Answer:
-6 7/hr= -6F per hour
Step-by-step explanation:
a rate of change can be defined as:
R=(total change in some quantity) (time in which the change happened)
In this case we know that the temperature dropped -30F in a given time, then we already know that:
Total change in some quanity =-30F now we know that this change took place between the 1:00pm and the 7:00 pm the total amount of ime between these two hours is:
T= (7.00 - 1.00 hr)= 6.00 hr
this means that the change happened =6 hours.
then we can replace these values in the above equation to get:
R=(-30F)/(6hr)=-6F/hr
this means that for each hours that passes the temperature decreases 6F
we also can write that this rate as:
R=-6F/HR =-6F per hour.
12/25 players play soccer, and 300 students so 25 goes into 100 4 times multiply that by 3 to make 300 so you get 12 and then 12x12 its 144
1/6y - 4 = -7
1/6y = -7 + 4
1/6y = -3
1 = -18y
-18y = 1
answer
y = -1/18
Answer:
4x +10 + 3x +2 = 180 (since they're supplementary, the angles together =180)
7x +12 =180 (combine like terms on left side, and subtract 12 from both sides)
7x = 168 (divide both sides by 7 to isolate x)
x= 24
angle 1 = 4(24)+10 (plug x into the expression for each angle, and solve)
..................96 +10
angle 1 = 106 degrees (the measure of the first angle)
angle 2 = 3(24) +2
..................72 +2
angle 2 = 74 (the measure of the second angle)
106 +74 =180 (the two add up to 180, so they're supplementary)

I hope this helps :)
Answer:
y = 2
Step-by-step explanation:
y=2 every time you add 3 to x your adding 2 to the y
-3 + 3 = 0 and 3 + 2 = 5
0 + 3 = 3 and 5 + 2 = 7
