Answer:
a) I used the equation x=-5; f(x)=-11 and x=-4; f(x)=-3. We get the range = -3-(-11)=8
b) I used the equation x=-5; f(x)=-11 and x=-3; f(x)=5. We get the range = 5-(-11)=16
c) I used the equation x=-5; f(x)=-11 and x=-2; f(x)=13. We get the range = 13-(-11)=24
d) Range of input is equal with the ratios of the output. You can find the pattern of output above 8,16,and 24 can divided by 8 and give the result 1,2 and 3
I think the slope (m) should be 16.
The number of cans needed to paint an area covering 2,200 sq. units will be given by:
number of cans=[area required to be painted]/[area that 1 can of paint can cover]
=2200/400
=5.5
Therefore we conclude that we will need 5.5 cans of paint
3 cups for each student implies 3*48=144 cups for 48 students.
1 quarts is equivalent to 4 cups, 144 cups will give 144/4 = 36 quarts.
Change of y / over change of x
Go over 4, up 45
B is your correct answer
Hope this helps!
