Answer:
The answer is a(7x+9)
Step-by-step explanation:
Answer: The tan 130° is expressed as 
Step-by-step explanation:
Since we have given that
As we know that
cos (π - θ ) = -cos θ
so, cos(180-50)=-cos 130° = -a
so, sin 130° would become
So, tan 130° is given by
Hence, the tan 130° is expressed as
So the problem statement wants us to convert a regular equation to a linear equation form, with slope and y-axis intercept, let's do try that:
2(y - x) = 2y - 14
2y - 2x = 2y - <span>14
-2x = -14
x = 7
Therefore we cannot have an equation of the form linear with slope and y intercept, but we do have </span><span>x = 7 which is a line equation as well, it means that for any value of y, x will always be 7, that is a line parallel to y-axis passing through x = 7 point</span>
Answer:
4.8%
Step-by-step explanation:
21% of 18
following the BODMAS rule, OF means multiplication
and also this sign% always means 100
so,it will be 21/100 * 18/1
this a laptop so i cant put it in a fraction way.....okay
this is how it shows...21/100 * 18/1
lets divide....
21/100 * 18/1
we will use 2 to divide
2 in 100=50
2 in 18=9
so it will be 21/50 * 9/1
nothing can divide so we will multiply
21*9/50*1
189/50=3.78≈4.8%
