To obtain the rate of change of mine's silver output, subtract the number of silver exported on 2005 from that on 2008. From the given, from 2005 to 2008, which is a span of 3 years, the exported silver decreased by 175 tons. Thus, the rate of change is equal to -175 tons per 3 years.

Find the equation of the line through point (2,2) and parallel to y=x+4. Use a forward slash (i.e.”/“) for fractions (e.g. 1/2 f
aleksandr82 [10.1K]

Answer:

The equation of the line is, y = x

Step-by-step explanation:

The constraints of the required linear equation are;

The point through which the line passes = (2, 2)

The line to which the required line is parallel = y = x + 4

Two lines are parallel if they have the same slope, therefore, we have;

The slope of the line, y = x + 4 is m = 1

Therefore, the slope of the required line = 1

The equation of the required lime in point and slope form becomes;

y - 2 = 1 × (x - 2)

∴ y = x - 2 + 2 = x

The equation of the required line is therefore, y = x

The sum of three consecutive odd integers is -111 , find the three integers
Nadusha1986 [10]

Answer:

-39, -37, -35

Step-by-step explanation:

3x + 6 = -111

3x = -111 - 6

3x = -117

x = (-117)/3

x = -39

x + 2 = -37

x + 4 = -35
