Answer:
y = 4x + 48
Step-by-step explanation:
Slope intercept form: y = mx + b
y - 8 = 4x + 40
y = 4x + 48
Direct variation:-
y = kx where k is a constant
y=12 when x=6 so we have:-
12 = k*6
k = 12/6 = 2
so our equation of variation is y = 2x Answer
Answer:
15
Step-by-step explanation:
By the diagram, you can see the sum of segment AB and segment BC is segment AC. Adding the given expressions for AB and B is
. Simplifying the equation
, gives
. Substituting
in the equation for segment AC gives 15.
