Given 4x − 8y = 8:
siniylev [52]
4x - 8y = 8
8y = 4x - 8
y = 1/2 x - 1

slope: 1/2
y-intercept:(0, -1)

Line perpendicular- negative reciprocal slope

y-(-1) = -2 (x-0) Hahaha I don't know what is the point slope form though hahaha not sure with this.

What is the measure angle of F?<br> I already know it's 140, but how do you arrive at that answer?
serg [7]
So the angles combined should be 360 and we already know h is 90 degrees. so the rest should equal 270. Just set up an equation of:

9x + 14x + 4x = 270

then solve for x, first combine like terms

27x = 270

then get x alone by dividing

x = 10

then plug 10 into the problem next to angle f: 14x

14 * 10 = 140

Use math notation to describe the following sequence: <br> 1, -1, 1, -1,...
Veseljchak [2.6K]

Answer:

The math notation to the given sequence is  a_n=(-1)^{n+1} for n=1,2,3,... is verified and it is true

Step-by-step explanation:

Given sequence is 1,-1,1,-1,...

Let a_1=-1,a_2=1,a_3=-1,a_4=-1,...

To find the math notation for the given sequence :

a_n=(-1)^{n+1} for n=1,2,3,... verify that it is true or not

Put n=1 in the above equation we get

a_1=(-1)^{1+1}

=(-1)^2

Therefore a_1=1

Put n=2 in the a_n=(-1)^{n+1} equation we get

a_2=(-1)^{2+1}

=(-1)^3

Therefore a_2=-1

Put n=3 in the a_n=(-1)^{n+1} equation we get

a_3=(-1)^{3+1}

=(-1)^4

Therefore a_3=1

and so on

Therefore the math notation to the given sequence is  a_n=(-1)^{n+1} for n=1,2,3,... is verified and it is true
