Answer: see below
<u>Step-by-step explanation:</u>
12) 2(x + 4) = 8
<u> ÷2 </u> <u> ÷2 </u>
x + 4 = 4
<u> -4 </u> <u> -4 </u>
14) 4w - 2(1 - w) = -38
4w -2 + 2w = -38
(4w + 2w) - 2 = -38
6w - 2 = -38
<u> +2 </u> <u> +2 </u>
6w = -36
<u> ÷6 </u> <u> ÷6 </u>
16) 10(1 - 2y) = -5(2y - 1)
10 - 20y = -10y + 5
<u> +20y </u> <u>+20y </u>
10 = 10y + 5
<u> -5 </u> <u> -5 </u>
5 = 10y
<u> ÷10</u> <u> ÷10 </u>
Assuming the values following t are subscripts since this is a sequence:
The +4 tells that the Common difference of each term following the previous one is 4. You could keep adding by doing
t2=t1 + 4 t2=2+4 = 6
t3=t3 + 4 t3=6+4 = 10
.....and so on.
Or you could turn the recursive rule
tn=t(n-1) + 4 into an explicit rule.
tn = t1 + 4(n-1)
So, tn = 2 + 4(n-1)
where n is the term number.
To the sixth term, make n=6 and solve.
t(6) = 2 + 4(6-1)
t(6) = 2 + 4(5)
t(6) = 2 + 20
t(6) = 22
So the sixth term in this sequence is 22.
The correct answer is 0.785
An undefined slope: x = a
(2; 5) ⇒ x = 2 and y = 5
therefore an answer: x = 2.
