Step-by-step explanation:

[tex]12x {}^{2} + 4x - 3x - 1 = 0 [/tex]

[tex]4x \times (3x + 1) - (3x + 1) = 0[/tex]

[tex](3x + 1) \times (4x - 1) = 0[/tex]

[tex]3x + 1 = 0 \\ 4x - 1 = 0[/tex]

[tex]x = - \frac{1}{3} \\ x = \frac{1}{4} [/tex]

I hope this helps :)

For the graph of the function, identify the axis of symmetry, vertex and the formula for the function.


A. Axis of symmetry: x = 0.5; Vertex: (0.5, –0.75); f(x) = –x2 – x – 1


B. Axis of symmetry: x = 0.5; Vertex: (0.5, –0.75); f(x) = –x2 + x – 1


C. Axis of symmetry: x = –0.5; Vertex: (–0.5, –0.75); f(x) = –x2 + x – 1


D. Axis of symmetry: x = 0.5; Vertex: (0.5, –0.75); f(x) = –x2 + 2x – 1

Answers

Answer:

Axis of symmetry: x = 0.5; Vertex: (0.5, –0.75); f(x) = –x2 + x – 1

Step-by-step explanation:

The answer is A because the axis of symmetry is in between 0 and 1, the vertex lies on 0.5 and -0.75, and the parabola opens down so the coefficient of a is -1, and the y-int or the value of c is -1

The vertex of the function is  axis of symmetry is  and the formula for the function is  Option (a) is correct.

Further Explanation:

Given:

Calculation:

The standard form of the parabola is shown below.

Here, the parabola has vertex at  and has the symmetry parallel to x-axis and it opens left.

The general form of the parabola can be expressed as follows,

The graph is a downward parabola.

From the graph it has been observed that the vertex of the parabola is

Symmetry of the graph is  

The -intercepts of the graph is  Therefore, the value of is  

The value of  is -1 as the graph is a downward parabola.

The vertex of the function is  axis of symmetry is  and the formula for the function is  Option (a) is correct.

Step-by-step explanation:

To find the slope through 2 points

m = ( y2-y1)/(x2-x1)

    = -1/0

Since it is a number divided by zero, the slope is undefined

In which quadrant is the point (-5, -4) in?

III
IV
II
I

Answers

Answer:

quadrant 3

Step-by-step explanation:

only quadrant 3 contains both negative values for x & y

Answer:

III

Step-by-step explanation:

First, remember the order of the quadrants; quadrant I is in the top right corner then the quadrants increase moving counterclockwise. So, the third quadrant is the bottom left. Each quadrant consist of (x,y) values of different signs.

They are as follows:

I - (x,y)

II - (-x,y)

III - (-x,-y)

IV - (x,-y)

Since, (-5,-4) has two negative coordinates, it must be in the III quadrant.

what is the remainder of f(x)=x^4-2x^3-27x^2-9x+18 when divided by binomial x+4

Answers

Answer:

The remainder will be 6.

Step-by-step explanation:

We have the function:

[tex]f(x)=x^4-2x^3-27x^2-9x+18[/tex]

And we want to find the remainder after it is divided by the binomial:

[tex]x+4[/tex]

We can use the Polynomial Remainder Theorem. According to the PRT, if we have a polynomial P(x) being divided by a binomial in the form (x - a), then the remainder will be given by P(a).

Here, our divisor is (x + 4). We can rewrite this as (x - (-4)).

Therefore, a = -4.

Then according to the PRT, the remainder will be:

[tex]f(-4)=(-4)^4-2(-4)^3-27(-4)^2-9(-4)+18=6[/tex]

The remainder will be 6.

A rectangle has an area of square unit inside length of 2 1/4 unit find the other side length of the Rectangle

Answers

Answer:

Therefore, the other side length of the Rectangle b = 4 (4/9)

Step-by-step explanation:

Although crucial information that area of the rectangle is missing we can assume it be 10 square units for understanding purposes.

Let the sides of the rectangle be a and b.

Given a = 2 1/4 units

a = 9/4 units

b=?

Area of a rectangle = product of its sides = a×b

⇒ a×b= 10

⇒ 9b/4 = 10

⇒ b= 40/9 = 4 (4/9)

Therefore, the other side length of the Rectangle b = 4 (4/9)

I think you really want the second line, but one can't be sure.

Write the equation of a line passing through (-4.3) and perpendicular to -6x + 4y =-12.

Answers

Answer:

y=-2/3*x+1/3

Step-by-step explanation:

-6x+4y=-12

put into y=mx+b line equation

4y=6x-12

y=(6/4)x-(12/4)

y=(3/2)x-4

slope is 3/2

to find perpendiular line slope take the negative inverse.

-(2/3) = slope of perpendicular line

use line equation and solve for y-intercept (b)

3=(-2/3)*(-4)+b

3=8/3+b

b= 9/3-8/3 = 1/3 : 3 = 9/3 to allow for subrtaction of fractions.

a) what is the difference in temperatures between 7 am to 5 pm
b) which part of the day was the temperature rising the fastest a, b, c, d, or e?

Answers

Answers:

a) The difference in temperature is 25 degrees Fahrenheit. b) The temperature was rising fastest during interval 'a'

=========================================================

Explanations:

a) We subtract the y coordinates of the left and right endpoints. We get 65-40 = 25b) The fastest rising temperature will visually correspond to the steepest part of the curve. That would be region 'a'. After this interval, region b is still increasing, but not as much as the previous interval (since it's not as steep here). Then it gets less steep for region c, and d sort of flattens out as well. So during the morning hours it appears the temperature is going up the fastest.

x = 8, area = 364 km^2, perimeter = 80 km

Step-by-step explanation:

to start, we have to recognize that opposite sides of a rectangle are congruent.

therefore ➪

2x + 10 = 4x - 6

2x + 16 = 4x

16 = 2x

x = 8

now just plug that in and you'll find ➪

length = 26km

width = 14km

area = l * w

area = 26 * 14

area = 364 km^2

perimeter = 2(l + w)

perimeter = 2(14+26)

perimeter = 80 km
