Question

# 2(p + 1) + 8(p - 1) = 5p

What value of *p *is the solution of the equation above?

## The correct answer is: the value of p is 6/5

2(p+1)+8(p-1) = 5p

- Lets solve the brackets first

2p + 2 + 8p – 8 = 5p ------------[ a(b + c) = ab + ac ]

- Adding the like terms

10p – 6 = 5p --------------[2p + 8p=10p , 2 – 8 = - 6]

- Subtract 5p from both sides

5p – 6 = 0

- Add 6 from both sides

5p = 6

- Divide both sides by 5

p = 6/5

- Therefore the value of p is 6/5

In the *xy*-plane, the graph of which of the following equations is perpendicular to the graph of the equation above?

The slope-intercept form is one of the most common ways to represent a line's equation. For example, the slope of a straight line, slope-intercept, and y-intercept formula determine the equation of a line (where the line intersects the y-axis at the point of the y-coordinate). An equation must be satisfied by each point on a line. For example, the graph of the linear equation y = mx + c is a line with slope m and y-intercept m and c. This is known as the slope-intercept form of the linear equation, and the values of m and c are real numbers.

¶A line's slope, m, represents its steepness. Sometimes the slope of a line is referred to as the gradient. A line's y-intercept, b, represents the y-coordinate of the point where the line's graph intersects the y-axis.

### Alan drives an average of 100 miles each week. His car can travel an average of 25 miles per gallon of gasoline. Alan would like to reduce his weekly expenditure on gasoline by $5. Assuming gasoline costs $4 per gallon, which equation can Alan use to determine how many fewer average miles, *m*, he should drive each week?

To calculate average miles, divide the total distance traveled by the time spent traveling. This will provides us with your average speed.

So, for example, if Ben traveled 150 miles in 3 hours, 120 miles in 2 hours, and 70 miles in an hour, his average speed was about 57 miles per hour. In this case, Alan can travel a hundred miles per week at 25 miles per gallon of gasoline to save $5 per week on gas, assuming gasoline costs $4 per gallon.
