1 answer:

7 0

      (7 m n) · (5 m² n)

      = 7 · m · n · 5 · m² · n

      =    7·5 · m·m² · n·n

      = 35   ·   m³   ·   n²

   35 m³ n²

Which of the following choices is a good estimate for the slope of the Line of Best Fit in the scatter plot?

svetoff [14.1K]

Answer:

A good estimate for the slope is 95/60

Step-by-step explanation:

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

From the graph take the points

(0,0) and (80,125)

substitute

$m=\frac{125-0}{80-0}$

$m=\frac{125}{80}$

simplify

$m=\frac{25}{16}$

Multiply by 3.75 both numerator and denominator

$m=\frac{25*3.75}{16*3.75}$

$m=\frac{93.75}{60}$

$m=\frac{94}{60}$

therefore

A good estimate for the slope is 95/60

-2(z+3)-z=-z-4(z+2)<br> solve for z quickly please! will give brainliest

anyanavicka [17]

Answer:

$\sf z = - \dfrac{2}{3}$

Step-by-step explanation:

Solve for z:

$\longrightarrow$ -2(z + 3) = -z - 4(z + 2)

-4(z + 2) = -4z - 8:

$\longrightarrow$ -2(z + 3) = -z -4z - 8

Grouping like terms, -z - 4z - 8 = (-z - 4z) - 8:

$\longrightarrow$ -2(z + 3) = (-z - 4z) - 8

-z - 4z = -5z:

$\longrightarrow$ -2 (z + 3) = -5z - 8

Expand out terms of the left hand side:

$\longrightarrow$ -2z - 6 = -5 z - 8

Add 5z to both sides:

$\longrightarrow$ (5z - 2z) - 6 = (5z - 5z) - 8

5z - 5z = 0:

$\longrightarrow$ (5z - 2z) - 6 = -8

5z - 2z = 3z:

$\longrightarrow$ 3z - 6 = -8

Add 6 to both sides:

$\longrightarrow$ 3z + (6 - 6) = 6 - 8

6 - 6 = 0:

$\longrightarrow$ 3z = 6 - 8

6 - 8 = -2:

$\longrightarrow$ 3z = -2

Divide both sides of 3z = -2 by 3:

$\longrightarrow$ $\sf \dfrac{3}{3}z = - \dfrac{2}{3}$

$\sf \dfrac{3}{3} = 1 :$

$\longrightarrow$ $\sf z = - \dfrac{2}{3}$
