Answer:
The answer to your question is: The second option
Step-by-step explanation:
Points A (3 , 7) B (5, 11)
slope = m = (y2 - y1) / (x2 - x1)
m = (11 - 7) / (5 - 3)
m = 4 / 2 = 2
equation if the line
(y - y1) = m(x - x1)
(y - 7) = 2(x - 3) Answer
To solve this question, we just need to insert 12 into the m position of each question and see if the equation holds true.
a. 4m = 40
4(12) = 40
48 = 40
48 obviously does not equal 40, so it is not choice A.
b. m + 20 = 42
12 + 20 = 42
32 = 42
Again, 32 isn't the same as 42, so not choice B either.
c. 4m = 48
4(12) = 48
48 = 48
It looks like this one is true, but let's solve D also just to make sure.
d. m - 4 = 9
12 - 4 = 9
8 = 9
This is false, since 8 does not equal 9.
Therefore, choice C (4m = 48) is the correct answer.
Hope that helped! =)
Using sine formula we have
8/sin60 = x/sin30
hence x= 8/√3 = 4.62
Doesn’t let me in the link?
3. i=129; j=112
4.k=90;l=116;m=64;n=86
5.o=13;p=78;q=91
6.a=120;b=60;c=140
Can't see #7
You did 8 I believe
9.v=39;w=59;x=121
10.y=59;z=93
11.a=42;b=48;c=132
12.a=60;b=50;c=80;d=100
