Answer:
36 trees were infected with the virus.
Step-by-step explanation:
Given:
Total number of trees = 90
Percentage of tree that had virus 40%
To find:
Number of tress that were infected by virus = ?
Solution:
Let the number trees that was affected by the virus be X.
then
X = 40% of 90
X =
X =
X= 36
The slope-intercept form of the equation of the line described is y = 3/4x - 4.
<h3>What is a slope?</h3>The slope of a line simply refers to the gradient of a line and it's typically used to describe both the ratio, direction and steepness of an equation of a straight line.
<h3>How to calculate the slope of a line?</h3>Mathematically, the slope of a straight line can be calculated by using this formula;
Mathematically, the standard form of the equation of a straight line is given by;
y = mx + c
Where:
The partial equation for the perpendicular line is given by:
y = 3/4x + c
At point (8, 2), we have:
2 = 3/4(8) + c
2 = 6 + c
c = 2 - 6
c = -4.
Therefore, the slope-intercept form of the equation of the line described is y = 3/4x - 4.
