This line y = 4/5 x - 3 has slope = 4/5

Perpendicular lines, slope is opposite and reciprocal so slope of a line that is perpendicular to the line y = 4/5 x - 3 is -5/4

Answer

- 5/4

The slope of a line perpendicular to a line with slope x is - $\frac{1}{x}$ . it is the opposite reciprocal. The slope of this line is 4/5. The first step in finding the slope of a line perpendicular to this line is to take the reciprocal of it, which gives us 5/4. The final step is to multiply it by negative 1. This gives us our answer of -5/4.

Answer: About 29

Step-by-step explanation: First you need to add all the numbers together. Then you divide the sum, 235, by however many numbers you have (8). And BOOM: you got your answer :)

PS: If you have a decimal number, just round it up or down ( 5 and above give it a shove; 4 and below let it lie low)!

a 56-inch board is to be cut into three pieces so that the second piece is three times as long as the first piece and the third

jeyben [28]

Step-by-step explanation:

length of 1st piece = x inch

length of 2nd piece = 3x inch

length of 3rd piece = 4x inch

x + 3x + 4x = 56

8x = 56

x = 7

Thus,

length of 1st piece = 7 inch

length of 2nd piece = 3 × 7 = 21 inch

length of 3rd piece = 4 × 7 = 28 inch

Find the equation and write in slope-intercept form

defon

So, let's first find the slope of the second question:

$2y=x+3 \implies\\ y=\frac{x}{2}+\frac{3}{2}$

Our second equation has a slope of one half, so we know that a line perpendicular to it will have the negative reciprocal slope of that, so -2. We have this now as our equation:

$y=-2x+b$

We are given the point (3,-6), so let's plug the x and y in and find our b:

$-6=-2(3)+b \implies\\ -6=-6+b \implies\\ 0=b$

Since our b is 0, our equation is simply:

$y=-2x$
