Answer:
x^2=5-x
x^2+x-5=0
x=-1± √(1)^2-4(1)(-5) /2(1)
-1± √21 /2

Answer:
Volume is increased in a factor of 8. The volume is increased from to .
Step-by-step explanation:
The formula for the volume of the rectangular prism is:
Where:
- Width
- Height
- Length
If dimensions are doubled, then volume is increased in a factor of 8:
The volume is increased from to .
Answer:
C: y ≤ 2x − 2 y > −x + 3
Step-by-step explanation:
The shading for region A is above a dashed line with negative slope, so will be the solution of an inequality that matches y > -ax +b. Choices A and C have such an inequality.
The shading for region B is below a solid line with positive slope, so will be the solution of an inequality that matches y ≤ ax +b (for some positive a). Choice C is the only one wht the appropriate inequality symbol.
Comparing choice C in detail with the graph, we find that it matches. The line with negative slope has a slope of -1 and a y-intercept of 3, so region A matches y > -x+3. The line with positive slope has a slope of +2 and a y-intercept of -2, so region B matches y ≤ 2x -2.

Answer:
It's the second one
Step-by-step explanation:
It's the second one because 75 dollars is only being charged once and 25 dollars is being charged x amount of hours so you would make the equation
y = 25x + 75
Can I have brainliest? It would help me out, if not thanks anyways! Hope this helped and have a nice day!
