The slope of two lines are - 3/2 and 18/a. Determine the value of α that will make the lines:
1 answer:
Answer:
a) a=-12
b) a=27
Step-by-step explanation:
a) parallel lines have = slopes SO
-3/2 = -3/2
-3/2 = 18/a
-3a/2 = 18
-3a = 18 * 2 = 36
a = -12
b) perpendicular lines have negative inverse slopes SO
- 3/2 ---> 2/3
2/3 = 18/a
2a/3 = 18
2a = 18 * 3 = 54
a = 54/2 = 27

Answer:
answer = 7000
Step-by-step explanation:
let the number be X
therefore, 91% × X = 637
or. 91 / 100 × X = 637
or. x = 637 × 100 ÷ 91
or. x = 700
The answer for this will be
2a(1-2a ²+3bc)
Answer:
160 is a whole angle so 37+72=109 160-109=51
51 is your answer
Step-by-step explanation:
First you add 3+6, then take 9 and multiply by 2 which is 18, the do 26-18 which is 8×3=24.
12×3=36-12=24.
So 24=24
Your answer is A.
