I graphed the functions on the graph below so you can see that the horizontal translation is represented by 4.
Answer:
-3
Step-by-step explanation:
An increase in x-value from 9 to 10 is an increase of 1 unit. The slope of -7 tells you that the corresponding change in y will by -7 units:
v = 4 -7 = -3
The value of v is -3.
_____
<em>Alternate solutions</em>
You can see this easily on a graph, or you can use the equation of the line. We have a point and a slope, so the point-slope form is useful.
y = m(x -h) +k
y = -7(x -9) +4
For x=10, the value of y is ...
v = -7(10 -9) +4 = -7 +4
v = -3
0.486 % of world population lives in canada
<em><u>Solution:</u></em>
From given,
World population = 7691 million
Canada population = 37.4 million
We have to find the percent of world population lives in canada
Let "x" be the percent of world population lives in canada
Therefore, from question,
x % of world population = canada population
x % of 7691 = 37.4
<em><u>Solve the above equation for "x"</u></em>
Thus 0.486 % of world population lives in canada
