Answer:
12.48
Step-by-step explanation:
Judging by the answers, the meaning of S4 is the sum of the first 4 terms of the series. That would be
10 + 2 + .4 + .08 = 12.48
F(x) = 7(x-1)+8
F(1) = 7(1-1)+8
F(1) = 7(0)+8
F(1) = 8
<span>The inequality is 4 ≥ x/2.1, and the answer is 8.4 ≥ x (or x ≤ 8.4).
Explanation:
"No less than" means it can be more than this or equal to, so we use 4 greater than or equal to.
Quotient means division, so we write x/2.1.
To solve this, we multiply both sides by 2.1:
4*2.1 ≥ x
8.4 ≥ x.</span>
4 I’m not that sure though
Answer:
y = 1.44
Step-by-step explanation:
What are you aiming to do here? Please share all instructions with each problem.
If you want to solve 4.5/y = 12.5/4 for y: Multiply both sides by 4y:
18 = 12.5y. Then y = 1.44
