Answer:

The simplified expression is:

$\frac{2}{5}y+\frac{1}{5}x-0.2y-6+\left(-2\right)=0.2y+0.2x-8$

Step-by-step explanation:

Given the expression

$\frac{2}{5}y+\frac{1}{5}x-0.2y-6+\left(-2\right)$

$\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a$

$=\frac{2}{5}y+\frac{1}{5}x-0.2y-6-2$

$\mathrm{Group\:like\:terms}$

$=\frac{2}{5}y-0.2y+\frac{1}{5}x-6-2$

Add similar elements

$=0.2y+\frac{1}{5}x-6-2$

$=0.2y+\frac{x}{5}-6-2$

$=0.2y+\frac{x}{5}-8$

$=0.2y+0.2x-8$

Thus, the simplified expression is:

$\frac{2}{5}y+\frac{1}{5}x-0.2y-6+\left(-2\right)=0.2y+0.2x-8$

I need help graphing 2x - 6y = 42 I'm just really lazy

solong [7]

Answer:

We can use slope intercept form to get the points needed. Y= -7+1/3x The points are (0,-7) and (3,-6)

Step-by-step explanation:

Subtract 2x from the left side and place it over to the right side with the 42. Now we have -6y= 42-2x. From here we divide by -6 and we get y= -7+1/3x. We know that are slope is 1/3 which the one is the rise and the 3 is the run. We also know that our y intercept is -7. We plot the points at (0,-7) and (3,-6)

Which of the following changes in the price index produces the greatest rate of inflation: 106 to 112, 112 to 118, or 118 to 124

boyakko [2]

Answer:

Step-by-step explanation:

firstly you have to find the rate of change of the various price index in percentage.

A, From 106 to 112:

we find the difference 112-106 = 6

then the rate of change = 6/106 * 100 = 5.66%.

B ,From 112 to 118:

we find the difference 118-112 = 6

then the rate of change = 6/118 * 100 = 5.36%.

C ,From 118 to 124:

we find the difference 124-118 = 6

then the rate of change = 6/124 * 100 = 5.08%.

we can see that the price index with the greatest percentage is A.
