Answer:
1. D. 1
2. B. y=a³/x
3. A. y=1/x
Step-by-step explanation:
too long to give te explanations but they're there in the attachments
The factors would be (x +7) and (x - 1)
Answer and explanation:
V originally equals u + at, but when you plug in u, a, and t you get a number answer.
u = 2
a = 15
t = 1/5
Rewrite the expression with the numbers plugged in.
V = (2) + (15)(1/5) <em>Multiply 15 by 1/5</em>
V = 2 + 3 <em>Add 2 and 3 together</em>
V = 5
<h2><u>So V would equal 5</u></h2>

Answer:
The roots are real and distinct.
Step-by-step explanation:
Given the following equation:

In this problem, a = 1, b = k and c = -k - 2
The discriminant is b² - 4ac, and for the roots to be real and distinct, it must be at least or greater than 0.
We get,
(k)²- 4(1)(-k - 2) = 1 - 4(-k - 2)
= k² + 4k + 8
Let's check:
At k = -2,

At k = 0,

At k = -100,

Therefore, we can conclude that for all values of k, the roots are real and distinct.
This has been a long way in answering this question, so it would be great if you could mark me as brainliest
