Whats 345*28923+808(2829)=
RoseWind [281]

Hi there!

345*28923+808(2829)

The first step put the problem into 2 parts, the first part is 345*28923

The second part is 808(2829)

The parentheses means to multiply that number that it touches.

Add the final 2 answers.

345*28923 = 9,978,435

808(2829) = 2,285,832

Now, add the answers.

9,978,435 + 2,285,832 = 12,264,267

Hope this helped!~

Write the equation of the line described in point-slope form. Then, change to Standard Form. Contains points (3/2,-1/2) and (-1/
larisa [96]
Slope point form :
To put in slope point form, label any of the points as either X1,y1 and X and y, then plug in those values into the following equation form.
Y - y1 = m(X-X1)

But before, we must solve for the m value or slope.
M = y2-y1/x2-X1
M = 5/2 - -1/2 / -1/2 - 3/2.
M = 5/2 + 1/2 / -(1/2+3/2)
M = 6/2 / -(4/2)
M = 3/-2

Now we can place it in slope point and also in standard form of a line.

Y-y1 = m(X -X1)

Y - -1/2 = -3/2(X - 3/2)

Y + 1/2 = -3/2(X - 3/2)

This is in slope point form.

Y + 1/2 = -3/2x + 9/4
Y + 1/2 - 1/2 = -3/2x + 9/4 - 1/2
1/2 = 2/4
Y = -3/2x + 7/4
-3/2x = -6/4x
Y = -6/4x + 7/4
Y • 4 = 4( -6/4 X + 7/4)
4y = -6x + 7
4y + 6x = -6x + 6x +7

6x + 4y = 7

This is in standard form. If you have any questions of the steps just ask.

HIGHSCHOOL ALGEBRA!!!!! PLS HELP :) <br> Find the root of the equation: (6x–1)(6x+1) - 4x(9x+2) = −1
My name is Ann [436]

(6x–1)(6x+1) - 4x(9x+2) = −1

Simplify the left side:

36x^2-1 -36x^2-8x = -1

Combine like terms:

-1 -8x = -1

Add 1 to both sides:

-8x = 0

Divide both sides by -8:

x = 0 / -8

x = 0

The root is 0
