Solve for the equation for x.
3(10 – 4x) + 6 = 12

Step-by-step explanation:

3(10 – 4x) + 6 = 12

first you need to use the distributive property

30 – 12x + 6 = 12

then subtract 6 from each side

30 – 12x = 6

then subtract 30 from each side

– 12x = -24

divide both sides by negative 12

x = 2

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
