Im pretty sure is teh 3rd one
Answer:
25.1333 per second
Step-by-step explanation:
1508 per min
Answer: 4 hours
Step-by-step explanation:
Assume x is the number of hours taken.
Garage A would therefore charge a total of:
= $9 + $1.50 * x
= 9 + 1.50x
Garage B would charge:
= $5 + $2.50 * x
= 5 + 2.50x
To find the number of hours it would take for them to be the same, equate both equations:
9 + 1.50x = 5 + 2.50x
9 - 5 = 2.50x - 1.50x
4 = 1x
x = 4 hours
That cost would be:
= 9 + 1.50 * 4
= 9 + 6
= $15
Answer and step-by-step explanation:
5. To arrange it, find its value first:
4 - 6 = -2
-4 + 6 = 2
-4 - 6 = -10
So to arrange it from the least to greatest, it would be:
-10 , -2, 2 = c => a => b
8. To know which one have the least solution, calculate all of it first:
a. x + 5 = 13
Subtract both side by 5
x = 13 - 5
x = 8
b. -6x = -30
Divide both side by -6
-6x / -6 = -30/-6
x = 5
c. x / 4 = 18
x = 18 * 4
x = 72
d. x - 2 = -11
x = -11 + 2
x = -9
So d. have the least value (-9)
9. a. 10x - 4x = 6x
b. -15n + 3n = -12n
c. 7.5y + 1.6y = 9.1y
d. m + 4 - 2m = m - 2m + 4 = -m + 4
10. Student B are the students who invole in both piano and the band (As you can see it is in the middle of the diagram and it located in both circle (diagrams) so it would be both
Student G is the student who in the band because they only located in the band circle (diagram)
Hope those would help you :3

Answer:
Step-by-step explanation:
the zeros are -5, and -6
x+ 6 = 0 so x= -6 ; at this zero the graph crosses the x-axis because the degree for (x+6)^1 is 1 the multiplicity is 1
x+5 = 0 so x= -5; at this zero the graph crosses the x-axis because the degree for (x+5)^3 is 3 and the multiplicity is 3
Useful facts to know ;
If the multiplicity is odd the graph crosses the x-axis,
if the multiplicity is even the graph touches the x-axis and go
