Simplify and write answer in standard form.

mamaluj [8]

Answer:

$x^3+8x^2+2x+1$

Step-by-step explanation:

Combine like terms (terms with the same exponent).

$x^3+(3x^2+5x^2)+(x+x)+1=x^3+8x^2+2x+1$

"Standard form" means to list terms so the exponents go from high to low (descending order).

Answer:

d =7.6

Step-by-step explanation:

$(-3,11) =(x_1,y_1)\\(-6,4)=(x_2,y_2)\\\\\mathrm{Compute\:the\:distance\:between\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\\\quad \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}\\\\=\sqrt{\left(-6-\left(-3\right)\right)^2+\left(4-11\right)^2}\\= \sqrt{(-6+3)^2+(4-11)^2}\\ \\d= \sqrt{(-3)^2+(-7)^2} \\\\d = \sqrt{9+49}\\ \\d = \sqrt{58}\\\\d = 7.61577\\\\d =7.6$

The graph of F(x) shown below resembles the graph of G(x) = x ^ 2 but it has been changed somewhat . Which of the following coul

Lorico [155]

Answer:

f(x) = 3 $x^{2}$ + 2

Step-by-step explanation:

I think your question missed key information, allow me to add in and hope it will fit the orginal one because I answered this question once in Brainly as well. Please have a look at the attached photo.

My answer:

Given G(x) = $x^{2}$

As we can see, the graph of f(x) is 2 units above the graphof g(x) in vertical (vertical shift)

=> f(x) = a $x^{2}$ + 2

As you can see, the graph of f(x) is stretched vertically by a dilation factor of 3 and there is no reflection, so a= 3

=> the equation of f(x) is: f(x) = 3 $x^{2}$ + 2

Hope it will find you well.

Write each fraction number as a decimal 33/40

Gnom [1K]

Answer:

0.825

Step-by-step explanation:

In order to make the denominator 100, we must multiply both the numerator and denominator by 2.5

33*2.5 = 66 + 16.5 = 82.5

33/40 = 82.5/100

Now we solve, 82.5/100 = 0.825

Identify the slope and y intercept of 4x + 2y = 8

Sergeu [11.5K]

Answer:

The slope is -2

and the 'y' intercept point is 4

Step-by-step explanation:

First lets start by writing the given equation in slope-intercept form, by isolating 'y' variable

y=4-2x

Since in this form, the slope of the line is the coefficient of 'x'. our slope is -2

and the 'y' intercept point is 4
