Answer:
19. (-∞,-5)U(-5,2)U(2,∞)
20. (-∞,-6)U(-6,4)U(4,∞)
21. (-∞,10)U(-10,3)U(3,7)U(7,∞)
Step-by-step explanation:
To summarize these three equations, ignore the numerators for every three equations listed, flip the + and - for each side to get the x values. You have to put the values from smallest to largest in order to state the domain. You need this sign -> U for the answers.
Answer:
34 units
Step-by-step explanation:
The perimeter of a triangle is given by the sum of the lengths of its three sides.
So if the perimeter is 68 units and the sides measure x, 2x and 3x, we have that:
x + 2x + 3x = 68
6x = 68
x = 68/6 units
Now with the value of x we can find the length of EO:
EO = 3x
EO = 3 * (68/6)
EO = 68/2 = 34 units
Answer:
The midpoint of CD is (3, 2)
Step-by-step explanation:
The movement of x is +2 from C to D and the movement of y is 16 from C to D
2 (C's x coordinate) +2/2 (to find the movement up to the x coordinate of the midpoint) and -6 (C's y coordinate) + 16/8 (to find the movement up to the y coordinate of the midpoint)
This is 2+1 as the x coordinate and -6+8 as the y coordinate that is (3, 2)
288 divided by 12 = 24
240 divided by 10 = 24
Your formula would be 3(p+0.75)=5.88
Because you have 3 pounds and 0.75 for each.
Solving the equation by distributing, you will get P=1.21
Hope this helps!
