Answer:

Y= 5x-6

Step-by-step explanation:

The slope intercept form is y=mx+b. The m stands for your slope. The b stands for the y-intercept. So, plug in the slope of 5 for m, then plug in -6 of b and then your equation should end up as y=5x-6. Hope this helps :)

Answer:

D. The axis of symmetry is x = 1.5 and the vertex is (1.5, 0).

Step-by-step explanation:

y=4x^2-12x+9:\quad \mathrm{Parabola\:with\:vertex\:at}\:\left(h,\:k\right)=\left(\frac{3}{2},\:0\right),\:\mathrm{and\:focal\:length}\:|p|=\frac{1}{16}

To find the vertex of this parabola, "complete the square:"  Rewrite y = 4x2 - 12x + 9 in the form y = 4(x - h)^2 + k:

y = 4x^2 - 12x + 9  =>  y = 4(x^2 - 3x) + 9.

Now complete the square of x^2 - 3x:  Take half of -3 and square the result, obtaining (-3/2)^2, or 9/4.  Add 9/4 to x^2 - 3x and then subtract 9/4 from the result:  We get x^2 - 3x + 9/4 - 9/4.  Substitute this result back into

y = 4(x^2 - 3x) + 9:  y = 4(x^2 - 3x + 9/4 - 9/4) + 9

and then rewrite the perfect square x^2 - 3 + 9/4 as the square of a binomial:

                                y = 4(x - 3/2)^2 - 9/4) + 9.  This simplifies to:

                                y = 4(x - 3/2)^2 + 0.

Thus, the vertex is at            (3/2, 0) and the axis of symmetry is x = 3/2.  This agrees with Answer B.

Given : equation y = 4x^2 − 12x + 9

To Find  :

A) The axis of symmetry is x = 0 and the vertex is (0,9).

B)The axis of symmetry is x= 1.5 and the vertex is (1.5, 0).

C)The axis of symmetry is x = 4 and the vertex is (4, -12).

D)The axis of symmetry is x = -1.5 and the vertex is (-1.5, 36).

Solution:

y =  4x² - 12x  + 9

=> y = (2x)² - 2(2x)3  + 3²

=> y = (2x - 3)²

=> y = 4(x - 3/2)²

=> y = 4(x - 1.5)²

Axis of symmetry is x= 1.5  

Vertex  = (1.5 , 0)

The axis of symmetry is x= 1.5 and the vertex is (1.5, 0).

Answer:

10

Step-by-step explanation:

f(x)=f(6) means x=6

Now, as 6>3 we use the formula for x>3

Substituting 6 into 1/2x+7 we get,

1/2(6)+7

=3+7

=10

The value of function at x= 6 is 10.

A piecewise-defined function in mathematics is one that is composed of several smaller functions, each of which has a certain interval of the domain it applies to. Instead of being a property of the function itself, piecewise definition is a means to express the function.

We have,

f(x) = 3x -1 , x<3

1/2x + 7, x>3

Now, for x = 6 which falls in condition x>3

f(6) = 1/2(6)+ 7

f(6) = 3 + 7

f(6)= 10

Step-by-step explanation:

Add like terms. Real terms are added; imaginary terms are added.

  (√3 -i) + (2-√3i) = (√3 +2) +(-i -√3i)

  = (√3 +2) -i(1 +√3) . . . . . the common factor of -i can be factored out

Answer is y = 25/4

Answer:

$58,560

Step-by-step explanation:

First step: set up your proportion equation. Keeping the percents on the bottom, I set it up as $48,000/100% = $x/122%. I'm writing it as 122% rather than 22% so we don't have to add the increase in price to the original price later. You can see that, in order to get from 100 to 48,000, you need to multiply by 480, so you can do this to 122 to get x. Your teacher might, instead, want you to cross multiply. Do what's expected of you. Either way, your result should be $58,560. Check that it makes sense by checking that it's an increase and that it looks reasonable for the amount of the increase and you're done.

The speed of the plane is the rate of change of distance over time

The speed of the plane should be 453.65 mph southwest

The speed of the wind is given as:

[tex]\mathbf{S_w = 38.7mph}[/tex]

The expected speed of the plane is:

[tex]\mathbf{S_s = 452mph}[/tex]

So, the actual speed is calculated using the following Pythagoras theorem

[tex]\mathbf{S_{sw}^2 = S_w^2 + S_s^2}[/tex]

This gives

[tex]\mathbf{S_{sw}^2 = 38.7^2 + 452^2}[/tex]

[tex]\mathbf{S_{sw}^2 = 205801.69}[/tex]

Take square roots of both sides

[tex]\mathbf{S_{sw} = 453.65}[/tex]

Hence, the speed of the plane should be 453.65 mph southwest

Answer:

12x² +3x = 96

Step-by-step explanation:

x = 4(x + 3)( 3x - 8)

x =  (4x + 12) (3x - 8)

x = 4x(3x - 8) + 12(3x - 8)

x = 12x² - 32x + 36x - 96

x = 12x² + (-32x + 36x) - 96

x = 12x² + 4x - 96

0 = 12x² + 4x -x - 96

0 = 12x² + 3x -96

96 = 12x² + 3x  same as 12x² +3x = 96

[tex]\sf\longmapsto \dfrac{(x + 1) - 2(3x - 3)}{10} = 2[/tex]

[tex]\sf\longmapsto \dfrac{x + 1 - (6x - 6)}{10} = 2[/tex]

[tex]\sf\longmapsto \dfrac{x + 1 - 6x + 6}{10} = 2[/tex]

[tex]\sf\longmapsto - 5x + 7 = 20[/tex]

[tex]\sf\longmapsto - 5x = 20 - 7[/tex]

[tex]\sf\longmapsto - 5x = 13[/tex]

[tex]\sf\therefore x = - \dfrac{13}{5} [/tex]

Hence, the value of x will be -13/5 respectively.

[tex]\frac{x + 1}{10} - \frac{3(x - 1)}{5} = 2 \\ [/tex]

[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]

[tex]\frac { x + 1 } { 10 } - \frac { 3 ( x - 1 ) } { 5 } = 2 \\ \frac { x + 1 } { 10 } - \frac { 3 ( x - 1 ) } { 5 } = \frac{2}{1} [/tex]

Take a look at the denominators. The denominators are 10, 5 & 1. Their LCM is 10. So, multiply the fractions on both the sides of the equation by 10.

[tex]\frac { x + 1 } { 10 } - \frac { 3 ( x - 1 ) } { 5 } = \frac{2}{1} \\ \frac{x + 1}{10} \times \frac{1}{1} - \frac{3x - 3}{5} \times \frac{2}{2} = \frac{2}{1} \times \frac{10}{10} \\ \frac{x + 1}{10} - \frac{6x - 6}{10} = \frac{20}{10} [/tex]

Now cancel the denominators (as they have the same value) & take the numerators.

[tex]x + 1 - (6x - 6) = 20 \\ [/tex]

Now, simplify it.

[tex]x + 1 - (6x - 6) = 20 \\ x + 1 - 6x + 6 = 20 \\ x - 6x + 1 + 6 = 20 \\ - 5x + 7 = 20 \\ - 5x = 13 \\ x = -\frac{13}{5} \\ \boxed{ \boxed{ \bf x = - \frac{13}{5} =\: - 2 \frac{3}{5} = - 2.6}}[/tex]
