The graph models the linear relationship between the cost of car repairs and the number of hours needed to complete the repairs.
Which of these best describes the rate of change of the cost with respect to time and the
y-intercept of the graph?
A Rate of change = 40, y-intercept = 25
B Rate of change = 4, y-intercept = 0
C Rate of change = 25, y-intercept = 40
D Rate of change = 0,y-intercept=4

30

step-by-step explanation:

idk

i hope i

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
