Xf(x) = 2x + 5 1 7 2 9 3 11 4 13 5 15 6 17 linear functions grow by equal differences over equal intervals. in the table above, what column could be added to prove this relationship?

19

Step-by-step explanation:

Given is a funciton

The table shows x values as 1,2,3...6

f(x) values as 7,9,11...17

Since f(x) is linear there is a constant slope

Slope =2

This shows that for a unit change in x, there is a 2 increase in f(x)

By this property, we get when 6 increases to 7, 17 will change to 19

i.e. 2 will be added to 17 to get next table value.

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
