Answer:
You have to graph and label the points
Step-by-step explanation:
3x-5 is just a straight line which is lesser than or equal to -1 so that is a closed circle
-2x+3 is another straight line which is (both open circle) which its domain is restricted from -1 to 4
2 is just a horizontal line starting at (closed circle) 4, it is greater than also.
If you don't understand the the constants (the numbers on their own) just a vertical translation.
If the cross either the x or y axis, you have to find that too, im pretty sure.
To find the y axis intercept, make x = 0 and solve for y
and to find the x axis intercept, make y = 0 and solve for x
Have you learned PEMDAS? (Parenthesis, exponents, multiplication, division, addition, subtraction). That is what I am going to do here.
The first parenthesis, let's solve. 7*10=70-5=65
The second parentheisis: I am assuming the negative sign is a typo, and this answer will be off if it is not. Sorry. 5*10=50
65*50=3250
I hope this helps, and let me know if you need further assistance.
Answer:A
Step-by-step explanation:
0=-2x^2+x+3
-2x^2+x+3=0
a=-2 b=1 c=3
Answer: 225m^3
Step-by-step explanation:
Volume = Bh where "B" is the area of the base and "h" is the height
So, area of the base = 1/2(length)(height) = 1/2(5)(9) = 22.5 m^2.
Then multiply by the height.
22.5x10= 225m^3
The <em><u>correct answer</u></em> is:
639.4 minutes.
Explanation:
Saturn takes 10 hours, 39 minutes and 24 seconds to make a complete rotation.
10 hours × 60 minutes per hour = 600 minutes.
600 minutes + 39 minutes = 639 minutes.
24 seconds out of 60 seconds per minute = 24/60 = 0.4.
This gives us 639+0.4 = 639.4 minutes.
