Answer:
y = -0.5x -2
Step-by-step explanation:
We have to find a line perpendicular to the line y = -2x -3.
Let the required line will have slope m so ,
-2m = 1
m = -0.5.
So, the required line will have the slope -0.5.
Now, let the line be y = -0.5x + c.
This line is passing through (-2,-1), So putting this point in the line we will get
-1 = 1 + c
c = -2 .
So, the required line is
y = -0.5x -2.
Answer:
x = 10
Step-by-step explanation:
We can use the Angle Bisector of a triangle and proportions to solve this problem. Put the smaller triangle over the larger triangle.
AB x+4
------ = ----------
AC 2x+1
8 x+4
------ = ----------
12 2x+1
Using cross products
8(2x+1) = 12(x+4)
Distribute
16x+8 = 12x+48
Subtract 12x from each side
16x-12x +8 = 12x-12x+48
4x +8 = 48
Subtract 8 from each side
4x+8-8 = 48-8
4x = 40
Divide by 4
4x/4 =40/4
x = 10
69 - 3a = 0
69 - 3a (-69) = 0 (-69)
-3a = -69
-3a(/-3) = -69(/-3)
a = 23
hope this helps
