Answer:

7

Step-by-step explanation:

Replace the variations with given values: z = 9 and y = 6

\frac{ {z}^{2} - 3y }{z}  \\   \frac{ {9}^{2} - 3 \times 6 }{9}  =  \frac{81 - 18} {9}  \\  \frac{63}{9}  = 7

Write the equation of a line that passes through the points (−3, 7) and (3, 3)
Dennis_Churaev [7]

Step-by-step explanation:

You can write an equation of a line conveniently by point-slope form. It's in the form of y -a = m(x -b) where (b,a) is the coordinates of a point that's on the line and m is the slope of the line.

Now choose a point (It doesn't really matter which one) and plug that in the equation. I'll choose (-3,7) where a = 7 and b = -3

y -a = m(x -b) \\ y -7 = m(x -(-3)) \\ y -7 = m(x +3)

The next thing we have to do now is finding the slope, m, where it's equal to \frac{y_{2} -y_{1}}{x_{2} -x_{1}}\\. I'll make (-3,7) point 1 and (3,3) point 2.

m = \frac{3 - 7}{3 -(-3)} \\ m = \frac{3 - 7}{3 +3} \\ m = \frac{-4}{6} \\ m = -\frac{2}{3}

Now let's plug that to our equation.

y -7 = m(x +3) \\ y -7 = -\frac{2}{3}(x +3)

Now we have the equation but out of all the choices it seemed that all of them are in slope-intercept form all you have to do now is make our equation rewrite it in slope-intercept form.

y -7 = -\frac{2}{3}(x +3)\\ y -7 = -\frac{2}{3}x -\frac{2}{3}(3) \\ y - 7 = -\frac{2}{3}x -2\\ y = -\frac{2}{3}x +5

<h3>Answer:</h3>

y = -\frac{2}{3}x +5\\ is your equation.

Pls help math question i wil make brainliest
AVprozaik [17]

Answer:

(41/12)g+-23/12

Step-by-step explanation:

3(5g−1) /4 - (2g+7)/6

(15g-3)/4 - (2g+7)/6---> distributive property

3(15g-3)/12 - 2(2g+7)/12--->make the denominators same

(45g-9)/12 - (4g+14)/12---distributive property

Gregory drinks 6 liters of water over 2 days. In how many days would he consume another 12 liters?
DanielleElmas [232]

Answer:

4 days

Step-by-step explanation:

If he consumed 6 liters in two days, that would mean he would have consumed 3 liters per day. You would divide 12 by 3, since he drinks 3 liters per day, and after 4 days, he would have consumed 12 liters.
