Answer:
4, 16
Step-by-step explanation:
[tex] a_n = 3a_{n - 2} - a_{n - 1} - 1 [/tex]
Let's see if it works for a_3:
[tex] a_3 = 3a_{1} - a_{2} - 1 [/tex]
[tex] a_3 = 3(3) - (4) - 1 [/tex]
[tex] a_3 = 4 [/tex]
Yes, it works for a_3.
Now let's calculate a_4.
[tex] a_4 = 3a_{2} - a_{3} - 1 [/tex]
[tex] a_4 = 3(4) - (4) - 1 [/tex]
[tex] a_4 = 7 [/tex]
a_4 is also correct.
Let's calculate a_5.
[tex] a_5 = 3a_{3} - a_{4} - 1 [/tex]
[tex] a_5 = 3(4) - 7 - 1 [/tex]
[tex] a_5 = 4 [/tex]
Let's calculate a_6.
[tex] a_6 = 3a_{4} - a_{5} - 1 [/tex]
[tex] a_6 = 3(7) - 4 - 1 [/tex]
[tex] a_6 = 16 [/tex]

angles sum: 180(6-2) = 720
50 + 37 + 42 = 129
129 + 5x + 7x - 1 + 3x + 40 = 720
15x + 168 = 720
15x = 552
x = 36.8
check:
129 + 5(36.8) + (3(36.8) + 40) + (7(36.8) - 1) = 720
Correct answer??
180-50 = 130
180-37 = 143
180-42 = 138
Known internal angles:
130 + 143 + 138 = 411
15x + 39 + 411 = 720
15x = 270
x = 18

no, because the pythagorean theorem doesnt work out with those numbers.
Step-by-step explanation:
since (3^2)+(6^2) isnt 8^2
how many solutions does 6-3x=4-x-3-2x
Answer:
0
Step-by-step explanation:
6 - 3x = 4 - x - 3 - 2x
6 - 3x = -3x + 1
Add 3x to both sides.
6 = 1
Since the last equation, 6 = 1, is false after doing legal steps, that means that the equation is false and has no solution.
Answer: 0
Find the equation for the line that passes through (4, - 8) that has slope - 2. Give your answer in
point-slope form. You do not need to simplify.
Answer:
y+8=-2(x-4)
Step-by-step explanation:
point-slope form is y-y1=m(x-x1) where m is the slope, and (x1,y1) is a point.
We are given all of that information:
slope: -2
point: (4,-8)
substitute the numbers into the equation
y--8=-2(x-4)
we can make --8 to positive 8
so:
y+8=-2(x-4)
this is the equation in point-slope form
Hope this helps!

[tex]6y - 8 + 2[/tex]
simplify by combining like term
so it will end up at 6y-6
you need to combine everything that does not have an exponent (example. a, x, y) and you combine the ones that have exponents together. and therefore you get 6y-6 (remember positive and negative signs)

Answer:
∠BDC=43°
Step-by-step explanation:
Since ABCD is a rectangle, ∠ADC=90
∠ADC=∠BDC+∠ADB
90=(7x+1)+(9x-7)
90=16x-6
16x=96
x=6
∠BDC=7x+1
=7(6)+1
=42+1=43
