Answer:
b.) All real numbers.
Step-by-step explanation:
4 (<em>a </em>+ 3) = 12 + 4<em>a </em>
4<em>a</em> + 12 = 12 + 4<em>a </em>
4<em>a </em>+ 12 - 12 = 12 + 4<em>a </em>- 12
4<em>a </em>= 4<em>a </em>
4<em>a</em>/4 = 4<em>a</em>/4
0 = 0
All possibilities of other <em>real </em>number can fit into the equation. Hence, the answer is b.) All real numbers.
1/4 exact form, 0.25 decimal form.
1.25.
The common ratio r is 1/5 and the first term a1 = (1/5)^(1-1) = 1.
Sum to infinity = a1 / (1 - r)
= 1 / (1 - 1/5)
= 1 / 4/5
= 5/4
= 1.25 (answer)
y = -3/2 x + 4
y-4 = -3/2 ( x-0)
