First find the slope
Y-y
----
X-x
2/3 is the slope
Next find the slope of the other line
-2y -3x=13
-2y=3x+ 13
Y=-2/3+-6.5
No the lines are perpendicular not parallel
Answer:
BC = 18.34°
Step-by-step explanation:
The secant- secant angle BAC is half the difference of the intercepted arcs, that is
( DE - BC) = 27.42
( 73.18 - BC ) = 27.42 ( multiply both sides by 2 )
73.18 - BC = 54.84 ( subtract 73.18 from both sides )
- BC = - 18.34° ( multiply both sides by - 1 )
BC = 18.34°
What number = x
x - 3.5 = 12.7
Isolate the x, add 3.5 from both sides
x - 3.5 (+3.5) = 12.7 (+3.5)
x = 12.7 (+3.5)
x = 16.2
16.2 is your answer
hope this helps
Answer:
D) 5
Step-by-step explanation:
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Divide 2 from all terms within the equation:
(2y)/2 = (10x - 8)/2
y = (10x)/2 - (8)/2
y = 5x - 4
Note the slope-intercept form:
y = mx + b
y = y
x = x
m = slope
b = y-intercept.
In this case, 5 is in place of m, or your slope.
D) 5 is your answer.
