Answer:

The standard general equation for a straight line is:

y = mx + C. You said the slope of line is 2/3. m is always the slope in this context. So with the numerical value slope we have the line

Y = 2/3 X + C. You also said the line passes through the point (1, -4) that is the X value is 1 and the y value is -4. Substitute these value into the linear equation to find C, as follows

-4 = 2/3 + c. and so C = - 4 - 2/3 = -14/3 and so the equation of line is :

y = 2x/3 + 14/3 or if you like 3y = 2x + 14

It is important to remember that the convention of the bracketted numbers e.g. (1,-4) or ( 1, -4, z), say is that the first number in the brackets indicates the X value, the second the y value and the third, the z value in the case of 3 D coordinates.

Answer:

[tex]f(x)=(x-3)(x^2-8x+17)[/tex]

Or:

[tex]f(x)=x^3-11x^2+41x-51[/tex]

Step-by-step explanation:

To find our factors, we can work backwards.

We know that 3 is a zero. This means that:

[tex]x=3[/tex]

Subtract 3 from both sides:

[tex](x-3)=0[/tex]

So, (x-3) is one of our factors.

We also know that (4+i) is a zero. So:

[tex]x=4+i[/tex]

First, let’s isolate the imaginary. So, subtract 4 from both sides:

[tex](x-4)=i[/tex]

Now, let’s square both sides:

[tex](x-4)^2=(i)^2[/tex]

Expand the left. Evaluate the right:

[tex](x^2-8x+16)=-1[/tex]

Add 1 to both sides. So, our factor is:

[tex](x^2-8x+17)=0[/tex]

Hence, our polynomial function is:

[tex]f(x)=(x-3)(x^2-8x+17)[/tex]

This is also the least degree since we did the most minimum we can do to solve backwards.

Further Notes:

If we want to convert this to standard form, we can distribute:

[tex]f(x)=(x^3-8x^2+17x)+(-3x^2+24x-51)[/tex]

Combining like terms will yield:

[tex]f(x)=x^3-11x^2+41x-51[/tex]

Answer:

It is always positive because the discriminant is negative and therefore has no roots. This can also be interperted as the equation will always be above the x-axis on the parabola and therefore always be positive.

Step-by-step explanation:

The value of the quadratic expression (x - 4)² + 4 will be always positive.

Let the point (h, k) be the vertex of the parabola and a be the leading coefficient. Then the equation of the parabola will be given as,

y = a(x - h)² + k

The quadratic expression is given below.

⇒ x² - 8x + 20

Convert the expression into a vertex form, then we have

⇒ x² - 8x + 16 + 4

⇒ (x² - 2 · x · 4 + 4²) + 4

⇒ (x - 4)² + 4

Thus, the value of the expression (x - 4)² + 4 will be always positive.

Answer:

1/4

Step-by-step explanation:

If you type cos(75)cos(15) into a scientific calculator, the answer comes out as 1/4.

The value of the trigonometric expression cos(75)cos(15) is 1/4 after applying the trigonometric identity.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have a trigonometric expression:

= cos(75°)cos(15°)

As we know the trigonometric identity:

cos(a)cos(b) = (1/2)[cos(a + b) + cos(a - b)]

a = 75

b = 15

Plug the above values in the trigonometric identity:

cos(75)cos(15) = (1/2)[cos(75 + 15) + cos(75 - 15)]

cos(75)cos(15) = (1/2)[cos(90) + cos(60)]

The trigonometric ratio is the ratio of the pair of a right-angled triangle.

The value of cos90 = 0

cos60 = 1/2

cos(75)cos(15) = (1/2)[0 + 1/2]

cos(75)cos(15) = 1/4

Thus, the value of the trigonometric expression cos(75)cos(15) is 1/4 after applying the trigonometric identity.

Answer:

Step-by-step explanation:

C

the equation would be y=2x+4

The solution is Option C.

The linear equation is given as y = 2x + 4

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

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

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the x values be = { -4 , -2 , 0 , 2 }

Let the y values be = { -4 , 0 , 4 , 8 }

The slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 0 - ( -4 ) / ( -2 - ( - 4 ) )

On simplifying the equation , we get

Slope m = 4/2 = 2

Now , the equation of line is

y - y₁ = m ( x - x₁ )

Substituting the values in the equation , we get

y - 0 = 2 ( x - ( -2 ) )

On simplifying the equation , we get

y = 2x + 4

Hence , the linear equation is y = 2x + 4
