Olve for x. 3(3x - 1) + 2(3 - x) = 0 x = 3/7 x = -3/7 x = 1/3 x = -1/3

zloy xaker [14]

<u>Answer:</u>

x = -3/7

<u>Step-by-step explanation:</u>

We are given the following equation for which we have to solve for x:

$3(3x - 1) + 2(3 - x) = 0$

So we will start by expanding the equation by multiplying the common factor with the brackets to get:

$9x-3+6-2x=0$

Arranging the like terms together (variables on one side of the equation and constants on the other side) to get:

$9x-2x=3-6\\\\7x=-3\\\\x=-\frac{3}{7}$

Therefore, x = -3/7.

The points (4,7) and (r. – 5) lie on a line with slope – 3. Find the missing coordinate r

dusya [7]

Answer:

$r=\frac{14}{3}$

Step-by-step explanation:

Set up an equation and solve for r using the formula for slope:

$\frac{5-7}{r-4}=-3\\ \\-2=-3(r-4)\\\\-2=-3r+12\\\\-14=-3r\\\\\frac{14}{3}=r$

-HELP! Look at the picture below and answer correctly so i can mark you as brainliest.

The y-intercept is 50 and it tells how many chocolates he starts off with. The slop is -4 because that is how many chocolates he gives out each week. y=-4x+50

Answer:

3x^7 / y

Step-by-step explanation:

√63x^15y^9/√7xy^11

= √ [(63/7) x^(15-1) y^(9-11)

= √9x^14y^-2

= √9x^14 / y^2

= 3x^7 / y
