Question 4(Multiple Choice Worth 4 points) (04.01 MC) Carla and Jonah are working together to determine if quadrilateral CDEF with coordinates C(2, 3), D(1, 2), E(4,1), and F(5,3) Carla sets up the following equations: 2-3 mco 1-2 1-2 4-1 IMBE Jonah sets up the following equations: 2-3 mco 1-2 3-1 mer 5- 4 Who is on track to get the correct answer and why? Carla is on the right track because she is finding the slopes of the opposite sides to check for right angles. O Carla is on the right track because she is finding the slopes of consecutive sides to check for right angles. Jonah is on the right track because he is finding the slopes of the opposite sides to check for right angles. O Jonah is on the right track because he is finding the slopes of consecutive sides to check for right angles. please answer asap :/​

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 : )

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
