A(1) = - 3 ;
a(2) = a(1) + ( 2 - 1 )d ;
3 = -3 + d ;
d = 6 ;
a(3) = a(1) + ( 3 - 1)d;
9 = - 3 + 2d ;
12 = 2d ;
d = 6 ;
a(4) = a(1) + ( 4 - 1 )d ;
15 = -3 + 3d ;
18 = 3d ;
d = 6 ;
Then, a(n) = - 3 + ( n- 1 )6 ;
a(n) = - 3 + 6n - 6 ;
a(n) = 6n - 9 is an explicit functin rule for the sequence -3, 3, 9, 15, ...
Answer:
y =
x + 5
Step-by-step explanation:
The Line equation is:
y =
The line equation is in the form of y = m x + c
Slop of this line is (m1) = 
Let another line with slop (m2) , passes through point (4 , 2)
As per question the another line is parallel to the given line equation
So, slop of both the lines are equal
∴ (m2) = (m1) =
Hence equation of another line with slop
and passing through points ( 4 , 2) is
y - y1 = (m2) (y - x1)
I.e y - 2 =
(x - 4)
Or,
Or , 4y - 8 = -3x + 12
Or, 4y = -3x + 12 + 8
Or , 4y = -3x + 20
∴ y =
x + 5
Hence The value of y =
x + 5 Answer
Answer:
D
Step-by-step explanation:
A dicimal sign is the same thing as a division sign, so if I do 7 divided by 14 it would be 0.5 if I do 3 divided by 12 it would be 0.25 if I do 10 divided by 16 it would be 0.625 and if I do 5 divided by 15 it would be 0.333333333.
Hello,
+++++++++++++++++++++++++++++++++++++++++
Thanks for the incorrect formula!

I have tested (fog)(x) ,(f*g)(x) and finally (f+g)(x)
f(x)=6x++++++++++++++++++++++++3
g(x)=x-7
(f+g)(x)=6x+3+x-7=7x-4
(f+g)(3)=7*3-4=17

Answer:
20 degrees
Step-by-step explanation:
we can consider 33 to be the radius of a circle.
31 would then be the cos of the angle in that circle.
the regular cos function is defined for the standard circle with radius 1. so, that would be multiplied by 33 for this circle here.
31 = cos(?) × 33
cos(?) = 31/33 = 0.9393...
? = 20.05 ≈ 20 degrees
