The answer is 50
BEC=25
BC=12.5 (half of 25)
12.5 x 4 (number of triangles)=50
Answer:
The slope-intercept form:
Step-by-step explanation:
-To get the slope-intercept equation, you first need to find the slope by using this equation (starting counting from the first point, to the second point) in order to get the slope. After you have the slope, you need to find the y-intercept ( y-intercept is where the line crosses the y axis of the graph, basically). So, to find that, you need look for the point that only crosses the y axis to get the y-intercept. After you have both the slope and y-intercept, you put it in slope-intercept form:
The two points I found from the following graph are:
and
Trick: Since the line of the graph shows that it is down (not up), Start counting down from point to point . Then, find the y-intercept:
Use it to create a slope-intercept form:
(where represents the slope and represents the y-intercept)
So, therefore the slope-intercept form is .
Answer:
=
Step-by-step explanation:
Given parameters.
Required
Determine
Reference to , we have:
Apply trigonometry ratio of cosine
Substitute values for Adjacent and Hypotenuse
Rationalize:
=
Y = mx + b
slope = m = 1/21, so we have
y = 1/2 x + b
The line passes through (2, 5), so we get
5 = 1/2 * 2 + b
5 = 1 + b
b = 4
The equation of the line is
y = 1/2 x + 4
Point (x, 3) has a y-coordinate of 3. We are looking for the x-coordinate.
y = 1/2 x + 4
3 = 1/2 x + 4
-1 = 1/2 x
x = -2
