The number of problems assigned as homework by a savvy math professor is a function of the length of the class on a particular day, which is either 454545 minutes, 909090 minutes, or 135135135 minutes. He first multiplies the number of minutes by 444 and then divides that number by 999. Finally, he subtracts 121212 from that amount. Which of the following functions best represents the number of math problems the professor assigns depending on the length of the class, ttt, in minutes?

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
