The inequality of the given question is x+2y ≥ 150

Step-by-step explanation:

Given,

The mark out of 100 for Term 1 exam and twice the mark out of 100 for the term 3 exam are added together.

And, he needs to obtain 150 to achieve the grade.

To find, the inequality to student mark

Let,

The student got x in Term 1 and y in Term 2.

To be passed, he needs to get x+2y

So, the requited inequality will be x+2y ≥ 150

Marcus needs to bike at least 80 mi this week for a training if he has already bike 25 mi this week then how many miles should h
Rashid [163]

Marcus needs to bike at least 11 miles each day.

Step-by-step explanation:

Given,

Distance to cover = 80 miles at least

Distance already biked = 25 miles

Number of days left = 5

Let,

x be the distance to cover in 5 days.

According to given statement;

Number of days left * Distance to cover + distance already bike ≥ Total distance to travel

5x+25\geq 80\\5x+25-25\geq 80-25\\5x\geq 55

Dividing both sides by 5

\frac{5x}{5}\geq \frac{55}{5}\\x\geq 11

Marcus needs to bike at least 11 miles each day.

The slope formula can be used to find the slope, m, of a line with points (L1, y1) and (22, 42).
Helga [31]

Answer: (y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)

Step-by-step explanation:

Point slope form: (y-b)=n(x-a) , where n=slope , (a,b) is the point through which line passes.

If slope of the line = m and line passes through (x_1,y_1) and (x_2,y_2) :-

(y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)

So, the equivalent equations are :

(y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)
