Answer:
Standard form for straight line y = m x + b where m is slope
m' = -m or m * m' = -1
answer a or y = - 8/7 + 4 satisfies this requirement
Answer:
steps below
Step-by-step explanation:
cos 23° = 6/x
0.92 = 6/x
x = 6/0.92 = 6.52
Answer:
B. 199
Step-by-step explanation:
We are given an Arithmetic sequence : 3, 7, 11, 15, ...
We are supposed to find the 50th term .
So, first consider the formula of nth term in Arithmetic mean:

where
a is first term of sequence
n is term position
d is common difference
= the term you are supposed to find
Now,
a = 3 ( first term )
n = 50 th term ( given )
d = 7-3 = 11-7 = 4(common difference
Substitute these value in the formula given above
⇒
⇒
⇒
⇒
Hence ,The 50th term of given arithmetic sequence is 199
So, OPTION B is correct .
Answer:
c= 12.19
Step-by-step explanation:
Let's solve for c.
5.3(4x−2.3)=21.2x+c
Step 1: Flip the equation.
c+21.2x=21.2x−12.19
Step 2: Add -21.2x to both sides.
c+21.2x+−21.2x=21.2x−12.19+−21.2x
c=−12.19
Answer:
c=−12.19
