Explain the error that was made and how you solve sit correctly . Identify the correct answer in the equation below . Which was the incorrect step ?

Step 1: 8x-7>17+12x
Step 2: -4x-7>17
Step 3: -4x>24
Step 4: x>-6

Explain the error :
Correct Answer :

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

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

thus, the first answer choice, y = sec x, is the correct one

is there more to this question?
