Step-by-step explanation:
Let me just say that that's an amazing picture
ok
standard form is ax+by=c where a,b, and c are integers and a is usualy positive
18y=24x-9
minus 18y both sides
0=24x-18y-9
add 9 to both sides
9=24x-18y
24x-18y=9
divide both sides by 3
8x-6y=3 is standard form
Answer:
cos2∅= -0.557
tan2∅= --1.49
Step-by-step explanation:
Given:
cos∅=-8/17
By trigonometric ratios:
as cos∅=adjacent/hypotenuse
hypotenuse= 17
adjacent=-8
Now finding perpendicular using Pythagoras theorem:
c2=a2+b2
17^2=(-8)^2+b^2
289-64=b^2
b^2=225
b=±15
b=-15 as ∅ is in third quadrant so both the opposite and adjacent sides be in 3rd quadrant
tan∅=opposite/adjacent
tan∅=-15/-8
sin∅=-15/17
Now finding cos2∅
cos2∅= 1-2sin^2∅
=1 - 2(-15/17)^2
=1 -450/289
= -161/289
=-0.557
finding tan2∅
tan2∅= 2tan∅/1-tan^2∅
= 2(-15/-8) / 1-(-15/-8)^2
= (15/4) / 1-225/64
=(15/4) / (-161/64)
= -240/161
=-1.49 !
Answer:
Step-by-step explanation:
We just need to evaluate the function at -2.
The function is:
Therefore, g(-2) will be:
I hope it helps you!
Inupt values for y and evaluate to get y values
(x,y)
if x=0
y=3(0)-1
y=0-1
y=-1
(0,-1)
if x=1
y=3(1)-1
y=3-1
y=2
(1,2)
if x=2
y=3(2)-1
y=6-1
y=5
(2,5)
if x=3
y=3(3)-1
y=9-1
y=8
(3,8)
look for the points
(0,-1) (1,2) (2,5) (3,8)
