Answer:
rose$7 shrub $11
Step-by-step explanation:
5r+3s=68
1r+14s=161
I will multiply the second by -5 to eliminate r variable
5r+ 3s= 68
-5r- 70s = -805
-67s = -737
Divide both by -67
s= 11
14*11=154
161-154 =7
5*7 + 3*11 = 68
35+33 = 68
7+ 14*11 = 161
7+154 = 161
Answer:
<h3>-6</h3>
Step-by-step explanation:
Let the slope of the first line be m1
Let the slope of the second line be m2
If both lines are perpendicular, then;
m1m2 = -1
Get m1, the slope of the line passing through A (-2, 0) and B (2,-k).
m1 = y2-y1/x2-x1
m1 = -k-0/2-(-2)
m1 = -k/4
Get the slope of the line 3y + 2x = 5
Rewrite the equation;
3y = -2x + 5
y = -2/3 x + 5/3
Hence the slope of the line m2 is -2/3
Since m1m2 = -1, then;
-k/4(-2/3) = -1
2k/12 = -1
k/6 = -1
k = -6
Hence the value of k is -6
