From your work on parts (a) and (b), you know that
.. r = 3.50
.. s = 140
The composite index of production cost from 2007 to 2009 is 114.2.

(c) If the production cost in 2007 was RM50, then in 2011 it was
.. RM50 * (2009 index) * (2011 index) = RM50 * 1.142 * 1.200 = RM68.52

Find the slope of the line passing through the points (-5, 3) and (7,9).

dybincka [34]

Answer:

$\huge\boxed{slope=\dfrac{1}{2}=0.5}$

Step-by-step explanation:

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points

$(-5;\ 3)\to x_1=-5;\ y_1=3\\(7;\ 9)\to x_2=7;\ y_2=9$

Substitute:

$m=\dfrac{9-3}{7-(-5)}=\dfrac{6}{7+5}=\dfrac{6}{12}=\dfrac{6:6}{12:6}=\dfrac{1}{2}$

How many soultions does 5(x-3)+6=5x-9

olya-2409 [2.1K]

5(x - 3) + 6 = 5x - 9 has no solution

<em><u>Solution:</u></em>

We have to find the number of solutions for the given equation

Given equation is:

5(x - 3) + 6 = 5x - 9

Multiply the terms inside with bracket with constant outside the bracket

5x - 15 + 6 = 5x - 9

Add the constants in left hand side of equation

5x - 9 = 5x - 9

If the coefficients are the same on both sides, then the sides will not equal, therefore no solutions will occur.

Here, 5x - 9 = 5x - 9

The coefficients are same in both sides of equation

Therefore, the equation has no solution
