Y = -1/2x + 6.....the slope is -1/2 and the y int = 6 or (0,6)
y - y1 = m(x - x1)
slope(m) = -1/2
(0,6)....x1 = 0 and y1 = 6
now we sub
y - 6 = -1/2(x - 0) <==
** You basically just label ur variables and sub them into the point slope form
Answer:
B = 22
C = 122
D = 36
Step-by-step explanation:
The angles of a triangle add to 180. Take the measure of each angle add them together. Set them equal to 180.
2x + x + 4 + 7x - 4 = 180
10x = 180
x = 18
To find each angle, substitute x = 18.
Angle B is 18 + 4 = 22
Angle C is 7(18) - 4 = 122
Angle D is 2(18) = 36
Answer:

Step-by-step explanation:
step 1
Find the slope of the line that is perpendicular to the given line
we have
-----> given line
The slope of the given line is

Remember that
If two lines are perpendicular, then their slopes are opposite reciprocal
therefore
The slope of the line that is perpendicular to the given line is

step 2
Find the equation of the line in slope intercept form

we have

substitute

solve for b

therefore

Answer:
$21.85
Step-by-step explanation
the equation would be
4.95b+3.50c
b= the number of books (3)
c= the number of candles (2)
plug in the numbers
4.95(3)+3.50(2)=21.85
