -2
x=4
Answer:
x = 4
Step-by-step explanation:
Vertically opposite angles are equal
27x + 2 = 26x + 6 {Subtract 26x from both sides}
27x -26x + 2 = 6
x + 2 = 6 {Subtract 2 form both sides}
x = 6 - 2
x = 4

No one likes a dried out turkey! The moisture content, m, of the turkey after it cooks for t hours is given by: m
=-0.0082 -0.09+1. The ideal juiciness of a turkey is a 20% (ie 0.20) moisture content. How many hours
does the turkey cook to reach that 20% moisture content? If the bird needs to cook for at least 6 hours to reach a
safe internal temperature, is it possible to still have at least 20% moisture content?
