Consider this quadratic equation:
2x2+1x+3=0
Comparing it to the standard form, name a, b, and c
a=
b=
C=

Answers

Answer 1

Explanation: The value for a comes from the coefficient

on the x² term which in this case is 2 so we say that a = 2.

The value for b comes from the coefficient on the x term

which in this case is 1 so we say that b = 1.

The value for c comes from the constant term

which in this case is 3 so we say that c = 3.

Step-by-step explanation:

Subtract 8 from both sides of the equation.

2x+8=24

2x+8-8=24-8

Simplify

2x=16

Divide both side of the equation by the same term

2x/2 16/2

Answer:

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtract Property of Equality

Step-by-step explanation:

Step 1: Define

-6 = n/2 - 10

Step 2: Solve for n

Add 10 to both sides:                    4 = n/2Multiply 2 on both sides:              8 = nRewrite:                                          n = 8

Step 3: Check

Plug in n into the original equation to verify it's a solution.

Substitute in n:                   -6 = 8/2 - 10Divide:                                 -6 = 4 - 10Subtract:                             -6 = -6

Here we see that -6 does indeed equal -6.

∴ n = 8 is the solution to the equation.

Answer:

The range of the equation is y ≥ 9C

Step-by-step explanation:

The quadratic equation y = ax² + bx + c, represents by a parabola of vertex (h, k), where h = [tex]\frac{-b}{2a}[/tex] and k is the value of y at x = h

The range of the quadratic if it has a minimum vertex is y ≥ k, and y ≤ k if it has a maximum vertexThe parabola has a minimum vertex if the value of a is positive and a maximum vertex if the value of a is negative

∵ The equation is y = x² + 9

→ Compare it with the form above to find a and b

a = 1 and b = 0

a is a positive number

∴ The parabola has a minimum vertex

→ By using the 1st rule above

The range is y ≥ k

→ Use the rule of h above to find it

∵ h = [tex]\frac{-(0)}{2(1)}[/tex] = [tex]\frac{0}{2}[/tex]

h = 0

→ To find k substitute x by the value of h and y by k

∵ k = (0)² + 9

∴ k = 0 + 9

k = 9

The range of the equation is y ≥ 9

The lifetime for a certain type of tre has been shown to be five years the mean) with a standard deviation of 6 months. In a normal distribution, what percentage of these tires will
last more than six years (more than two standard deviations above the mean)?

Answers

Answer:

2.28%

Step-by-step explanation:

mean = 5 years = 60 months

standard deviation = 6 months

X = number of years the tires will last

P = probability of ...

z = z-score

6 years = 72 months

z = (# of months - mean) / standard deviation

z = (72 - 60)/6

z = 12/6

z = 2

P(X > 72) = 1 - P(X < 72)

= 1 - P(z < 2)    

(using a Standard Normal Probabilities Table we can see that P(z < 2) = .9772)

So:

= 1 - .9772

= 0.0228 OR 2.28%

[tex]x=29[/tex]

Step-by-step explanation:

The two pair of angles that are given values are supplementary, meaning they add up to [tex]180^{\circ}[/tex]. Therefore, we have the following equation:

[tex]2x-10+4x+16=180,\\6x+6=180,\\6x=174,\\x=\fbox{$29$}[/tex].

Answer:

[tex]\huge{ x=29° }[/tex]

Step-by-step explanation:

Here,

The two lines are parallel.

So,The angle (2x-10) and (4x+16) are corresponding. because these angles are the consecutive interior angles.

we know that,

Sum of corresponding angle =180°

According to the question,

[tex]\bold{(2x-10)+(4x+16)=180 }[/tex]

[tex]\bold{2x-10+4x+16=180 }[/tex]

[tex]\bold{ 6x+6=180 }[/tex]

[tex]\bold{6x=180-6 }[/tex]

[tex]\bold{ 6x=174 }[/tex]

[tex]\bold{ x=\dfrac{174}{6} }[/tex]

[tex]\bold{ x=29 }[/tex]

so,

value of x=29°
