The slope-intercept form of the linear function is y = m x + b , where m is the slope and b is y-intercept.
Here we have: y = 3 x - 3
a ) When y = 0
0 = 3 x - 3
- 3 x = - 3
x = ( - 3 ) : ( - 3 )
x = 1
When x = 0
y = 3 * 0 - 3
y = - 3
So x - intercept is ( 1, 0 ) and y-intercept is ( 0, - 3 ).
b ) The slope:
m = ( y2 - y1) / ( x2 - x1 ) =
= ( - 3 - 3 ) / ( 5- 7 ) = ( - 6 ) /( - 2 ) = 6 / 2 = 3
Answer: The slope m = 3 .
I would try to find the Constant of proportionality of the sequence maybe or try to find what the sequence starts with and then multiply it by 87 . Hope this helps
For 95% CI
x - 0.05s = 100
x + 0.05s = 120
Solve for x and s
The interval for u with 90% is
x - 0.10s
and
x + 0.10s
Substitute x and s
Answer:
tanx = 2
Step-by-step explanation:
Given (1 + tanx) / (1 + cotx) = 2
Using the formula:- cotx = 1 / tanx.
Change cotx into tanx in the equation:-
(1 + tanx) / (1 + 1/tanx) = 2
(1 + tanx) / {(tanx + 1) / tanx} = 2
Keep Numerator as it is, Change division to multiplication, Flip denominator:-
{ (1 + tanx)/1 } * { tanx/(tanx + 1) } = 2
tanx * (1 + tanx) / (tanx + 1) = 2
tanx = 2
Hence, the answer is tanx = 2.
