Answer:
-4<x<-1
Step-by-step explanation:
To solve the problem, we divide the whole expression by 2:
2x^2 + 10x < –8 → x^2 + 5x < –4
→ x^2 + 5x + 4 < 0
Factorizing
→ (x+4)(x+1) < 0
The expression is ONLY negative when:
x>-4 and x<-1
Therefore, the solution is:
-4<x<-1
Answers:
Center = (4, 7)
Radius = 7
===========================================================
Explanation:
The general template of any circle is
(x-h)^2 + (y-k)^2 = r^2
This general circle has these properties:
Based on the equation your teacher gave you, we see that
- h = 4
- k = 7
- r = 7, since 7^2 = 7*7 = 49
Therefore, this circle has center = (4,7) and radius = 7
Side note: The center's y coordinate and radius aren't always the same value.
Answer: x = -4; x = -1; x = 3
see in this graph, at x = {-4; -1; 3} => y = 0
=> the zeros of the function are -4; -1; 3
Step-by-step explanation:
Answer:
The formula: e7 = (b7*d7)+(c7*d7*1.5)
Step-by-step explanation:
Given:
Hours worked = b7
Hourly rate = d7
Overtime hours = c7
Salary calculation = e7
Salary = Hours worked*hourly rate + (overtime*hourly rate)*1.5
Formula
e7 = (b7*d7)+(c7*d7*1.5)
The formula e7 = (b7*d7)+(c7*d7*1.5)
Hope this will helpful to you.
Thank you.
